Pls continue what you're doing! You're a lifesaver and having a knowledge that is sensitive(hard to access) and rare is makes me feel lucky
I will have to check out these bags. I appreciate theses tests that you do. Helps one make a choice of what to buy.
Did you end up buying one? How do you like it?
Worlds best faraday bag reviewer. Thank you for your time spent on this!
Thank you!
I used the Faraday Defense material to make my own bags just like the NX bags. I used three layers of the materiel, used double tape between each layer, then used the faraday tape provided with the materiel to tape along the seam edges and the top, then roll the top down 3 times and attached Velcro to keep it closed. I used the Mission Darkness app to check the signals and all came back as zero. I have made a few different sizes and nest the smaller bags in bigger bags, essentially about 6-9 layers of shielding material for my smaller devices such as portable HAM radios, flashlights, battery chargers, a few small solar battery packs.
Excellent to see someone putting science behind these products.
well i got the nx and nx3 bags. theyre good quality. Ive tested my radios at 5 watts on the nx3 bags with another radio inside and the material blocks the rf even at 8 inch away on 2 meter 146.520 fm. I am happy with the purchase of the nx3 bags. I mentioned in my review for people to check out your videos.
Does size on the bag impact the effectiveness of the bag?
@@langw2461 No.
Thank you for the links in the description. I just found your channel and apparently the products from Faraday Defense are the genuine article. (It's difficult to find non-conflicting information). I also just read that metal sheets, of copper and aluminium for high frequencies and galvanized steel for low frequencies are much better than mesh/fabrics, etc. Supposedly, the seal is most important and possibly why some reviews on products like silent pocket are negative. In any case, thanks again!
A really nice set of Faraday bags!
I love your videos...they are always clear & concise...excellent testing methods...thank you Doctor!
Thanks for testing these bags. They definitely look good!
NEST-Z bags only claim 40 dB on the bag. Glad to see they exceed that. I plan to use them as secondary protection inside my EMP can.
As usual, solid work. Thank you.
Again, this is awesome. I learned a lot from your books, videos, website. Thank you.
Glad you like them!
very nice! I ordered the dri shield 3400 from you about 2 weeks ago. they work well. Im gonna get a few of these.
I made my own bags with the copper colored material, but I did mine with 3 layers. I am going to say it would probably work. I also have those zip lock bags and a dry bag that I use for spare computers and such,
Thank you so much for actually testing the effectiveness of these bags. Amazon Reviews are so deceiving. Competitors will actually pose as paid customers and put a bad review stating it provides no protection. They played a Netflix Video on their iPad and etc. Thank you for debunking this.
Been looking for a channel like this! Thanks
Dr. Arthur Bradley.... would you be able to do a comparison video between a lot of the faraday bags out today? I saw yours on here, but now there are at least 3 other major ones that are being advertised. Thank you
Howdy Doc. I'll have to check em out. Impressive stuff👍
Very helpful info. Thanks. Have you tested 1\4" steel mesh fence ( like from a local hardware store) If it was grounded ? What is your thought?
Hey Doc. I have a Bluetti AC200p. Is there a faraday bag large enough for it that you could recommend? Thanks for all your awesome videos.😌.
Faraday Defense small generator bag works you could fit 2 in there
Great testing and excellent products as well, thanks a bunch
This is the place to go for legit testing
The Nest-Z, is that level of protection adequate for an enemy's EMP pulse? Or is this version mainly for EMI/EMF? By the way, this was a very interesting video, thank you.
The Nest-Z is made for EMP protection, so it would work against an EMP. Where it differs from the other bags is that in its lower levels of attenuation, it doesn't have an anti-hacking/tracking ability.
thank you, they didnt have the NX3, but that is the one I went with. Thanks
Have you tried measuring the Silent Faraday Pocket Sleeve for Phones? I'd be curious to see how it compares to these products. Thank you for what you do.
I haven't tried it, sorry.
Outstanding, highly useful video. Thank you!
I own a few Mission Darkness bags and it's actually pretty scary the phone bag use to block out all signals but with the new Xfinity 6g wifi it zips through it like nothing
The Faraday Defense bags use an extra layer of shielding to provide higher blocking capabilities. I would give them a try!
Great testing! Thank you
Would love to see a higher frequency such as those from wireless devices. Something tells me I can search your other videos for that.
I couldn't do it until very recently because my test equipment didn't go up past 1 GHz. I now have some that will go to 6 GHz, so I should be able to take some measurements.
I can appreciate how thorough you were with the uniform method between the different products. But how did you conclude 500MHz would be representative for electronic gadget protection?
1) I would buy these bags to protect people scanning for my devices, so the test needs to be ran at each of those frequencies (that gadgets emit).
2) Given an EMP attack, 500MHz would likely be the least of my worries. Is there some way to scan a range of frequencies at X power?
*Nice RF room BTW. I want one!
It's a good question What you see when you run tests is that lower frequencies (in the 10's of MHz) are quite easy to block, but as you go up in frequency, the energy finds a way in through holes and seams. I picked 500 MHz as a representative frequency just for this video. When I run full shielding tests I go from 10 MHz to 1 GHz. It's important to know that frequencies below about 50 MHz have wavelengths that too long to couple into small electronics very efficiently. If we assume a conductor or PCB trace has to be 1/20 of a wavelength or longer to couple energy (a conservative estimate), that means the electronic item would need conductors that were about a foot long. Higher frequencies have shorter wavelengths that couple onto traces and wires more efficiently.
@@disasterprepper Fair enough. Thank you author of the video for the background explanation and taking the time to articulate that. I worked at Boeing as an ET for 27 years, and currently, a company who some of our products are on ISS- as a result, I've done EMI lab work for testing and certification. I look forward to seeing your past videos and what you have planned for the future, for a topic that's intriguing to me (as you).
PS: I like your portable. I presume (rhetoric question) a Rohde & Schwarz? Those aren't cheap for a reason.
@@OnHoldAt50 Thanks. Yes, the SA is Rohde and Schwarz, and yes, very expensive!
Just wondering, doesn’t you camera have microchips in it? Why doesn’t your pulse generator affect your camera?
I'm not generating an EMP. Rather, I'm generating a single carrier high-frequency wave at 500 MHz. The levels are large, but not so big as to damage the camera.
In a general sense, can we conclude that protection exceeding 80 dB may be sufficient to preserve sensitive electronic equipment from damage caused by an EMP/nuclear weapon in the atmosphere?
Have you tested any of the faraday defense Jacket cellphone/tablet/laptop bags? I own one and Im considering getting more. You fold the bag twice and seal the bag with velcro. Intrested how these compare to the faraday defense dry bag you tested in this video as the lining is the same, but the way its sealed is diffrent.
Would a passive conductive cell phone charger be safer that a plug in charger during a EMP EVENT?
Good video. I have a lot of the first bags with the zip top, that I was told are more effective if you double bag it. That is what I do, I hope it will work in bad times.
Yes, double bagging greatly increases shielding effectiveness.
I'm new to this kinda thing. Honest question: if you put a bag in another bag does it increase the protection?
It will increase the protection levels a little bit, but there is no need to double the higher quality bags. They already offer all the protection you will need.
@@disasterprepper ty! Do you have a vid talking about why you test at the frequencies you do?
can someone confirm if these bags are primarily good for blocking EMF/etc signal coming in to the device or also for coming *out* of the device? I heard somewhere these were good to use to put your device in overnight so you're not sleeping next to all the EMF/etc waves - but I can't find clear info confirming/elaborating on this or not.
My drone stuff tests higher than 80db. I’ll let you know if I have goggles or if my radio has lost rx from the quad. I’m testing at 1watt output.
What sort of shielding difference would be required to accommodate near field effects?
Well done. Is there a way to test wideband ideally 0hz-100ghz hahaha, ok maybe 3khz-2ghz
Great information and ty for sharing this. reposting in discord groups.
ZAH wassup?! Shouldn’t you be modding somewhere ? Just kidding. It is a great video.
@@PUREBLOOD-nj8gy hehehe, just luv Dr Bradley for explaining and showing why and how. I learn so much from him and like to pass the knowledge onto others. Alaska Prepper says it..reach one, teach one , repeat..
Yes ma’am he does say that and I see you are practicing that.👍🏻
Witch kind of faraday cage that can block all types of frequency? I mean everything!
A solid metal box would be needed, and even that wouldn't block really low frequencies. For that, you'd probably want mumetal, or other very high permeability materials. That's super expensive and not very practical.
Doc I have a home lab office with monitors that is 6' x 6' x 5' and interested in something that big and quick I can easily and quickly enclose everything with one wrapped cloth or container. And if there is an option to seal an entire section or office bedroom.
I love your channel... I have a question. Have you ever done a test where you put an item in "Dry shield bag" then put that bag in a larger "Dry Shield Bag" does that double the EMP protection??? PS. I love you channel
Layering like that comes close to adding in dB's. So two 50 layer bags layered might give you around 90 dB in total. Very helpful for getting very high levels of shielding.
@@disasterprepper Im not sure I understand? Layering them will add DB ??? I thought we wanted to reduce DB. Thanks sorry for all the questions.
@@bondscalper A dB (or decibel) is a measure of a ratio of two things. In this case, it is a measure of the signal outside to the signal inside the Faraday cage. 20 dB corresponds to a 90% reduction in field level, 40 dB to 99%, 60 dB to 99.9%, etc. The more dB of attenuation, the smaller the signal inside.
Witch is the best kind of faraday cage that can block every type of frequently and I mean everything!? Does anybody know?
Nice video. What type of material would work best under a mattress on the floor that receives a lot of RF from the neighbor below's Wifi router at night?
There are conductive cloths that might help for something like this. This is one of the best: disasterpreparer.com/product/emf-cloth/
That is a serious door lock!
Thank you for this information
Hello my friend how are you doing. Quick 2 questions for you if I may How's the survivalist audiobook coming on and are you going or have you done a walk around your emp office at all. I'd really love to see it. How it works what functionality you have stuff like.
I've made a little progress on the 13th Survivalist book, but not much yet. As for the walkaround, yeah, next time I make a video in the lab, I'll try to show folks around a bit.
@@disasterprepper that's brilliant. I Know it takes a lot of time to create a book so & good well written. I've still yet to find one thats equally as satisfying and none have came close. As for the walkaround I am looking forward to seeing this as I'm sure many people will too. Greatly appreciated 🙏.
Have you ever tried a metal trash can with a smaller plastic can inside to see if that works?
Got any long-term testing w/these bags? I've heard they degrade and begin to leak signals rather quickly.
These bags are built with 3 layers compared to the 2 layers that most other companies use. This allows them to block with higher strength, and last longer. The tough exterior gives the bags even more longevity. These will last quite a while.
Great video. Thank you. Keep it up
Doctor, I can’t see the “tower” bag in your labor day offerings?
Hello the. I wanted to no if I can make a faraday cage using an old chest freezer, I mean wrapping it up with 2 layers of aluminum foil. Thanks. Iv looked on the internet but found nothing when it comes to my inquiry. PS, if I can make a faraday cage using a fridge freezer would I have put aluminum foil on the inside as well of the out side as well. Thanks.
If you wrap it up fully, then sure, it'll work fine as a Faraday cage. But if you leave the door so that it can swing open, the seam around the door will likely compromise the Faraday cage unless you use conductive gasketing.
@@disasterprepper Well I'm going to cover the seal with a thin layer of foam then seal it with copper tape. Would I have to do the inside as well. The whole inside is covered in aluminum film.
Thank you for the video!
Hello, could you test what kind off radiation shielding a flexible cooling bag provides? I would like to use this for a small battery generator.(very cheap and wildly available) Sorry for the foor english.
Damn these bags are good.
I'm currently making a device out of CNC stainless steel(SUS316)to store some small USB and micro SD devices. It will be encased in 2mm thick stainless steel. The design will look like the shape of a cell phone, but sliced down in the middle much like a clam shell. The device would then be bolted on each corner with stainless steel screws. Do you think that device would be EMP proof?
Yes your box will work, even close to ground zero, but these bags won’t. There’s too much energy in a real EMP attack.
@@cpt.moroni3092 Even considering the slice down the middle(aka as a clamshell)?
@@cybersechs1368 your clamping it shut with bolts so it will make a metal on metal seal. Good idea and design.
@@cpt.moroni3092 Ok, thanks for the positive reply :-)
@@cpt.moroni3092 Why will these bags not work? I think you are not being honest, but I give the benefit of the doubt. So, can you be more specific? For example, if we layer bags into one another then that comes close to adding in dB's. So two 50 layer bags layered might give around 90 dB in total of protection, which would be equal to Level 4 EMP protection according to MIL-STD-188-125-1 guideline.
Where do the materials for these bags come from, and where are they made? How ironic/dubious it would be to use a product for protection whose origins are of the the very foreign country most likely to be the threat... just sayen.
I wish companies would start making these in light colors to protect against thermal damage from any outdoor sun exposure. These black bags will bake in the sun
So that huge body bag should hide the signal of chipped individuals...right???!!!??? LOL
It would be nice if they sold it in rolls. I need to cover the inside of my camper. 😁 👍👍
They actually do sell the material in rolls on their website. This link is for the fabric that is used inside the JACKETs. shop.faradaydefense.com/product/emf-rf-shielding-nickel-copper-rip-stop-fabric-roll-425-x-1-2/
@@disasterprepper
Thank you
How would this defend an EMP bomb?
Will a mylar bag work as a faraday bag?
Will these bags work against 5GHz signals from Wi-Fi routers?. In which it can absolutely block all Wi-Fi signals, and prevent my phone from connecting to it?
Does size on the bag impact the effectiveness of the bag?
No, it's more about the fabric and any openings.
I want to know is it will be different on 2.4GHz and 5GHz range
You'd need to test at those higher frequencies. Probably not as well.
Thnxs
Didn’t see the tower bags at there site
They are available at bit.ly/smallgeneratorbag
@@disasterprepper Thanks, probably more than I was wanting to spend.
But with 5g coming out soon won't that affect the quality of the faraday bags?
These bags work against 5G as well.
Subscribed 👍👍👍
Hi, how to protect solar panels please?
If they are connected, put broadband ferrites around their power wires (one per wire pair). If they're not connected, you can put them in a box and wrap with aluminum foil.
I have Mission Darkness bags don't get them they do not work what's even worse is sometimes they work sometimes they don't unbelievable
Nice door
Does normal Mylar bags work?
Normal Mylar bags will offer EMP protection, but not the tracking and signal-blocking that these bags offer.
These tests unfortunately do not take into consideration issues such as blocking cell signal, GPS signal, wifi, bluetooth etc, which means this is an incomplete test. I did a lot of research before purchasing my bags & personally wouldn't touch these based on these tests.
Which bags did you go for that will block cell towers and maps tracking as well as wifi and Bluetooth?
Sharing
GPS, WiFi??
These types of products usually do a good job of blocking both GPS (~1.2 GHz) and wifi (2.4 GHz/5 GHz).
@@disasterprepper I had to return one that I bought because it didn't block anything (silver colored pouch type). I bought another off eBay (2pcs Black Pouches $15) and they worked great.
What's the best bag you have ever tested?
What about bag inside a bag inside a bag please
Layered strategies work fantastic, essentially adding their dB protections.
oh come dude what about cellphone frequencies and power levels 500 mhz does not protect against intercept and oh sorry you gonna get paid 50 db is not good, its next to useless look up codename tempest sometime
Faraday products don't work.
Quit trying to make a fortune on each product you sell instead sell them for less and sell more also knowing that you be helping to save America as it is today
Hi Doc
Thanks for excellent tests and videos in general :-) I do not understand how the faraday defense bags, and the mission darkness bags have a damping og minimum 50 dB in the region (say 446 MHz) - and yet a 5 W Baofeng can not be blocked: In this video: ruclips.net/video/SZM2dugldPg/видео.html and in this ruclips.net/video/HuE_hv0bbyE/видео.html
But if I wrap my baofeng in 11 micron aluminium foil it completely blocks the signal.
