If you want help protect your vehicles don't forget about your keys. an emp can distroy the little chip inside, make sure you have a spare and protect it.
I worked in the paging industry in the nineties and we worked in screen rooms to tune the receivers. We needed to have the enclosure grounded to work properly. The other thing we had to contend with is the door and its frame ( same as the lid on the garbage can) the doors are equipped with special flexible metallic gaskets that enables an excellent electrical seal blocking out radio waves. I tested the cage with an HF radio transmitting outside the cage into a small antenna with a receiver on the same frequencies within the cage. We tested from 3 KHz up to 440 MHz and then with commercial equipment from 150 to 1 GHz with no intrusion of any of the signals. We were about five miles from a VHF low television station (ch4)and about a mile from a local high rise building with multiple high power paging transmitters and could not receive their signal inside the cage. Don't bother these cages started from 3K$ and the sky the limit depending on size, screened panels, isolation panels for electrical inputs, lighting options.
Thank you very much for your, informative industry backed information. Nothing against this guy's channel.But even from an educational point of view. His info didn't add up. Further, not all EMPs are created equal. As I understand it, a large high altitude nuclear detonation , would cause a over load. Like a very large lightning strike. Millions of volts of electricity. not frequencies. Thank you again.
I have a hard time believing that modern cars will not fail from a short waved EMP burst. They have so many interdependent components if one fails the whole car stops working.
Solar flares will eventually lead us back to using the very basic combustion engine technology..... Like a 2 stroke motorcross bike as the "new transportation" to get around 👍
I did a lot of work on the Mill EMP protected PCs, they were well sealed, and nothing, not even 1 seam was left open, 2 layers of stainless steal in most places, special metal gaskets, lots and lots of screws to insure proper mating of parts. If the relatively week cell signal can get into your can, what do you think the massive amount of energy from an EMP/CME will do? Best bet use the metal duct on every rivet, seam, and opening on the can, use nesting 2-3 layers deep. The foil tape is like $22 for 50 yards, Cheap when I look at 3 radios, 3 high dollar flashlights, 3 GPS units, 3 Red Dots and other electronics. Easy to open a razor knife on a string tied to the lid. Do you need this? Only you can decide but, if your going to do it, do it right.
While I believe the RF spectrum of frequencies can vary....in a properly placed nuclear explosion you could have EMP approaching or exceeding 50,000 volts in the pulse.. It will pass through metal with as little as 2% attenuation. Finding electronic devices inside and frying them. Cell phone demos are miniscule amount of RF energy. The ECM in cars/trucks will also take this 50KV pulse and many...many will be damaged. The ECM regulates fuel flow, spark, timing and many other functions to keep your vehicle running. If your vehicle is out of the pulse damage maximum then your damage may not be critical. My suggestion save your money building ineffective Faraday cages put it towards a bicycle or a horse. Get a Coleman Lantern because there is a good chance all LED flashlights could be toast also. Put money into food/water/supplies to tide you over for.a year or more. Own a gun you may need it for protection as well as food. I have lived long enough to remember living from well water and using an outhouse. We can get by without cell phones and the push button world we live in. Plan a plan and work your plan.
You forgetting something, like he said it's for dampening the effects, so if you are not that close to ground zero , but some reduction may save your devices.
Yes, and while on a " somewhat " related topic, the entire " 5g " used as a directed energy Weapon System, There will be nothing outside of a very deep Underground facility, as far away from the emitting devices as possible, to save a person from its effect. While i understand it is a " debated " topic, the entire concept of a Directed Energy weapon, more devastating and pervasive than an EMP, is a real possibility. And out of all massive, Humanity devastating weapons, with no loss of infrastructure.... Yeah, microwave attacks in the Ghz range is the MOST ideal.
It’s 2021, I have a faraday bag that does not allow a cell signal to ring my phone. Bluetooth doesn’t work in either direction even with only a fraction of an inch between two paired devices, one inside and one outside. The same is true of wifi/hotspots. I’m guessing physics has not changed in five years but I’m pretty sure there is something amiss with your cage. Still I appreciate the time and effort to produce this video! Stay safe and healthy!
Put some steel wool around the top of your cans instead of tape that the lid folds the wool over and forms a shield around the top. Now you can open it without destroying the shield like with tape. Also for more protection that is really needed is get a couple sizes bigger can and put the small can inside it.
I get people wanna save their stuff.. But why save your phone? Who the hell are you gonna call? There probably won't be any working towers for phone.. Let alone internet Get lanterns.... Get food.. Water..etc
I'm in the process of making two emp cans, and your covering the handle brackets prompted me to check on their connection to the lid. I turned the lid upside down and filled it with water. Yep, it leaked! So the top does indeed need more attention!
I placed a rubber trashcan with lid into my galvanized steel can, with wadded paper and Great Stuff foam to keep the rubber trashcan floating within the large steel can. I duct (cloth type, non-metallic) taped all openings on the lid of the rubber trashcan, but did NOT duct tape the edges of the rubber lid when placing it down tightly. I then set my phone inside, ready for normal calling etc. Then I put the rubber lid on tight, laid a towel on top as a spacer to help the metal can lid hold the rubber can lid down tightly, and put the metal lid on tightly. Then i used metal foil 2 inch HVAC duct tape (about $10 a longggg roll at HD or Lowe's) to wrap around the lid of the metal can, to completely close it. I also taped securely over the little holes where the can handles and the lid handle are, to close them on up. My first cell phone test was WITHOUT this metal taping.........and it was a wash........I could hear my phone inside ringing when I called it with my wife's phone. FAIL !!! So I find the metal foil tape, put my phone in, close her up and tape her up as described above. PERFECTO! NO ringing at all. Now the proof in the pudding: After slitting the tape, opening up the Faraday Cage, and retrieving my phone.......I take it and check for recent phone calls and texts, and there are none.........but about 2 1/2 minutes later the phone starts beeping with phone call and text updates coming in. Similar to how you have your phone turned off, turn it on, and soon the signals catch up with you........ only my phone was on the entire time, the signals just could not get to it within the Faraday cage. So next I will be testing it with walkie talkies to check other wave frquencies. The somewhat tedious part is having to retape it every time you open it up..........and the limited space, if you want to do more than just phones, cameras, walkie talkies and a old laptop or two. So I'm anxious to find an old heavy duty storage locker like this guy did in his other video, which he has set up to be able to just open the doors and retrieve tools and electronics, then close the door and be good to go......... With that crazy Rocket Man over there, we should ALL be taking greater measures to protect ourselves. Throw your old laptops into your cages, too.........they just might become the backbone of a new world after all our good gear gets fried in an EMP/Solar event.
You can stop the signals to the phone if you place a metallic cloth covered foam gasket around the inside of the lid of the can. The problem is that higher frequencies can get through very small gaps between the sides of the can and the lid. You want to do your best to reduce the signal levels by 50 decibels or more across the range of frequencies. Without proper sealing between the can and lid you’re only getting about 15 decibel reduction in the upper frequencies.
I've been gathering emergency kits, not just based on emps or nuclear war etc, when things like the pandemic hit, it's good to be prepared. you just never know what could happen. being complacent in life isn't good and so many of us have gotten that way because we don't want to believe or even think about things going seriously bad. ignorance isn't always bliss. I have just started learning how to make one, started out with just a ziplock bag, one I saved from light strips packaging and it's silver. heard it protects electronics to a certain degree when it's being shipped I guess... but I used copper tape and made sure it was completely covered , it's sealed with it all around and a little bit on the inside of lip of the bag. i did use my phone to test it, both withy regular cell service, Bluetooth and wifi. I had my Bluetooth speaker playing music from my cell and right when I zipped up the bag, it quit. made sure my ringer was cranked up and had my friend call me. from her end I heard it ring a couple times then it went straight to voicemail, my phone didn't ring itself. taking it out for the bag I noticed wifi was gone and LTE was used, but shortly after seeing that the wifi did come back. them I got my notifications of a missed call lol. so my device is still reachable kinda... I have to gain a better understanding about cellular service etc but mostly I did this to see what my google nest mini does along with the smart devices I have integrated to do certain things when I leave the house as I do have presence sensing turned on. be good to add a crank radio that has solar, uses a lithium battery or regular batteries to the cage thing I think. just in case. maybe SD cards loaded with your precious podcasts and other videos, music... a kindle lol. idk. it's all ingesting though and it should be the last thing to do when you are doing prep prep like this but good idea to take the time to learn about it while early prepping for when SHTF
What would have been nice, to us who know nothing much about EMP, is what would be affected without a Faraday Cage, ie: batteries in storage, turned off electronics, etc, and this would only take a minute or two to give a short summary. That would have given us a perspective about the effects of EMP so we can better understand the value of the Faraday Cage.
Stainless steel is a very poor conductor and a proper Faraday cage needs to be made from a highly conductive material. A copper can/mesh will block the cell signal. Your steel can is not able to effectively distribute the electric charge. Essentially, that’s not a Faraday cage, it’s a storage bin.
Consider that the amplitude from an EMP or solar flare is going to be a LOT stronger than radio or cell phone signals. If you're still getting through with those, you might want to quadruple or quintuple your protection.
Install a conducting gasket in your can and stop the rim acting as an antenna. The Dr. whose book you referenced proved that without the conductive gasket and he recommends several different types for ammo cans or garbage cans you lose a significant amount of DB reduction. I have the exact same can you have I used copper tape at the handle to secure that gap and tested it with cell phone and ham radio both with and without the gasket, but the gasket would stop cell phone and ham walkie-talkie communications completely. Your mileage may vary.
His book is WRONG. It is mis information to convince the GULLIBLES they are safe. Start with GROUNDING EVERYTHING to Earth. Home plumbing is NOT safe. 6 feet of copper rod is safe.😊
Have a neighbor who thinks his garbage can makes his Ham Radio SAFE. I laugh and walk away. If we get attacked by EMP, it will be so intense, even ungrounded Faraday cages will FAIL to protect contents. In the Military we shield using ALL grounded, with TRIPLE redundancy. Good luck, disregard this utuber who knows only fairy tales !
An effective Faraday cage is a good thing to have. The problem though is that there are too many misconceptions and flawed information about them. Even this video about misconceptions is a misconception gold mine. Some effective Faraday cage critical keys. 1) Must be electrically sealed. Even very small gaps will leak RF energy. The larger the gap. The longer the wavelength (lower the frequency) that gets leaked. 2) Use the most electrically conductive material practical. Not all metals have the same level of electrical conductivity. 1. Silver (best but cost prohibitive) 2. Copper (very good, expensive but affordable and available) 3. Gold (pretty good but very cost prohibitive) 4. Aluminum (probably the most practical) 5. Steel, iron and tin are further down the list. Line such containers with several layers of aluminum foil. Aluminum foil lined containers make pretty good Faraday cages if they are electrically sealed effectively (several continuous layers; any overlaying of seams must be by a significant amount). If electronic devices inside a Faraday cage receives a signal. Then it is not an effective Faraday cage and will not protect electronic devices from an EMP. A shoe box that is well lined with aluminum foil and electrically sealed well can be a good Faraday cage.
If the can is welded at seams then anything more can add nothing. Furthermore, the aluminum tape has an adhesive backing which may actually insulate, rather than add any conductivity.
Several of the studies are showing that even if a vehicle quits working after an EMP weapon, for a lot of the newer vehicles, they believe all that would be needed is to disconnect the battery then reconnect it to reset the vehicles sensors and most cars will run. I have been trying to tell people about this for years, but everyone believes that all vehicles will quit working and we will be in the stone-age after an EMP. I use several Faraday cages similar to yours, yet I have mine layered for additional protection at different frequencies. First I use a sealed aluminum foil covered box to store my important electronics in. Then I use a copper mesh material to wrap the aluminum foil box and seal it with copper tape. Then that is heat sealed inside an EMP bag, then the bag is placed in a galvanized can similar to the one you have there and is sealed with aluminum tape. I shouldn't have any problems after an EMP. Personally, I believe that we will be hit with a Super-EMP weapon within the next year which will be blamed on either Iran or North Korea, but I don't think either of them will really have their finger on the trigger. I think that finger will be a lot closer to home than most people want to admit or believe.
WH6FQE - The Kilted Piper how can I call you if your cellphone doesn't ring. Damn dude your mother called last night and was wondering why you don't answer the phone. I'll pass it on to her. :(
My Faraday cage doesn’t let phones ring when called. And cars made before ‘84 have a much better chance of running after an emp, the majority of pre 84 vehicles will still need to have things replaced like alternator and cylinoid and possibly battery, but with only 1 in 10,000 vehicles made after 84 even have a slight chance of operating!
I just put a 4g phone in a biscuit tin and it never even went to answer phone. Also, when I removed the lid there was no signal at all. You sure that's made of metal? If it is you need more ayers! Because I just used a simple biscuit tin and it worked. I read cordless house phones are more powerful so tried that in the same tin and it rang. You need more layers I just watched another experiment where 3 metal containers like the one you use were put over a router 1 after the other whilst the signal was checked each time. It took all 3 till the signal was lowered considerably. But every time one was placed over it the signal dropped.
was it a flip/dumb phone? It was easy to make a Faraday bag for my brand-new dumb phone (won't ring), but using the same material, a smart phone did ring. The antennae for the dumb phones are far, far weaker.
Purchase a backup computer module for your car model, wrap in in a few layers of foil and keep it under the seat just in case. Also, surges "confuse" memory circuits. Disconnect the negative terminal fro the battery for 15 min, then reconnect. It might start up.
If the emp takes out small electronics, won't it take out electric grid, cell towers, etc? Seems foolish to worry about having a phone if towers are down, grid down (transformers made in China) so no power except solar. Regular generators need fuel....that will eventually run out.
Cell phones will certainly not be able to make calls. But, if the EMP does not destroy yours, you may be able to use anything you saved to it. Offline maps, videos, etc.
The effects of EMP can be increased in nuclear weapons, and those ideas are classified. The higher the yield, the lower the EMP, but there are ways to enhance the EMP effect regardless of yield. Studies were conducted in 1962 during Operation Fishbowl in the pacific, but they didn't understand the full effects then. Much of it remains classified.
The anti static bag numbers are probably erroneous. The anti static bag's metal layer is so thin that the metal would likely melt and the plastic bag decay, under the current load and heating induced by a nuclear EMP. All tests we can run to check for shielding are at powers that are 5 to 6 orders of magnitude or more lower than power levels generated by a nuclear EMP.
Pretty sure the aluminum tape has non-conductive adhesive, so for this purpose you'd be better off with copper tape, which is used in electric guitar pickups.
nuclear missles do not fry all comms neither do coronal mass ejections but durring that time who will translate through common and temporal dilects durring the time of comms restoration
dude i got pissed when i could hear my phone in there. u got the same problem as me, conductive tape the gap where the lid touches the can and ur phone wont work anymore in there.
the guy that wrote the book you quote from has a video about sealing the can with the conductive tape. I believe he said with that, there was an 80db drop in his testing.
I have an metal brief case I was thinking of storing my laptop in when i was not using it in case there was an EMP. I tried to call my phone and it of course failed to block it as yours did. But would it stop an EMP or reduce it enough to not damage? For they do shield against EMP's in the military designs. Perhaps they us multiple layers with polarised capacitors as I mention in my previous post to this? These are rhetorical questions. I don't expect you to know the answers. Anyhow I hope some are inspired to come up with better shields. Cheers.
Excellent video and presentation 🙂 I've been freaking out over a possible CME and/or EMP... I recently received a "Pacemaker". I've been scratching my head on how to protect it. If it fries, I'm history... I've been instructed, by the Doctors, to avoid contact with "Welding Machines" and other EMF sources, such as High voltage Transmission lines, as they can mess up my device. To add some protective clothing and/or an EMP, EMF and/or CME proof shelter, like a Faraday Cage of some sort. I found a Filtering material, on Amazon, that is described as filtering 95% of most frequencies... I'm planning to make a tent of sorts that I can get into, in the event of a serious CME or EMP, etc. On the funny side, if the material Fails, I don't think I'll be in any condition to get my money back... lol Thanks for sharing this information... I'm going to get that book... Not just for something to read but because I NEED it... 🙂
great video. I have the same set up as yours however when i tested with cell phone and two way radio it completely blocked it. the only difference i did was I used copper tape around the seams and rim.
Dumb question- if am EMP can damage cell towers, HOW is an undamaged cell phone in the faraday cage going to work AFTER you take the working cell phone and TRY to call someone? Asking for everyone who isn't thinking about the dynamics of EMP or even CME's.
I think the big problem with your faraday cage is that the lid doesn't make electrical contact all the way around. What you have is a cage with large slots where the lid doesn't make contact. You need to have electrical conductivity all around the cage with only the tiniest gaps as the high frequency energy of a nuclear induced EMP will be very high, so the gap must be correspondingly small. We need an economical method of having a continuous faraday cage with continuous conduction. Electrical enclosures use conductive gaskets at the edges.
Is EMP able to do anything to the electrical system in the human or animal body? We are made up of much electricity and water. I am just wondering what effects EMP may have on the human body or brain. Thank you for the video, it is very much good help. How long must you wait to open the faraday cage after an EMP before it's safe?
trans and comms such as phones will be fried durring shtf it will restart to coding depending on which carriers you use your comm may ring longer or shorter but verbal communication will be impossible
your idea that the charge well be induced inside from outside the can is bull. Electric charges move on the outside of the conductor only so does the emf , that is why the can needs to be grounded.
trying to find out if you could use the inside of a car as a faraday cage? i know it protects against lightning but not sure about EMP... a car is basically a faraday cage as long as the windows are up right? I know the engine compartment is open on the bottom so the car has no chance of running again just curious about say throwing all your electronic devices in the car... like a microwave oven only bigger?
,,,,,,,, Sorry I disagree with you . Regarding small frequencies allowed to get though. Not all EMPs, are created equal. Don't forget. Weapons grade EMPs created by high altitude nuclear detonations will cause , multiple massive large electrical disruptions . Similar to multiple lighting strikes. Millions of Volts of Electricity not frequencies.
Aluminum will not Shield an EMP. You need a ferrous metal, ferrous means iron-containing, steel has iron in it. Stainless steel has chromium in it, that displaces the iron depending on the percentage of the chromium. If your stainless steel is attracted by a magnet, then you have enough iron in it to shield from an EMP.
False. Aluminium is an excellent faraday material. Copper is not ferrous and is also an excellent faraday material. An emp induces current by lens law. Not a magnetic field.
If all you have is a couple cell phones to protect, get a new paint can. Place the phones in a cardboard box and then in the paint can. Don't forget the charger too. Place lid on the can and step on the top to seal the can. Dunno why people want to save cell phones as the towers and grid would be destroyed, but no biggie. Best thing is to put boxed rechargeable batteries and charger in the container. Solar panels (disconnected ones) are usually immune to EMP and such so no need to enclose them. Your microwave is USELESS as emp protection. It is not sealed around the door. Fridge is useless too. On that small can with handle - you still need to tape around the lid after the lid is installed. And where the hinges attach to the can (inside and outside if you can). None of the DIY cages will protect squat if you are anywhere near ground zero.
that being so, still should go for a box that can totally block your fone. My tin can box can block phone signals as well as radio frequencies up to 107mHz being the highest available FM frequency there is. an EMP has a frequency 15-100mHz while CME 16-40mHz (based on online research). it cannot block my UHF radio as it it operates at a frequency of 400-460mHz. I keep my uhf/vhf transceiver in the tin can, although frequencies over 400 mHz seep in/out, if something detonates much stronger and fries my tech in there I have even bigger problems to deal with, like being dead.
The "bigger problems" are what Preppers prepare for. :) As I said, the author of this book says that you're not trying to block every decibel of every signal, but rather, lessen the strength of the signal so its no longer damaging. That being said, any less signal is better!
Could be a bad signal in their location, a nicer cell phone, or many other factors. We’re not trying to block all radio, we’re trying to block damaging radio.
I'm very concerned about an EMP. I have a stainless steel plate and screws in my leg. Can't really find any information as to what my fate would be in the case of an EMP.
its like an antenna booster. its why elevators get cel signals better when inside even if signal is low outside said elevator. like how your jaw bone extends range on car remote
So does a faraday cage reduce the radiation from a phone if I put one inside?cuz I live in a small room and I dont want to get so muvh radiation and get my health affected
Home preparedness is always a good thing, it is better to have it and not need it than to need it and not have it...perfect example something so miniscule like a bandaid, have you ever needed one and couldn't find one?
@@lrnselfrelianceI'm watching videos about Faraday cages because my utility company is requiring me to let them install a smart meter on my home. It's not that I am making any extraordinary claims about the radiation, but it would be nice to protect myself from it nonetheless. I'm wondering how much protection I would get if I just hung some aluminum screen on my wall where the meter is. The meter is on the exterior of the house outside of a bedroom. And if I were to hang a square of aluminum screen on the wall inside the bedroom, would that block most of the radiation? I'm thinking of a square of screen maybe about 5 ft by 5 ft or so. The siding of the house is made of stucco, by the way. I don't know if perhaps that helps protect from the radiation, does it? It has also come to my attention that my cell phone gives off more radiation than I thought. I'm looking into what can be done about that.
So you've read some, and know little. You must learn why things will work or not, like old cars. A generator! It'll run, new alt. Style will not work. New with and onboard comp. It'll be shot. So you've got enough information to be very missleading. Not to blame u, just can't broadly interpret what u read as true until you know the Why's.
An EMP will fry any wire over 6 inches in length. With cell phone who you gonna call? Phones don't call direct. They relay through towers that will be fried.
Is this the only source that you have this book? I'm really scared. I just woke up to this all. Do a video on all kinds of sources for people to learn by, please.
Have you tried calling the phone when youre further out of range? When i cover my wifi router you can still get wifi in the same room but there is less or no signal elsewhere in the house
Faraday cages attenuate (reduce) RF energy. The better the Faraday cage the more the RF energy will be attenuated. Garbage cans do not work well as Faraday cages. They are made of low conductivity metal. Typically tin. Line it with a few layers of aluminum foil and electrically seal the lid connection and other seams. Should improve effectiveness significantly.
Forgot to add, zinc plating oxidizes quite easily, the oxide coating protects the steel from rust but it is also an insulator of sorts. Try hitting the inside of the lid with some 0000 steel wool as well as the lip of the can before you place the lid on again. Don't put excessive pressure when you rub it. Just enough to bring out a slight shine. You could also try bonding some 1" wide tinned braided wire ,available from most any Amateur radio supply shop, to the lid and side of the can. You could try rosin core solder but acid core will work best. Steel wool the areas before soldering and if you use acid core solder try neutralizing the flux with a baking soda/water mixture rinsing with clear water. Dry with a hair dryer and spray on some paint to protect the solder joint.
The vehicle tests were done years ago. Modern cars have much more electronics in them than those 80s and 90s era cars/trucks. Do you have any new data?
So basically it is a copper lining and magnet attack, so when two meets it creates a magnetic field that is opposite which rebel other electric fields outside? So, in one part you say it reduces the electricity but not stop. That is one part or you are typing the whole Faraday Cage that reduces the electricity field, so it doesn't stop completely. Or you mean base on metal alone it reduces the electric field, but the other part with inner that is copper like which interact magnet attract which causes opposite magnet field to the opposite so it stops completely? So, magnet field is important to stop electricity as magnet field is a barrier but different barrier that is magnet is magnet field as one barrier to copper as another when two magnet field meets in opposite way it creates a third magnet field barrier as a lining so it stops or reduces electricity field.
See but I had the same problem And I freaking worked N worked for about 4 hours and I got zero service with zero calls zero wifi etc. you can achieve zero . I just did this this weekend. With enough work and idk I took a green coated wire striped it about inch pushed that into the ground then connected the rest inside the bucket and once I did that, that was when I achieved Total zero service and calls. I'm not sure if grounding it helped or not but I did it and when I did I finally got total zero service. Lots of aluminum tape and a bit of foil that's what I used with my metal can and lid.
A couple of ppl I know had dreams of world Chaos. And i thought it strange when my coworker told me during this crisis she try to make a phone call on her cell to her mom, but for some reason the number wont go through and the cell number she put in was jamming up and not corresponding like it should. And another one is that a friend mention hiding out in an old abandon house in the country. Windows all covered in foil and the only light source they had was parents old standing electric lamps from the early 90s. mind you these ppl are not end of the world preppers or christians. So for me i am just trying to make sense of it all and be prepared anyways. peace and love
An EMP blast is very broadband including covering the cellphone spectrum. A cellphone test will only be on one frequency pair, receive and transmit. If the Faraday cage will allow the cellphone through it will allow the rest of the spectrum through as well.
It will allow much of the spectrum through, but it will block most of the decibels. We're trying to block damaging radio waves (think of them as loud), not all radio waves (total silence).

We were about five miles from a VHF low television station (ch4)and about a mile from a local high rise building with multiple high power paging transmitters and could not receive their signal inside the cage. Don't bother these cages started from 3K$ and the sky the limit depending on size, screened panels, isolation panels for electrical inputs, lighting options.

Wow! Awesome contextual info. Cheers
Thank you very much for your, informative industry backed information. Nothing against this guy's channel.But even from an educational point of view. His info didn't add up.

@@tonymontalban5603 One can read a book and still not understand it. He was using terms, I bet, he could not explain to someone else correctly.
I was just going to comment that Faraday cages must be grounded, it's not optional. Then I saw your more knowledgeable comment. Thank You!
I have a hard time believing that modern cars will not fail from a short waved EMP burst. They have so many interdependent components if one fails the whole car stops working.
Ik right if you pee on one wrong it needs a reflash at the dealer
It'll crank back up.
Solar flares will eventually lead us back to using the very basic combustion engine technology..... Like a 2 stroke motorcross bike as the "new transportation" to get around 👍
If the leaders of the world don’t recognize that they are gonna ruin the world then we all gonna be screwed and none of that will matter
All modern cars use high energy ignition systems. The electronics in the car must be protected from the EMP generated during each spark.
I did a lot of work on the Mill EMP protected PCs, they were well sealed, and nothing, not even 1 seam was left open, 2 layers of stainless steal in most places, special metal gaskets, lots and lots of screws to insure proper mating of parts. If the relatively week cell signal can get into your can, what do you think the massive amount of energy from an EMP/CME will do?
Best bet use the metal duct on every rivet, seam, and opening on the can, use nesting 2-3 layers deep. The foil tape is like $22 for 50 yards, Cheap when I look at 3 radios, 3 high dollar flashlights, 3 GPS units, 3 Red Dots and other electronics. Easy to open a razor knife on a string tied to the lid.
Do you need this? Only you can decide but, if your going to do it, do it right.
While I believe the RF spectrum of frequencies can vary....in a properly placed nuclear explosion you could have EMP approaching or exceeding 50,000 volts in the pulse.. It will pass through metal with as little as 2% attenuation. Finding electronic devices inside and frying them. Cell phone demos are miniscule amount of RF energy. The ECM in cars/trucks will also take this 50KV pulse and many...many will be damaged. The ECM regulates fuel flow, spark, timing and many other functions to keep your vehicle running. If your vehicle is out of the pulse damage maximum then your damage may not be critical. My suggestion save your money building ineffective Faraday cages put it towards a bicycle or a horse. Get a Coleman Lantern because there is a good chance all LED flashlights could be toast also. Put money into food/water/supplies to tide you over for.a year or more. Own a gun you may need it for protection as well as food. I have lived long enough to remember living from well water and using an outhouse. We can get by without cell phones and the push button world we live in. Plan a plan and work your plan.
Will cell phone towers be fried? And if so, forget internet and a network to connect to with your laptops and cell phones.
Jay_J Jacobsen no they won't. Thats because they are over 100 feet in the air. If you believe that I can sell you on anything.
I'm thinking phones would be great to keep for media, music or movies etc, but flashlights are great. I'm gonna buy some lanterns though, great idea.
You forgetting something, like he said it's for dampening the effects, so if you are not that close to ground zero , but some reduction may save your devices.
Yes, and while on a " somewhat " related topic, the entire " 5g " used as a directed energy Weapon System, There will be nothing outside of a very deep Underground facility, as far away from the emitting devices as possible, to save a person from its effect. While i understand it is a " debated " topic, the entire concept of a Directed Energy weapon, more devastating and pervasive than an EMP, is a real possibility. And out of all massive, Humanity devastating weapons, with no loss of infrastructure.... Yeah, microwave attacks in the Ghz range is the MOST ideal.
It’s 2021, I have a faraday bag that does not allow a cell signal to ring my phone. Bluetooth doesn’t work in either direction even with only a fraction of an inch between two paired devices, one inside and one outside. The same is true of wifi/hotspots.
I’m guessing physics has not changed in five years but I’m pretty sure there is something amiss with your cage.
Still I appreciate the time and effort to produce this video!
Stay safe and healthy!
Put some steel wool around the top of your cans instead of tape that the lid folds the wool over and forms a shield around the top. Now you can open it without destroying the shield like with tape. Also for more protection that is really needed is get a couple sizes bigger can and put the small can inside it.
I get people wanna save their stuff.. But why save your phone? Who the hell are you gonna call? There probably won't be any working towers for phone.. Let alone internet
Get lanterns.... Get food.. Water..etc
Photos, but you could also save them on a hard drive. Then again, would be nice to actually be able to look at them on a screen
SD Cards slots filled with tons of audio, video, and ebooks regarding education & survival information.
6 years later and we're still here. But I'm still making one.
I'm in the process of making two emp cans, and your covering the handle brackets prompted me to check on their connection to the lid. I turned the lid upside down and filled it with water. Yep, it leaked! So the top does indeed need more attention!
I placed a rubber trashcan with lid into my galvanized steel can, with wadded paper and Great Stuff foam to keep the rubber trashcan floating within the large steel can. I duct (cloth type, non-metallic) taped all openings on the lid of the rubber trashcan, but did NOT duct tape the edges of the rubber lid when placing it down tightly. I then set my phone inside, ready for normal calling etc. Then I put the rubber lid on tight, laid a towel on top as a spacer to help the metal can lid hold the rubber can lid down tightly, and put the metal lid on tightly. Then i used metal foil 2 inch HVAC duct tape (about $10 a longggg roll at HD or Lowe's) to wrap around the lid of the metal can, to completely close it. I also taped securely over the little holes where the can handles and the lid handle are, to close them on up.
My first cell phone test was WITHOUT this metal taping.........and it was a wash........I could hear my phone inside ringing when I called it with my wife's phone. FAIL !!!
So I find the metal foil tape, put my phone in, close her up and tape her up as described above. PERFECTO! NO ringing at all.
Now the proof in the pudding: After slitting the tape, opening up the Faraday Cage, and retrieving my phone.......I take it and check for recent phone calls and texts, and there are none.........but about 2 1/2 minutes later the phone starts beeping with phone call and text updates coming in. Similar to how you have your phone turned off, turn it on, and soon the signals catch up with you........ only my phone was on the entire time, the signals just could not get to it within the Faraday cage.
So next I will be testing it with walkie talkies to check other wave frquencies.
The somewhat tedious part is having to retape it every time you open it up..........and the limited space, if you want to do more than just phones, cameras, walkie talkies and a old laptop or two.
So I'm anxious to find an old heavy duty storage locker like this guy did in his other video, which he has set up to be able to just open the doors and retrieve tools and electronics, then close the door and be good to go.........
With that crazy Rocket Man over there, we should ALL be taking greater measures to protect ourselves.
Throw your old laptops into your cages, too.........they just might become the backbone of a new world after all our good gear gets fried in an EMP/Solar event.
You can stop the signals to the phone if you place a metallic cloth covered foam gasket around the inside of the lid of the can. The problem is that higher frequencies can get through very small gaps between the sides of the can and the lid. You want to do your best to reduce the signal levels by 50 decibels or more across the range of frequencies. Without proper sealing between the can and lid you’re only getting about 15 decibel reduction in the upper frequencies.
I've been gathering emergency kits, not just based on emps or nuclear war etc, when things like the pandemic hit, it's good to be prepared. you just never know what could happen. being complacent in life isn't good and so many of us have gotten that way because we don't want to believe or even think about things going seriously bad. ignorance isn't always bliss.
I have just started learning how to make one, started out with just a ziplock bag, one I saved from light strips packaging and it's silver. heard it protects electronics to a certain degree when it's being shipped I guess... but I used copper tape and made sure it was completely covered , it's sealed with it all around and a little bit on the inside of lip of the bag. i did use my phone to test it, both withy regular cell service, Bluetooth and wifi. I had my Bluetooth speaker playing music from my cell and right when I zipped up the bag, it quit. made sure my ringer was cranked up and had my friend call me. from her end I heard it ring a couple times then it went straight to voicemail, my phone didn't ring itself. taking it out for the bag I noticed wifi was gone and LTE was used, but shortly after seeing that the wifi did come back. them I got my notifications of a missed call lol. so my device is still reachable kinda... I have to gain a better understanding about cellular service etc but mostly I did this to see what my google nest mini does along with the smart devices I have integrated to do certain things when I leave the house as I do have presence sensing turned on.
be good to add a crank radio that has solar, uses a lithium battery or regular batteries to the cage thing I think. just in case. maybe SD cards loaded with your precious podcasts and other videos, music... a kindle lol. idk. it's all ingesting though and it should be the last thing to do when you are doing prep prep like this but good idea to take the time to learn about it while early prepping for when SHTF
Gosh, this video aged so well, tyvm Sir!
What would have been nice, to us who know nothing much about EMP, is what would be affected without a Faraday Cage, ie: batteries in storage, turned off electronics, etc, and this would only take a minute or two to give a short summary. That would have given us a perspective about the effects of EMP so we can better understand the value of the Faraday Cage.
I believe the rule of thumb is, “anything with a chip.”
Stainless steel is a very poor conductor and a proper Faraday cage needs to be made from a highly conductive material. A copper can/mesh will block the cell signal. Your steel can is not able to effectively distribute the electric charge. Essentially, that’s not a Faraday cage, it’s a storage bin.
Wrap it in a double foil it it dosen't ring, it goes to voice mail
Consider that the amplitude from an EMP or solar flare is going to be a LOT stronger than radio or cell phone signals. If you're still getting through with those, you might want to quadruple or quintuple your protection.
Install a conducting gasket in your can and stop the rim acting as an antenna. The Dr. whose book you referenced proved that without the conductive gasket and he recommends several different types for ammo cans or garbage cans you lose a significant amount of DB reduction. I have the exact same can you have I used copper tape at the handle to secure that gap and tested it with cell phone and ham radio both with and without the gasket, but the gasket would stop cell phone and ham walkie-talkie communications completely. Your mileage may vary.
That trash can is NOT a Faraday cage. Partial shielding only. The lid’s not making a good connection.
His book is WRONG. It is mis information to convince the GULLIBLES they are safe.
Start with GROUNDING EVERYTHING to Earth. Home plumbing is NOT safe. 6 feet of copper rod is safe.😊
Have a neighbor who thinks his garbage can makes his Ham Radio SAFE. I laugh and walk away.
If we get attacked by EMP, it will be so intense, even ungrounded Faraday cages will FAIL to protect contents. In the Military we shield using ALL grounded, with TRIPLE redundancy. Good luck, disregard this utuber who knows only fairy tales !
I see you did this 7 years ago, things are way different now. I think everyone should have a faraday cage now!
An effective Faraday cage is a good thing to have. The problem though is that there are too many misconceptions and flawed information about them. Even this video about misconceptions is a misconception gold mine.
Some effective Faraday cage critical keys.
1) Must be electrically sealed. Even very small gaps will leak RF energy. The larger the gap. The longer the wavelength (lower the frequency) that gets leaked.
2) Use the most electrically conductive material practical. Not all metals have the same level of electrical conductivity.
1. Silver (best but cost prohibitive)
2. Copper (very good, expensive but affordable and available)
3. Gold (pretty good but very cost prohibitive)
4. Aluminum (probably the most practical)
5. Steel, iron and tin are further down the list. Line such containers with several layers of aluminum foil.
Aluminum foil lined containers make pretty good Faraday cages if they are electrically sealed effectively (several continuous layers; any overlaying of seams must be by a significant amount).
If electronic devices inside a Faraday cage receives a signal. Then it is not an effective Faraday cage and will not protect electronic devices from an EMP.
A shoe box that is well lined with aluminum foil and electrically sealed well can be a good Faraday cage.
If the can is welded at seams then anything more can add nothing. Furthermore, the aluminum tape has an adhesive backing which may actually insulate, rather than add any conductivity.
You touched the can while the call was made, and a human body emplifies wave signal by a factor of 10, that's why it worked.
Several of the studies are showing that even if a vehicle quits working after an EMP weapon, for a lot of the newer vehicles, they believe all that would be needed is to disconnect the battery then reconnect it to reset the vehicles sensors and most cars will run. I have been trying to tell people about this for years, but everyone believes that all vehicles will quit working and we will be in the stone-age after an EMP.
I use several Faraday cages similar to yours, yet I have mine layered for additional protection at different frequencies. First I use a sealed aluminum foil covered box to store my important electronics in. Then I use a copper mesh material to wrap the aluminum foil box and seal it with copper tape. Then that is heat sealed inside an EMP bag, then the bag is placed in a galvanized can similar to the one you have there and is sealed with aluminum tape. I shouldn't have any problems after an EMP.
Personally, I believe that we will be hit with a Super-EMP weapon within the next year which will be blamed on either Iran or North Korea, but I don't think either of them will really have their finger on the trigger. I think that finger will be a lot closer to home than most people want to admit or believe.
The Clown In America are not to be trusted
WH6FQE - The Kilted Piper how can I call you if your cellphone doesn't ring. Damn dude your mother called last night and was wondering why you don't answer the phone. I'll pass it on to her. :(
Agreed. DE KG7STF
My Faraday cage doesn’t let phones ring when called. And cars made before ‘84 have a much better chance of running after an emp, the majority of pre 84 vehicles will still need to have things replaced like alternator and cylinoid and possibly battery, but with only 1 in 10,000 vehicles made after 84 even have a slight chance of operating!
If there a blast that kills cars and phone and electricity you probably aren’t going to be A live
I just put a 4g phone in a biscuit tin and it never even went to answer phone. Also, when I removed the lid there was no signal at all. You sure that's made of metal? If it is you need more ayers! Because I just used a simple biscuit tin and it worked.
I read cordless house phones are more powerful so tried that in the same tin and it rang. You need more layers I just watched another experiment where 3 metal containers like the one you use were put over a router 1 after the other whilst the signal was checked each time. It took all 3 till the signal was lowered considerably. But every time one was placed over it the signal dropped.
was it a flip/dumb phone? It was easy to make a Faraday bag for my brand-new dumb phone (won't ring), but using the same material, a smart phone did ring. The antennae for the dumb phones are far, far weaker.
Purchase a backup computer module for your car model, wrap in in a few layers of foil and keep it under the seat just in case. Also, surges "confuse" memory circuits. Disconnect the negative terminal fro the battery for 15 min, then reconnect. It might start up.
If the emp takes out small electronics, won't it take out electric grid, cell towers, etc? Seems foolish to worry about having a phone if towers are down, grid down (transformers made in China) so no power except solar. Regular generators need fuel....that will eventually run out.
Cell phones will certainly not be able to make calls. But, if the EMP does not destroy yours, you may be able to use anything you saved to it. Offline maps, videos, etc.
The effects of EMP can be increased in nuclear weapons, and those ideas are classified. The higher the yield, the lower the EMP, but there are ways to enhance the EMP effect regardless of yield. Studies were conducted in 1962 during Operation Fishbowl in the pacific, but they didn't understand the full effects then. Much of it remains classified.
That was when they knocked Hawaii and parts of Australia out.
get a can large enough to place your bug out pack with your items inside and place all inside the can, easy in easy out in a pinch!
+Michael Cockrum I've thought about that. But space is a bit of an issue. Would be very easy to use however
The anti static bag numbers are probably erroneous. The anti static bag's metal layer is so thin that the metal would likely melt and the plastic bag decay, under the current load and heating induced by a nuclear EMP. All tests we can run to check for shielding are at powers that are 5 to 6 orders of magnitude or more lower than power levels generated by a nuclear EMP.
Pretty sure the aluminum tape has non-conductive adhesive, so for this purpose you'd be better off with copper tape, which is used in electric guitar pickups.
nuclear missles do not fry all comms neither do coronal mass ejections but durring that time who will translate through common and temporal dilects durring the time of comms restoration
The Faraday Cage blocks electrostatic fields, not the electromagnetic fields from de cellphone
An Aluminum container will knock your signal down completely.
dude i got pissed when i could hear my phone in there. u got the same problem as me, conductive tape the gap where the lid touches the can and ur phone wont work anymore in there.
Great idea. The author of the book didn't say that was necessary, but it will certainly help.
the guy that wrote the book you quote from has a video about sealing the can with the conductive tape. I believe he said with that, there was an 80db drop in his testing.
+Digitalmanne good point. I have a larger faraday cage that I seal. It's nice to have a secondary cage for commonly used items.
Not if it doesn't work. It might soothe your little feelings, but it's useless if it doesn't work.
Use an ammo can. Tear out the rubber seal and use the tape.
I have an metal brief case I was thinking of storing my laptop in when i was not using it in case there was an EMP. I tried to call my phone and it of course failed to block it as yours did. But would it stop an EMP or reduce it enough to not damage? For they do shield against EMP's in the military designs. Perhaps they us multiple layers with polarised capacitors as I mention in my previous post to this? These are rhetorical questions. I don't expect you to know the answers. Anyhow I hope some are inspired to come up with better shields. Cheers.
Excellent video and presentation 🙂 I've been freaking out over a possible CME and/or EMP... I recently received a "Pacemaker". I've been scratching my head on how to protect it. If it fries, I'm history... I've been instructed, by the Doctors, to avoid contact with "Welding Machines" and other EMF sources, such as High voltage Transmission lines, as they can mess up my device. To add some protective clothing and/or an EMP, EMF and/or CME proof shelter, like a Faraday Cage of some sort. I found a Filtering material, on Amazon, that is described as filtering 95% of most frequencies... I'm planning to make a tent of sorts that I can get into, in the event of a serious CME or EMP, etc. On the funny side, if the material Fails, I don't think I'll be in any condition to get my money back... lol Thanks for sharing this information... I'm going to get that book... Not just for something to read but because I NEED it... 🙂
From what I’ve heard pacemakers are built with a high level of protection, which should be safe in a case of emp.
great video. I have the same set up as yours however when i tested with cell phone and two way radio it completely blocked it. the only difference i did was I used copper tape around the seams and rim.
It attenuates the rf, that’s why you still need a filter to protect the circuits
Posted seven years ago. I'm sure electric cars would be toast.
Ion like the way that book used the term 'anomaly' regarding what would happen from nuclear fall out
I like when he said 'a.. CORONAL MASS EJECTION from The SUN'
And all antique vehicles won’t be affected !
Should my truck not being used have a ground hooked to the metal frame. Interesting video Thanks
Dumb question- if am EMP can damage cell towers, HOW is an undamaged cell phone in the faraday cage going to work AFTER you take the working cell phone and TRY to call someone? Asking for everyone who isn't thinking about the dynamics of EMP or even CME's.
A cell phone without cell towers is useless. But, a smart phone loaded with maps/pdfs/etc can still be useful.
thank you for mentioning the big grounding myth, I have seen countless channels recommend extremely stupid and useless grounding methods
I think the big problem with your faraday cage is that the lid doesn't make electrical contact all the way around. What you have is a cage with large slots where the lid doesn't make contact. You need to have electrical conductivity all around the cage with only the tiniest gaps as the high frequency energy of a nuclear induced EMP will be very high, so the gap must be correspondingly small.
We need an economical method of having a continuous faraday cage with continuous conduction. Electrical enclosures use conductive gaskets at the edges.
Dr Bradley has recently done videos on conducting gaskets to solve this very problem. He sells them or you can buy the same ones elsewhere.
Thanks, checking it out now....
Good information! Just subbed but I see your last video was 4 months ago. Hope to see you continue.
YEAH MATE 5 RINGS MEANS I NEED THE WRENCH NOW YES MATE THAT SIZE
Is EMP able to do anything to the electrical system in the human or animal body? We are made up of much electricity and water. I am just wondering what effects EMP may have on the human body or brain. Thank you for the video, it is very much good help. How long must you wait to open the faraday cage after an EMP before it's safe?
trans and comms such as phones will be fried durring shtf it will restart to coding depending on which carriers you use your comm may ring longer or shorter but verbal communication will be impossible
There is also this as an E-book for free or pirateproxy: Handbook to Practical Disaster Preparednes - Dr. Arthur Bradley
There is always a download somewhere, but I prefer to support the creator (since I am one now :P)
Is this the reason I can't find a Faraday phone pouch that blocks cellphone calls?
your idea that the charge well be induced inside from outside the can is bull. Electric charges move on the
outside of the conductor only so does the emf , that is why the can needs to be grounded.
trying to find out if you could use the inside of a car as a faraday cage? i know it protects against lightning but not sure about EMP... a car is basically a faraday cage as long as the windows are up right? I know the engine compartment is open on the bottom so the car has no chance of running again just curious about say throwing all your electronic devices in the car... like a microwave oven only bigger?
Another misconception. That Al tape is completely unnecessary, unless you're trying to make it water proof..
I Believe it’s because your cell phone and radios have antennas
,,,,,,,, Sorry I disagree with you . Regarding small frequencies allowed to get though. Not all EMPs, are created equal. Don't forget. Weapons grade EMPs created by high altitude nuclear detonations will cause , multiple massive large electrical disruptions . Similar to multiple lighting strikes. Millions of Volts of Electricity not frequencies.
Aluminum will not Shield an EMP. You need a ferrous metal, ferrous means iron-containing, steel has iron in it. Stainless steel has chromium in it, that displaces the iron depending on the percentage of the chromium. If your stainless steel is attracted by a magnet, then you have enough iron in it to shield from an EMP.
False. Aluminium is an excellent faraday material. Copper is not ferrous and is also an excellent faraday material. An emp induces current by lens law. Not a magnetic field.
Yeah people always go to extremes about things. But the truth is always in the details and nuances.
vehicles with non electronic ignition may only have condensor blown in distributor so keep spares in faraday cage
With all these explanation still a lot of people won't understand that because lot ofpeople don't know about electronics.
If all you have is a couple cell phones to protect, get a new paint can. Place the phones in a cardboard box and then in the paint can. Don't forget the charger too.
Place lid on the can and step on the top to seal the can.
Dunno why people want to save cell phones as the towers and grid would be destroyed, but no biggie.
Best thing is to put boxed rechargeable batteries and charger in the container.
Solar panels (disconnected ones) are usually immune to EMP and such so no need to enclose them.
Your microwave is USELESS as emp protection. It is not sealed around the door. Fridge is useless too.
On that small can with handle - you still need to tape around the lid after the lid is installed.
And where the hinges attach to the can (inside and outside if you can).
None of the DIY cages will protect squat if you are anywhere near ground zero.
that being so, still should go for a box that can totally block your fone. My tin can box can block phone signals as well as radio frequencies up to 107mHz being the highest available FM frequency there is. an EMP has a frequency 15-100mHz while CME 16-40mHz (based on online research). it cannot block my UHF radio as it it operates at a frequency of 400-460mHz. I keep my uhf/vhf transceiver in the tin can, although frequencies over 400 mHz seep in/out, if something detonates much stronger and fries my tech in there I have even bigger problems to deal with, like being dead.
The "bigger problems" are what Preppers prepare for. :) As I said, the author of this book says that you're not trying to block every decibel of every signal, but rather, lessen the strength of the signal so its no longer damaging. That being said, any less signal is better!
If it's not supposed to completely block the cell phone signal, then why do so many people have this happen with their faraday cages?
Could be a bad signal in their location, a nicer cell phone, or many other factors. We’re not trying to block all radio, we’re trying to block damaging radio.
@@lrnselfreliance thanks for the quick reply!
I'm very concerned about an EMP. I have a stainless steel plate and screws in my leg. Can't really find any information as to what my fate would be in the case of an EMP.
I would guess it would be possible for them to get hot. That is a scary thing I have never thought!
I would guess that I could be electrocuted.
its like an antenna booster. its why elevators get cel signals better when inside even if signal is low outside said elevator. like how your jaw bone extends range on car remote
Super informative and very complete, Thanks! The microwave oven was a DUH moment for me :)
2024 and things seem much more likely that something like that will happen
So does a faraday cage reduce the radiation from a phone if I put one inside?cuz I live in a small room and I dont want to get so muvh radiation and get my health affected
This has been studied extensively. Mobile phone radiation has no effect on your health. So don't worry about it.
Can I use an old metal tin lunch box? Or those big metal cookies tin? TIA
It would work about as well as a trash can!
Have they done protection on the signal towers for cell service. If not, having a working cell phone wont do any good it the towers are out.
Home preparedness is always a good thing, it is better to have it and not need it than to need it and not have it...perfect example something so miniscule like a bandaid, have you ever needed one and couldn't find one?
How about just putting things inside of an old microwave that you don't use anymore? Wouldn't that work as a faraday cage?
It might. But they are tuned for microwave frequencies, I would worry the EMP could have a broader range of frequencies and could slip past.
@@lrnselfrelianceI'm watching videos about Faraday cages because my utility company is requiring me to let them install a smart meter on my home. It's not that I am making any extraordinary claims about the radiation, but it would be nice to protect myself from it nonetheless.
I'm wondering how much protection I would get if I just hung some aluminum screen on my wall where the meter is. The meter is on the exterior of the house outside of a bedroom. And if I were to hang a square of aluminum screen on the wall inside the bedroom, would that block most of the radiation? I'm thinking of a square of screen maybe about 5 ft by 5 ft or so.
The siding of the house is made of stucco, by the way. I don't know if perhaps that helps protect from the radiation, does it?
It has also come to my attention that my cell phone gives off more radiation than I thought. I'm looking into what can be done about that.
So you've read some, and know little. You must learn why things will work or not, like old cars. A generator! It'll run, new alt. Style will not work. New with and onboard comp. It'll be shot. So you've got enough information to be very missleading. Not to blame u, just can't broadly interpret what u read as true until you know the Why's.
Do same test with unplugged microwave oven
I line the cans with contractors trash bags after the cardboard is in.
The word you are looking for is: Attenuated or Attenuation.
An EMP will fry any wire over 6 inches in length. With cell phone who you gonna call? Phones don't call direct. They relay through towers that will be fried.
Is this the only source that you have this book? I'm really scared. I just woke up to this all. Do a video on all kinds of sources for people to learn by, please.
it will send and receive calls or messages like one call means move two calls means stay
Have you tried calling the phone when youre further out of range? When i cover my wifi router you can still get wifi in the same room but there is less or no signal elsewhere in the house
Faraday cages attenuate (reduce) RF energy. The better the Faraday cage the more the RF energy will be attenuated. Garbage cans do not work well as Faraday cages. They are made of low conductivity metal. Typically tin. Line it with a few layers of aluminum foil and electrically seal the lid connection and other seams. Should improve effectiveness significantly.
Forgot to add, zinc plating oxidizes quite easily, the oxide coating protects the steel from rust but it is also an insulator of sorts. Try hitting the inside of the lid with some 0000 steel wool as well as the lip of the can before you place the lid on again. Don't put excessive pressure when you rub it. Just enough to bring out a slight shine. You could also try bonding some 1" wide tinned braided wire ,available from most any Amateur radio supply shop, to the lid and side of the can. You could try rosin core solder but acid core will work best. Steel wool the areas before soldering and if you use acid core solder try neutralizing the flux with a baking soda/water mixture rinsing with clear water. Dry with a hair dryer and spray on some paint to protect the solder joint.
The vehicle tests were done years ago. Modern cars have much more electronics in them than those 80s and 90s era cars/trucks. Do you have any new data?
What about dozens of nuclear warheads going off in the upper atmosphere in the span of 72 hours?
Thank you so much for explaining
So basically it is a copper lining and magnet attack, so when two meets it creates a magnetic field that is opposite which rebel other electric fields outside? So, in one part you say it reduces the electricity but not stop. That is one part or you are typing the whole Faraday Cage that reduces the electricity field, so it doesn't stop completely. Or you mean base on metal alone it reduces the electric field, but the other part with inner that is copper like which interact magnet attract which causes opposite magnet field to the opposite so it stops completely? So, magnet field is important to stop electricity as magnet field is a barrier but different barrier that is magnet is magnet field as one barrier to copper as another when two magnet field meets in opposite way it creates a third magnet field barrier as a lining so it stops or reduces electricity field.
I wrapped my phone on foil and it couldn't receive calls.
See but I had the same problem And I freaking worked N worked for about 4 hours and I got zero service with zero calls zero wifi etc. you can achieve zero . I just did this this weekend. With enough work and idk I took a green coated wire striped it about inch pushed that into the ground then connected the rest inside the bucket and once I did that, that was when I achieved Total zero service and calls. I'm not sure if grounding it helped or not but I did it and when I did I finally got total zero service. Lots of aluminum tape and a bit of foil that's what I used with my metal can and lid.
Wise info, thanks 🙏👍
After the EMP you remove all your gear to talk to others who experienced it when another EMP occurs???
That, and have the ability to turn on a flashlight. Or, radio to people miles away while everyone else has to walk.
I tape the seal around the lid with aluminum foil tape and the rivets around the handles and my cell phone gets zero signal.
I've gotten simple faraday fabric off amazon that totally blocks cell signals..... Careful, though, my aunt got some that wasn't quite as good.
A couple of ppl I know had dreams of world Chaos. And i thought it strange when my coworker told me during this crisis she try to make a phone call on her cell to her mom, but for some reason the number wont go through and the cell number she put in was jamming up and not corresponding like it should. And another one is that a friend mention hiding out in an old abandon house in the country. Windows all covered in foil and the only light source they had was parents old standing electric lamps from the early 90s. mind you these ppl are not end of the world preppers or christians. So for me i am just trying to make sense of it all and be prepared anyways. peace and love
If the Faraday cage doesn't work with a cellphone, it certainly will not work with a broadband EMP blast. This one will be useless.
It doesn't need to block all radio waves, just block enough to no longer be harmful.
An EMP blast is very broadband including covering the cellphone spectrum. A cellphone test will only be on one frequency pair, receive and transmit. If the Faraday cage will allow the cellphone through it will allow the rest of the spectrum through as well.
It will allow much of the spectrum through, but it will block most of the decibels. We're trying to block damaging radio waves (think of them as loud), not all radio waves (total silence).
He specifically addressed that. You somehow missed the whole point.
Depends on the yield of the weapon and the design of the bomb etc.
You have to seal the seals with aluminum tape and put aluminum foil under the lid.
