This only shows contacts can be made on a wet noodle when conditions are right. And a wet noodle would be about as good as this piece of junk. A simple dipole would blow it out of the water, no problem. Dismissed as virtually useless.
So a wet noodle can reach 14000km? Love to get my hands on one of these noodles. I also suggest you stop eating them as they are obviously making you a very angry human.
@@VE6SFX_HamRadioRookie It most certainly can, numps, under the right conditions. I reach much further with a simple resonate dipole than your feeble abortion. I have been doing antennas longer than you have been alive. Dismissed.
Dismissed? From my own channel? Wow. I am not sure what has angered you so much here. Regardless I am not here to debate you or try and change your mind. I am however concerned about how much anger you are putting into these comments. Please stop and spend the same effort on visiting with a loved one or a friend and have a coffee.
Back in 1970's at college, the ham radio club (VE3RSC) mounted a 14AVQ to the chain link fence, it worked great. Just looked the call up in QRZ, the college still holds the call! WOW.
Ditto on trying aluminum or copper foil self-adhesive tape on your fishing pole concept. Fishing poles are rigid surfaces so I don't see the flexibility of Faraday cloth is not a big plus. You mentioned possibly epoxying Faraday tape to the CF poles segments, I expect self-adhesive foil tape would be far easier. Look for tapes from 3M using their VHB (very high bond) adhesive or a 3M acrylic adhesive. 3M VHB double-sided tapes are used to bond large metal side panels onto vans so they can take a beating. They are good for a wide temperature range that you may find useful in Calgary (lived there for 3 years!). I checked and 3M sells some Al tapes at least. And, even if the foil tape you buy isn't 3M branded, when you look at the release paper layer it most often reads "3M".
You got this Ben. Being able to think outside the box is a result of truly understanding how something works, and you've done both. Here is my suggestion....Place an inductor over the joint so that when you rotate and change the capacitance, you have an adjustable trap. Make the inductor a fixed value (wire is ok) and wind it (glued to the outside) of a pipe, then place the assembly over the joint of the mast. The coil assembly should have conductive tape around the inside (each end) to make contact with the vertical tape part of the pole. Anyway, that's what vision popped into my head. I'm sure there are other ways to place the coil in parallel with the vertical wire / capacitor. I just want to see you sell a gazillion of these and become a household name. 73 OM Keep up the excellent work!
The things you're doing experimenting with Faraday tape and cloth is amazing. Keep up the great work. I keep meaning to order a fara-J and I will. Great job!
@@NVRMTmotionif you have multiple carbon fiber masts it might be good to try them all. Some epoxies do bad things to RF so you might have better results with some of them.
Very interesting. I love experimenting with ideas and hearing all the "experts" tell you it has to be ".......". My favorite is "it has to be resonant". Bah hahaha. I've laid random lengths of a variety of wire types on the ground an made 1000 mile contacts. Tried the same thing at a different place, 100's of miles away and it didn't work well. I've used a chain link fence as an antenna ..... eh, as a last resort. I have also attempted to use the fence as a counterpoise, and had better luck with no counterpoise. Tell me "you CAN'T do that" and I'll tell you "hold my lemonade". This hobby is about experimenting. There are so many variables to each situation. They only way to learn, is to try. The best way to learn is to do. What works unsatisfactory for one, may be totally satisfactory for another. Please keep up the great topics. I may be going into the garage and dig some stuff out today, thanks to your video!! For me a 107' EFHW run between the 2nd floor eve and a 15' COMPOSITE (thick wall) pole, that's stays put during the hurricanes, and my other vertical antenna, have allowed me to make over 16,000 contacts in 195 countries (DXCC entities) in the past 2 years. I seldom use more than 100 watts. Playing around and experimenting helps me learn where I can improve and ways that work for me and my situations. Good hams always promote. My momma always told me to stay away from negativity. It's been good advice. Great video!! Great energy! 73 -de KN1B
"I may be going into the garage and dig some stuff out today, thanks to your video!! " best comment I could get. Love that others are using this as a spark to create their own things!
By far, one of the best videos I have seen to date. I really want to try and build one. Thank you for making a common sense video, with brevity. New subscriber!!
Glad it was helpful! Yes it hurts how much I cut out of a video. There was literally 24min of talking head and build video when I started. But in the end it makes better content.
I've still got a couple rolls of copper tape sitting here from your appearance on Ham Radio Workbench. Still haven't had time to play. Now you've given me another project to play with.
That's a pretty clever way to get a stick in the air. I'm not a ham (yet), saving up some disposable $ before jumping in. I am a professional ether smith, a bit spoilt I guess, never had to experiment beyond implementation and commissioning. The performance confidence isn't left to chance when it's a commercial endeavour. A bit like the mechanic's car that's never fixed, the last thing I want to do in my leisure time is do my job....but having a fun job can lead to fun hobbies too in retirement. It will happen eventually. Great channel. The comments here are pretty high value too. Nice community. Everything radiates. 🖖
Found this through KM4ACK's weekly newsletter, glad I did! I bought one of these fishing poles years ago as a support for an ef antenna and I've heard of people coiling their EF wire around them to make a vertical. I like this idea even better. I'm going to get some of the tape and try it as well. Thanks for the idea! I subscribed to the email list, looking forward to seeing where this goes. My hope is to be able to fly with this at some point and not have to rely on stringing a wire somewhere on vacation and for POTA/SOTA operations.
Look up CCD antenna. Although they use resonate sections of wire capacitor wire capacitor there is alot you can learn. I posted a link but I think it was filtered out. Also at the end add a ring of tape to increase the capacitance.
Very Interesting. I'm sure some people will say you are crazy for trying stuff like this, but try away anyway please. I am very curious about this now. You are contributing very novel ideas to the ham radio community.
What do I know as a Technician whose never transmitted on any HF rig (though I'm studying for general).....what came to my mind was the conductive tape you are sticking onto the pole secitions----wouldn't it be awesome if it was embedded into the carbon fiber as the section was laid up? I've been around a lot of carbon fiber sea kayaks and they are often coated with a clear gel-coat. The conductive tape possible applied to the sections before clear coating? The clear coat's thickness would of course have to be accounted for in sizing the diameters of the nestling pipe sections. Then there's the thought of a carbon fiber tube that is only 95% complete....the other 5% being a metal strip filling the void and running the length of the tube. Regardless I think what you are doing is novel and genius. I hope it comes to fruition one way or another because someday I'm going to pass General and then (even though I have acreage and room for an EFHW) I'll want a vertical :) Something else. The SOTA boys (and girls) will love love love your mast that is also antenna!!
@@VE6SFX_HamRadioRookie Yeah I woke up thinking about your antenna? Why because I need a super quick rapid deploy vertical 20m or 40m. So scratching the sleep out of my eyes I thought of metallic paint. How thick is that conductive tape you have been applying to the pole(s)?
Aircraft control surface embed metal fabric into the carbon fabric layup to create a conductor to dissipate static electricity from the aircraft. Why wouldn't it work the other way?
This sounds like a cool, easy to use concept. I was already looking to test some faraday tape as an antenna, but to have a good long range when I visit my families 40 acres (with hill) would be awesome! Thanks for the video, will be subscribing and look forward to more.
So many possibilities. Wondering if the carbon fibre is necessary for the tape to make the capacitative coupling jump. If not, variant could be nesting plumbing PVC ducting of increasing diameter. (We have a 20m DIY antenna shootout coming up at one of my clubs and I was thinking of not going the traditional wire route but some sort of PVC self-sustaining foil tape approach, but contemplating base loading). Aside from regular quick-install for this antenna on a fixed basis, also coming to mind is using multiple of these for a phased array, eg. 3 or 5 elements, could even be possible in a SOTA context ...
In the end only one way to find out if it would work. Get some pvc and tape, as well as a LCR meter to get capacitance and this should answer the question. I may try this but it will be a while till I get there. If you do it I would love to hear the results
I certainly won't be throwing any crap your way! I'm an Extra-Class ham, and I love experimenting with "weird" antennas! I'd be interested in ANY results you get. In fact, I can't believe I'm saying this, but I haven't been on the air for several years (never thought I'd go that long), but I'm thinking about getting back into it just to try this out. Thanks for making me aware of this antenna. No joke, this is interesting, after seeing that you had a QSO 700 miles on 60W, on 10m band. (I know with a "good" antenna, others have gone farther with less power on different bands, not really sure what the record is on 10m band.) Frankly, I'm not interested in "setting distance records" except as a comparison number. But I am interested in discovering new properties, etc. Projection: I'd "predict" that twisting your pole segments (to vary the alignment of the conductive tape) will result in different length antennas, in increments of your pole segments. I know that you can vary the capacitance between plates by changing the alignment. 😮 Keep up the work, stay in touch! >>de ai4rv, Goose Creek, SC. 🤪 👍👍👍
I am so excited about this concept too! I have all the parts and will start playing with the idea. My squid pole is fiberglass. Will be interesting to see how that affects it. I'm south of you in WA state. Will watch for more.
This is so cool think you're really doing a great job please keep up the great work and I'll be looking forward to seeing how your product turns out if you put them out on the market for sale I'll definitely be purchasing one
That's pretty slick. Especially with it being so inexpensive to throw together. By the way, your amazon link to the poles is linking to the Faraday tape. Little duplication whoopsie there, lol.
You’re welcome. You got me thinking … any reason not to try conductive paint? I have a ton of the stuff that I use to shield the control cavities of electric guitars (I use EZ-Slide graphite paint). Heck, I could probably “fold (paint) it over” without affecting the telescoping function. Thoughts on that?
I have tried the conductive paint and yes it works. thing is that stuff is like 100.00 per oz. So it might be out of the range of most peoples wallet. However another has commented about using 'Defroster repair' paint. I am going to look into this for a less expensive solution.
Just some things to keep in mind: You can do a lot of tuning with capacitive coupling, but it just makes the electrical length shorter, not longer. That's why hams use an inductor on the base of their vertical antennas and tune it, because it takes what amounts to a 10 meter, quarter-wave, 15 meter, or 20 meter quarter-wave vertical and makes it electrically longer in order to hit the rest of the HF bands. Also, inductively coupling in one spot to a relatively poor conductor for loss testing is not the same thing as capacitively coupling to the entire length of the material, which is what your conductive tape is doing.
As always, Great job experimenting! I'm looking forward to seeing what becomes of this. If you need any testing assistance, please let me know, I have some tape here.
A neat trick for using a lightweight mast as your whip! Instead of a (somewhat) heavy stainless whip, or perhaps using a longer mast, you might get even better performance than, for example, the CHA MPAS lite.
In all honesty the 17' and 25' stainless whips weigh about the same. But min is much more robust and less likely to permanently deform and or fold over and break. Plus I have a 50' whip I am going to finalize testing on shortly :) That definately does not exist in stainless
I am excited to try this - thank you! Would you be willing to share how you got from the bolt at the end of the mast to an SO-239? I am new to this and would like it to be clean.
How does the cost of faraday tape compare to that of copper tape? It is sold cheaply for gardeners who want to keep out slugs. Slugs apparently hate copper.
They are about the same cost but the faraday tape has sone special properties that make this method work better than copper or al tape. I am slowly figuring out what that are.
This can be a revolutionary HOA antenna. Like many others, my house has a wood facia board running along the end of the roof. I had planned to use some eyelets and create a random wire antenna that would be reasonably well hidden. But this might even be better. Hiding the drop from the board to the window might pose a little problem. I wonder if I could extend the tape onto the stucco wall. Would it stick? Would painting over the tape affect it?
Absolutely you could extent it. I am not sure it would stick to a stucco wall but given how inexpensive the tape is, get some and try. If it does not work you can use it for many more things. Seriously I have rolls of this in my bug out bag for improvisation.
Definitely something to look into. I do have some conductive paints but they are prohibitively expensive. This stuff I had no idea existed and will look into it Thanks!
I like the idea of this antenna. this might be yet another way of providing people with an antenna for those with limited space as well. I don't know about restricted covenance, though.
Carbon fiber IS electrically conductive. I sanded the finish off a telescopic, attached a wire with a hose clamp, and made DX contacts. Use the carbon fiber pole AS the radiator.
@@TrekOnTheAir FWIW I have been using one naked with a antenna tuner and it works just fine. Soon Ill do a video on the SWR sweep. Here is a teaser 30% is below 3:1 between 3-60Mhz and 60% is below 5:1 on the rest. Its kinda crazy really. I have been doing Italy, Wales and South America from Calgary on SSB between 10-40m regularly. 6-10 thousand Km. On FT8 and WSPR I have 15 thousand Km
Have some spare tape and find out! Digital modes can be "hard" on antennas "power ratings". I determine my power ratings. I bought an "online", cheap vertical rated for 200W SSB and digital. After using it for several months for digital contacts (max 75W), I noticed the balun melted through the housing box. Found my weak point. I build a new box to hold a 2000W balun. The box included new wiring, connector, and screened vents. I used that antenna for years with SSB contacts using up to about 1200 watts. My point is "find out". Protect your radio(s), but give it a try. When it reaches the limit, fix the weak point. Love this hobby!! -73 de KN1B
Your antenna is similar in principle to an antenna published 20 years ago or more by the ARRl in the antenna compendium. The published ARRL antenna was a dipole interrupted in the arms by a series of capacitors. You could check their article and get hints for your experimentations.
Hey buddy, cool to see that you're into Ham Radio! We'll def have to try to hook-up on the air. I run a FTdx10 right now and picking up a FT-101 station this morning because everyone "needs" a boat anchor. Hope you're well!!
I have used the fiberglass version of these poles for several years with my RV HF radio. Have you tried feeding this antenna with a 9:1 balun. It works well for with a 33 ‘ wire strung inside a fiberglass squid pole. I like your idea, Eliminating having to string a wire inside the pole when setting up the antenna would be a time saver. the I’m going to order up some conductive tape and try it on the fiberglass pole I have. If it works as well as the wire does, I’ll let you know. One problem I have had to contend with is sections of the pole collapsing due to wind vibration. Plastic hose clamps, appropriately sized for the different sections work well, but it adds a bit to the set up time. I only use these if I’m setting up for a long duration, or wind is going to be a factor.
Cheers from a fellow ve6. I am va6gg in Edmonton. This is a really cool concept. Ignore the old farts saying it's all been done before. Maybe the idea was floated before but we didn't have cheap and easy access to things like light weight large telescoping poles and conductive tape at current prices. We couldn't get it all delivered in a few days to our door with a couple clicks. It's still a really great idea and quite practical now given how easy and cheap materials are compared to let's say, 35 years ago. If an antenna performs at least as good as a mono-band dipole, then you are laughing. I remember when a roll of conductive adhesive copper tape was 60 or 70 bucks. Now it's 10 for 3 times more. This conductive cloth tape is something that simply wasn't available to the consumer in the past. Keep the project rolling. I want to see what you come up with on this antenna. Multi-banding is definitely a direction you should explore. I think conceptually it should be fairly straight forward to accomplish, though you'd have to switch perhaps to a more resonant radiator design and find some way to key each section to fit together to achieve the correct radiator length for each band. Imagine if you could create this antenna but resonant so no tuner required. That right there would be about the coolest new antenna design since the DX commander. I think vertical antennas for HF amateur radio got a bad wrap for a long time and some smart creative people have brought them back into favor. They work amazingly well and don't require big, heavy, complicated and expensive antenna support structures along with the real estate to erect said antenna support structures.
Thank you for the encouragement! And agreed the world has changed. Hopefully the creative mindsets can bubble up again and not be suppressed buy the grumps
Yes it was but you can go into his video and he will explain it much better than I ever could. In the end the losses are still inconsequential. Thus this antenna working so well
Hi Rook! Very innovative concept...I'm building one (or two) now. I'll try copper tape instead of Faraday tape. Have the copper tape but do have yards of Faraday cloth which I'm testing for ground planes. The copper tape will have better conductivity although my tests on Faraday cloth show it's surprisingly good on that score. The practical impact of having a telescoping fiber pole that requires no wire is a move toward Occam's Razor in portable HF ops, IMHO. Looking forward to how you play this out. There's a Latin phrase for don't let the bastards get you down but I don't have time to look it up right now. You might suggest that viewers who get triggered by innovation "that shouldn't work" go watch some cat videos. The Smoking Ape can hook you up on some references, lol. 73 de K4FMH
I thought you were going to put the tape inside the pole, top to bottom so it hung loose inside which I figured was genius. But when you you put it on the outside I was even more impresseed. Is there nothing you can't invent with that tape :) I just bought a large amount of the material to use as a magic carpet but now I'm wondering is I can put an adhesive backing on it and laser cut some kind of coil / trap which could stick to the pole and is very repeatable and low profile. You are an inspiration to a 59yr old antenna engineer.
Interesting idea! Did you use a balun? I wonder if it would be possible to leave a 'tag' of the tape at the bottom end and connect that to a 4:1 or 9:1balun as would be used in a randon wire antenna?
No balun. And yes leaving a tag and alligator clip will work. I find the antenna performs quite well with no balun and the SWR is manageable by the atu-100
This is freaking WILD! If the antenna works collapsed, have you messed around with what can be done with it collapsed? Maybe collapse every other section (use zip ties) to keep the capacitive coupling from hopping around? I'm thinking about getting a 30 foot +/- (like 10 meters) tall antenna that works the 40 meter band. Does the tape work like an inverted V if you go up one side of the mast, across the top, then down the opposite side? I'm thinking maybe an 80 meter band antenna that's 30' +/- tall. Maybe run multiple strips of tape up the mast like a Faraday Cloth DX Commander? With a cloth groundplane? That all collapses and folds up? Sorry if I'm making you drink from a fire hose with all my questions. Too much beer turns me into an excited 6 year old with an engineering background. 😉
Totally understand the fire hose of ideas… appreciate your enthusiasm. Few things I’ve tried. And FWIW I can tune 40 and get this 80 with the 33’. There is magic in the faraday tape I cannot explain… yet.
Ok, this seems to me an exercise in learning, I mean, we all have to start somewhere I guess. If the goal is to set up a capacitive radiating dummy load, you're on track. But if your goal is to get on the air, just use a length of ware, a 9:1 unun, a tuner and get on the air.
FYI carbon on its own is a poor radiator but with the conductive tape it becomes a radiator. the ohmic resistance of just carbon is crap and for the most part is a dummy load. But when you add the tape it changes EVERYTHING.
How very exciting sir and was riveted to your video and experiment. I will be in anxious follower I'm kind of a Frankenstein antenna guy myself even though I'm just getting into the hobby. Most interesting for me was the coupling and adjustments that are possible by rotating or turning sections. And I wonder and plan to see if it is possible to achieve the same along the lines of a large telescoping whip antenna element as well. Thank you for your contributions and for experimenting it is awesome take care and 73s Adam (Festus, MO}
this terry guy did the exact same thing to me. saying i don't know shit. my idea works well and yours has a lot of potential. id like a collapsible 1/2 wave just for 10/11 if you get to production don't forget me.
Fascinating! of all the HAM video's I watch on here, this might very well be the most interesting since quite some time. I wonder if this concept could work as a EFHW on 80 to 10? Anyway, thanks! 73.
OMG, this is the coolest friggin' thing! Thanks for sharing. I must try this. Regarding carbon fibre, it's unfortunate that the ham world is filled with finger-wagging naysayers, but in my experience, these are all 'armchair hams' (a term which in their case is a tautology) whose only attempts at experimentation are in making stupid comments to YT videos, thus contributing not one whit to the hobby. Anyway, I love this kind of creative thinking; this is exactly what ham radio should be about. Cheers!
Very interesting concept, well explained, Thanks a lot. About these Aliexpress poles, I've bought one one these supposedly 13m long poles and it's hardly 10m long. Sams for you? Not sure it was from the same seller, but it does look familiar.
@@VE6SFX_HamRadioRookie I admittedly might have not counted the super-thin, unusable for anything last segment to measure 10.something meters long only. Yes, I did suspect too that all these offers were actually coming from the same seller. For long poles (10m up) the only alternatives are the much more expensive Spiderbeam and such poles, that are too thick at their base to fit into any ground anchor I could find and too heavy for me to bring them up on my own when extended and there's any wind blowing. I have a 12m one and I hardly ever use it, I work with these cheap fishing poles instead. EDIT for an extra question: do you think these really are made of carbon fiber and not just plain fiberglass? I have doubts.
"Yes", like you do think they're really made of carbon fiber? Well, OK, I really thought otherwise. I broke one at half its base segment on a windy day, they're kind of fragile. I get the idea of "no extra loading", but how to you apply that tape to a segment that's barely of 1 mm diameter? I'm curious
A very interesting concept but, as you say in the video, I would like to see a lot more work done on measurement off capacitance at the joints, loss and or gain, effect of flex in the antenna, and a whole bunch of modeling and experimentation. It could prove to be a fantastic design but it also could prove to be a money spinner for cheap Chinese manufacture producing low quality knockoffs.
Great idea, HRR! I will be signing up because I love the concept. Also love your logo. If you make stickers out of that, I’d love to trade with you for one. Thanks and 73, KB4ROY
Ok, I thought that it was all there. The antenna is extended in several shots, the counterpoise, the mount in the ground, do you want to see the coax going to my house? The mount etc is here: ruclips.net/video/96KtICkqXwQ/видео.htmlsi=myjLn6sesqrJy2wx&t=231 and the extended antenna is here: ruclips.net/video/96KtICkqXwQ/видео.htmlsi=SF2LmkBXbs8UG-YF&t=257
Am i missing something here? Why not just use a telescopic pole like any portable radio with it,s telescopic antenna. Just slide the antenna to its ressonant measurement.
If you mean just extend the carbon poles alone. They are quite resistive and do not work. They are effectively a dummy load. ruclips.net/user/shortstFA2LB3aKKQ . If you meant a stainless steel whip then I do not know of a 33' stainless extending whip existing anywhere or if it did it would be no where near as strong in a wind load
Yes there are aluminium masts that tall but they weigh a bit more than 1.5lbs I currently have a 50' up and testing it as well. I am gusessing that the weight is substantially more than the 4lb I have if it were made of aluminium.
It is also known as Faraday tape if you google it or search on amazon or ali express etc. This will bring the tape up in results. It is made from faraday cloth so it goes to say faraday tape is a reasonable assumption/
Great video, Ben! I should warn you though that you're dangerously fond of objective reality. All this insistence that the data your instruments and experience indicate beats the blind babble of conventional wisdom... that'll get you in trouble, OM. Ask me how I know. Anyway, awesome channel! I'll be back.
Receive aperture, yes. For TX, if you put 100W into a matched antenna, with a lossless matching circuit, and there is no part of the antenna that is getting hot, then 100W has to come out as RF. As the antenna gets smaller, it approaches the radiation patern of an isotropic antenna. Which is only a couple of dB down from a dipole. The difficulty with a small antenna relative to wavelengh is in actually achieving a lossless matching circuit and antenna with no lossy parts.
Easy peasy… ditch the paracord and get some heavy duty spectra line. You can get stuff with higher breaking strength than paracord. It’s in the fishing section of most sports stores. Anyhow it’s a fraction of the weight of other solutions
@@VE6SFX_HamRadioRookie Right you are. It's incredibly strong. I've used it as well as dyneema for my parafoil stunt kites. I think dyneema has to be sleeved to help it maintain strength for my application, but I sleeve my Spectra line anyway. Spectra line, when purchased for deep sea fishing and not kite flying, is cheaper and works great. I've used the methods for retaining 80% of the strength in a knot for years. Pull as hard as you want and when you're done, the tether pops apart as if you never pulled on it in the first place. Speaking of kites, I want to try a big delta kite to pull up a wire and use that as an antenna. It's stout enough to hoist up a simplex repeater. Thanks for this video! I like these affordable performer videos. :)
This only shows contacts can be made on a wet noodle when conditions are right. And a wet noodle would be about as good as this piece of junk. A simple dipole would blow it out of the water, no problem. Dismissed as virtually useless.

Cool idea. Many years ago, I used alarm window foil tape on PVC pipe and made antennas.
That's a great idea!
@@VE6SFX_HamRadioRookie you can make J-pole antennas with conductive copper tape on the back of eg duct tape or cardboard or whatever :)

Ditto on trying aluminum or copper foil self-adhesive tape on your fishing pole concept. Fishing poles are rigid surfaces so I don't see the flexibility of Faraday cloth is not a big plus. You mentioned possibly epoxying Faraday tape to the CF poles segments, I expect self-adhesive foil tape would be far easier. Look for tapes from 3M using their VHB (very high bond) adhesive or a 3M acrylic adhesive. 3M VHB double-sided tapes are used to bond large metal side panels onto vans so they can take a beating. They are good for a wide temperature range that you may find useful in Calgary (lived there for 3 years!). I checked and 3M sells some Al tapes at least. And, even if the foil tape you buy isn't 3M branded, when you look at the release paper layer it most often reads "3M".
You got this Ben. Being able to think outside the box is a result of truly understanding how something works, and you've done both. Here is my suggestion....Place an inductor over the joint so that when you rotate and change the capacitance, you have an adjustable trap. Make the inductor a fixed value (wire is ok) and wind it (glued to the outside) of a pipe, then place the assembly over the joint of the mast. The coil assembly should have conductive tape around the inside (each end) to make contact with the vertical tape part of the pole.
Anyway, that's what vision popped into my head. I'm sure there are other ways to place the coil in parallel with the vertical wire / capacitor.
I just want to see you sell a gazillion of these and become a household name. 73 OM Keep up the excellent work!

wow, what a wonderful idea. Thanks so much for sharing your continued experimenting. This certainly keeps the hobby interesting, exciting and fun.
Thank you very much!
Very interesting. I love experimenting with ideas and hearing all the "experts" tell you it has to be ".......". My favorite is "it has to be resonant". Bah hahaha. I've laid random lengths of a variety of wire types on the ground an made 1000 mile contacts. Tried the same thing at a different place, 100's of miles away and it didn't work well. I've used a chain link fence as an antenna ..... eh, as a last resort. I have also attempted to use the fence as a counterpoise, and had better luck with no counterpoise. Tell me "you CAN'T do that" and I'll tell you "hold my lemonade". This hobby is about experimenting. There are so many variables to each situation. They only way to learn, is to try. The best way to learn is to do. What works unsatisfactory for one, may be totally satisfactory for another. Please keep up the great topics. I may be going into the garage and dig some stuff out today, thanks to your video!! For me a 107' EFHW run between the 2nd floor eve and a 15' COMPOSITE (thick wall) pole, that's stays put during the hurricanes, and my other vertical antenna, have allowed me to make over 16,000 contacts in 195 countries (DXCC entities) in the past 2 years. I seldom use more than 100 watts. Playing around and experimenting helps me learn where I can improve and ways that work for me and my situations. Good hams always promote. My momma always told me to stay away from negativity. It's been good advice. Great video!! Great energy! 73 -de KN1B
"I may be going into the garage and dig some stuff out today, thanks to your video!! " best comment I could get. Love that others are using this as a spark to create their own things!

Welcome aboard! I can't wait to see where I go with this too. :)
You are making excellent videos with progressive content. Keep up the great work
I appreciate that!
That's a pretty clever way to get a stick in the air.
I'm not a ham (yet), saving up some disposable $ before jumping in. I am a professional ether smith, a bit spoilt I guess, never had to experiment beyond implementation and commissioning. The performance confidence isn't left to chance when it's a commercial endeavour.
A bit like the mechanic's car that's never fixed, the last thing I want to do in my leisure time is do my job....but having a fun job can lead to fun hobbies too in retirement. It will happen eventually.
Great channel.

Yes welcome to my frequency :) I really enjoy my audience. Like minded tinkerers
Found this through KM4ACK's weekly newsletter, glad I did! I bought one of these fishing poles years ago as a support for an ef antenna and I've heard of people coiling their EF wire around them to make a vertical. I like this idea even better. I'm going to get some of the tape and try it as well. Thanks for the idea! I subscribed to the email list, looking forward to seeing where this goes. My hope is to be able to fly with this at some point and not have to rely on stringing a wire somewhere on vacation and for POTA/SOTA operations.
Amazing! Had no idea I had hit his newsletter. Ill need to thank him
Your citing sources, love it, what a presenter. I'm subbed!
Much appreciated!
Look up CCD antenna. Although they use resonate sections of wire capacitor wire capacitor there is alot you can learn. I posted a link but I think it was filtered out. Also at the end add a ring of tape to increase the capacitance.
Noted, thanks!
Very Interesting. I'm sure some people will say you are crazy for trying stuff like this, but try away anyway please. I am very curious about this now. You are contributing very novel ideas to the ham radio community.
Thank you and being labeled crazy is ok with me.
What do I know as a Technician whose never transmitted on any HF rig (though I'm studying for general).....what came to my mind was the conductive tape you are sticking onto the pole secitions----wouldn't it be awesome if it was embedded into the carbon fiber as the section was laid up? I've been around a lot of carbon fiber sea kayaks and they are often coated with a clear gel-coat. The conductive tape possible applied to the sections before clear coating? The clear coat's thickness would of course have to be accounted for in sizing the diameters of the nestling pipe sections. Then there's the thought of a carbon fiber tube that is only 95% complete....the other 5% being a metal strip filling the void and running the length of the tube.
Regardless I think what you are doing is novel and genius. I hope it comes to fruition one way or another because someday I'm going to pass General and then (even though I have acreage and room for an EFHW) I'll want a vertical :) Something else. The SOTA boys (and girls) will love love love your mast that is also antenna!!
Yup I am woking on doing just that! Great minds think alike. Its finding someone to do this for me economically
@@VE6SFX_HamRadioRookie Yeah I woke up thinking about your antenna? Why because I need a super quick rapid deploy vertical 20m or 40m. So scratching the sleep out of my eyes I thought of metallic paint. How thick is that conductive tape you have been applying to the pole(s)?
Aircraft control surface embed metal fabric into the carbon fabric layup to create a conductor to dissipate static electricity from the aircraft. Why wouldn't it work the other way?
This seem like a very good idea for an all band antenna or something like that and it would be very portable
Yes it’s pretty awesome it having to mess with a main element wire. Combine with a magic carpet and it’s nearly wireless
This sounds like a cool, easy to use concept. I was already looking to test some faraday tape as an antenna, but to have a good long range when I visit my families 40 acres (with hill) would be awesome! Thanks for the video, will be subscribing and look forward to more.
Thanks for the sub! More to come that will interest you.
So many possibilities. Wondering if the carbon fibre is necessary for the tape to make the capacitative coupling jump. If not, variant could be nesting plumbing PVC ducting of increasing diameter. (We have a 20m DIY antenna shootout coming up at one of my clubs and I was thinking of not going the traditional wire route but some sort of PVC self-sustaining foil tape approach, but contemplating base loading).
Aside from regular quick-install for this antenna on a fixed basis, also coming to mind is using multiple of these for a phased array, eg. 3 or 5 elements, could even be possible in a SOTA context ...
In the end only one way to find out if it would work. Get some pvc and tape, as well as a LCR meter to get capacitance and this should answer the question. I may try this but it will be a while till I get there. If you do it I would love to hear the results
Add 1 or 2 pieces, 1 inch long beside both ends of each section. It will increase the capacitance and allow for lower operating frequency.
Great to know thanks!
I'm not so sure I'm that! Operate at a lower freq? Why?
@@jeffro. He could get a better match on 80 and 160.
I certainly won't be throwing any crap your way!
I'm an Extra-Class ham, and I love experimenting with "weird" antennas!
I'd be interested in ANY results you get.
In fact, I can't believe I'm saying this, but I haven't been on the air for several years (never thought I'd go that long), but I'm thinking about getting back into it just to try this out.
Thanks for making me aware of this antenna. No joke, this is interesting, after seeing that you had a QSO 700 miles on 60W, on 10m band.
(I know with a "good" antenna, others have gone farther with less power on different bands, not really sure what the record is on 10m band.)
Frankly, I'm not interested in "setting distance records" except as a comparison number.
But I am interested in discovering new properties, etc.
Projection: I'd "predict" that twisting your pole segments (to vary the alignment of the conductive tape) will result in different length antennas, in increments of your pole segments.
I know that you can vary the capacitance between plates by changing the alignment. 😮
Keep up the work, stay in touch!

👍👍👍
I am so excited about this concept too! I have all the parts and will start playing with the idea. My squid pole is fiberglass. Will be interesting to see how that affects it. I'm south of you in WA state. Will watch for more.
Keep me update on your progress with fiberglass. I would love to hear your results.
@VE6SFX_HamRadioRookie will do! It'll be a while. Have back injury and holiday to get past first, so it'll be more than a minute.
This is so cool think you're really doing a great job please keep up the great work and I'll be looking forward to seeing how your product turns out if you put them out on the market for sale I'll definitely be purchasing one
I am working on it and hopefully will have a product in the near future.
That's pretty slick. Especially with it being so inexpensive to throw together. By the way, your amazon link to the poles is linking to the Faraday tape. Little duplication whoopsie there, lol.
Thank you!
Great video I think it's an awesome idea and I would definitely love to have one
Walt Hudson sent me here. Subbed.
Thanks for checking it out and for subscribing!
You’re welcome. You got me thinking … any reason not to try conductive paint? I have a ton of the stuff that I use to shield the control cavities of electric guitars (I use EZ-Slide graphite paint). Heck, I could probably “fold (paint) it over” without affecting the telescoping function. Thoughts on that?
I have tried the conductive paint and yes it works. thing is that stuff is like 100.00 per oz. So it might be out of the range of most peoples wallet. However another has commented about using 'Defroster repair' paint. I am going to look into this for a less expensive solution.
Just some things to keep in mind: You can do a lot of tuning with capacitive coupling, but it just makes the electrical length shorter, not longer. That's why hams use an inductor on the base of their vertical antennas and tune it, because it takes what amounts to a 10 meter, quarter-wave, 15 meter, or 20 meter quarter-wave vertical and makes it electrically longer in order to hit the rest of the HF bands. Also, inductively coupling in one spot to a relatively poor conductor for loss testing is not the same thing as capacitively coupling to the entire length of the material, which is what your conductive tape is doing.
I use capacitive coupling improperly here to be honest. It is both inductive and capacitive. You have some great points though thank you.
As always, Great job experimenting! I'm looking forward to seeing what becomes of this. If you need any testing assistance, please let me know, I have some tape here.
He said you have the best stick! LOL
Ya, build one and let me know what you think. This borders on the magic side of comprehension. I could use some other proof.
@rusted_link he really does ;)
Cool idea, looking forward to seeing what you come up with!!
Me too :)
You are really good at you tube. I enjoy your videos. Keep at it.
Thank you so much!
A neat trick for using a lightweight mast as your whip! Instead of a (somewhat) heavy stainless whip, or perhaps using a longer mast, you might get even better performance than, for example, the CHA MPAS lite.
In all honesty the 17' and 25' stainless whips weigh about the same. But min is much more robust and less likely to permanently deform and or fold over and break. Plus I have a 50' whip I am going to finalize testing on shortly :) That definately does not exist in stainless
I am excited to try this - thank you! Would you be willing to share how you got from the bolt at the end of the mast to an SO-239? I am new to this and would like it to be clean.
Yes I can. You can get them via Ali Express SO239 Base Adapter s.click.aliexpress.com/e/_DCdheBR
How does the cost of faraday tape compare to that of copper tape? It is sold cheaply for gardeners who want to keep out slugs. Slugs apparently hate copper.
They are about the same cost but the faraday tape has sone special properties that make this method work better than copper or al tape. I am slowly figuring out what that are.
Interesting video. Ive watched it a few times.
Thank you!
CCD antennas use capacitors to couple each section together.. maybe a bit of that effect is going on with your idea. Great video!!
I love the comment sections here. I learn so much from them. CCD is new to me and another antenna to research. Thank you!
love this but I don’t have the means to create the connector in the bottom, would be very interested in the commercial product. KB2GCG Jerry
Love to hear this!
This can be a revolutionary HOA antenna. Like many others, my house has a wood facia board running along the end of the roof. I had planned to use some eyelets and create a random wire antenna that would be reasonably well hidden. But this might even be better. Hiding the drop from the board to the window might pose a little problem. I wonder if I could extend the tape onto the stucco wall. Would it stick? Would painting over the tape affect it?
Absolutely you could extent it. I am not sure it would stick to a stucco wall but given how inexpensive the tape is, get some and try. If it does not work you can use it for many more things. Seriously I have rolls of this in my bug out bag for improvisation.
What about painting the rim lip of each section with defroster repair paint for rear car glass to make better connection???
Definitely something to look into. I do have some conductive paints but they are prohibitively expensive. This stuff I had no idea existed and will look into it
Thanks!
I like the idea of this antenna. this might be yet another way of providing people with an antenna for those with limited space as well. I don't know about restricted covenance, though.
I agree and there is some more tricks up my sleeve for them as well :)
Very interesting information, what is that you are screwing the antenna into?
It is a so239 connector I got on Ali Express s.click.aliexpress.com/e/_DmBHoTF
Great work brother, keep it up.
Thanks!
Carbon fiber IS electrically conductive. I sanded the finish off a telescopic, attached a wire with a hose clamp, and made DX contacts. Use the carbon fiber pole AS the radiator.
Yes but it does not effect antenna radiation in any significant way
@VE6SFX_HamRadioRookie I'm saying omit the conductive tape. It's not needed.
It very much is. This does not work without it
@@VE6SFX_HamRadioRookie Japanese hams and myself have direct fed carbon fiber masts with good results.
Ok then this will need to be tested. With and without the tape. Thanks for the suggestion
How much power do you think this tape could handle? Think it could handle 100 watts SSB regularly? How about 100 watts FT8?
Ive been running 100w SSB for the last couple months no issue. Ran 50w Ft8 the other day with no issues
@@VE6SFX_HamRadioRookie this may be my next Pota experiment. Maybe paired with a 9:1 👀. Could be way easier than setting up a wire! Haha
@@TrekOnTheAir FWIW I have been using one naked with a antenna tuner and it works just fine. Soon Ill do a video on the SWR sweep. Here is a teaser 30% is below 3:1 between 3-60Mhz and 60% is below 5:1 on the rest. Its kinda crazy really. I have been doing Italy, Wales and South America from Calgary on SSB between 10-40m regularly. 6-10 thousand Km. On FT8 and WSPR I have 15 thousand Km
Have some spare tape and find out! Digital modes can be "hard" on antennas "power ratings". I determine my power ratings. I bought an "online", cheap vertical rated for 200W SSB and digital. After using it for several months for digital contacts (max 75W), I noticed the balun melted through the housing box. Found my weak point. I build a new box to hold a 2000W balun. The box included new wiring, connector, and screened vents. I used that antenna for years with SSB contacts using up to about 1200 watts. My point is "find out". Protect your radio(s), but give it a try. When it reaches the limit, fix the weak point. Love this hobby!! -73 de KN1B
This is going to be a really fun journey. I'm very interested in the near zero footprint of this setup. Time to hook a g90 into it and hit send.

@@jeffro. Type of hf radio with a built in tuner. Xeigu brand
Your antenna is similar in principle to an antenna published 20 years ago or more by the ARRl in the antenna compendium. The published ARRL antenna was a dipole interrupted in the arms by a series of capacitors. You could check their article and get hints for your experimentations.
I will have to look it up. thank you for the tip!
Hey buddy, cool to see that you're into Ham Radio! We'll def have to try to hook-up on the air. I run a FTdx10 right now and picking up a FT-101 station this morning because everyone "needs" a boat anchor. Hope you're well!!
LOL the boat anchor will not make you go bankrupt like a boat.... What is your callsign? I'll be on the lookout for you. Wishing you are well too!
@@VE6SFX_HamRadioRookie KC3UDZ right now, I will probably get a vanity when I pass my Extra.
I have used the fiberglass version of these poles for several years with my RV HF radio. Have you tried feeding this antenna with a 9:1 balun. It works well for with a 33 ‘ wire strung inside a fiberglass squid pole. I like your idea, Eliminating having to string a wire inside the pole when setting up the antenna would be a time saver. the I’m going to order up some conductive tape and try it on the fiberglass pole I have. If it works as well as the wire does, I’ll let you know.
One problem I have had to contend with is sections of the pole collapsing due to wind vibration. Plastic hose clamps, appropriately sized for the different sections work well, but it adds a bit to the set up time. I only use these if I’m setting up for a long duration, or wind is going to be a factor.
yes collapse is a issue and I have had luck with zip ties at joints
Very impressive creative approach! Kudos!
Thank you very much!
Cheers from a fellow ve6. I am va6gg in Edmonton. This is a really cool concept. Ignore the old farts saying it's all been done before. Maybe the idea was floated before but we didn't have cheap and easy access to things like light weight large telescoping poles and conductive tape at current prices. We couldn't get it all delivered in a few days to our door with a couple clicks. It's still a really great idea and quite practical now given how easy and cheap materials are compared to let's say, 35 years ago. If an antenna performs at least as good as a mono-band dipole, then you are laughing. I remember when a roll of conductive adhesive copper tape was 60 or 70 bucks. Now it's 10 for 3 times more. This conductive cloth tape is something that simply wasn't available to the consumer in the past. Keep the project rolling. I want to see what you come up with on this antenna. Multi-banding is definitely a direction you should explore. I think conceptually it should be fairly straight forward to accomplish, though you'd have to switch perhaps to a more resonant radiator design and find some way to key each section to fit together to achieve the correct radiator length for each band. Imagine if you could create this antenna but resonant so no tuner required. That right there would be about the coolest new antenna design since the DX commander.
I think vertical antennas for HF amateur radio got a bad wrap for a long time and some smart creative people have brought them back into favor. They work amazingly well and don't require big, heavy, complicated and expensive antenna support structures along with the real estate to erect said antenna support structures.
Thank you for the encouragement! And agreed the world has changed. Hopefully the creative mindsets can bubble up again and not be suppressed buy the grumps

That was not staged. I was exhausted
@@VE6SFX_HamRadioRookie i know ! but it was also funny and entertaining like all of your videos ! 73 from germany

The tape could be used to make a slot antenna, which would be fun.
Look back about 3 videos ruclips.net/video/t2UsV3Os9xk/видео.htmlsi=-O-mI6ZeoqrHmCkm :)
Was that 0.1dB loss for the few inches he was testing versus the 10x feet you are using?
Yes it was but you can go into his video and he will explain it much better than I ever could. In the end the losses are still inconsequential. Thus this antenna working so well
Hi Rook! Very innovative concept...I'm building one (or two) now. I'll try copper tape instead of Faraday tape. Have the copper tape but do have yards of Faraday cloth which I'm testing for ground planes. The copper tape will have better conductivity although my tests on Faraday cloth show it's surprisingly good on that score. The practical impact of having a telescoping fiber pole that requires no wire is a move toward Occam's Razor in portable HF ops, IMHO. Looking forward to how you play this out. There's a Latin phrase for don't let the bastards get you down but I don't have time to look it up right now. You might suggest that viewers who get triggered by innovation "that shouldn't work" go watch some cat videos. The Smoking Ape can hook you up on some references, lol. 73 de K4FMH
I thought you were going to put the tape inside the pole, top to bottom so it hung loose inside which I figured was genius. But when you you put it on the outside I was even more impresseed. Is there nothing you can't invent with that tape :)
I just bought a large amount of the material to use as a magic carpet but now I'm wondering is I can put an adhesive backing on it and laser cut some kind of coil / trap which could stick to the pole and is very repeatable and low profile.
You are an inspiration to a 59yr old antenna engineer.
Thank you! Trying to get it inside was too much of a pain. Making coils with this is on the list of experimentation to come up.
@@VE6SFX_HamRadioRookie My tape arrived yesterday, I have a 10m pole kicking around, let see what it can do. Again thanks for the great idea.
@@RobCanada Awesome let me know how it goes!
Maybe put a loop of the tape around the circumference of the pole at the end of each segment so you don't need to line up all the tape strips?
Solid idea and will try in the future
Interesting idea! Did you use a balun? I wonder if it would be possible to leave a 'tag' of the tape at the bottom end and connect that to a 4:1 or 9:1balun as would be used in a randon wire antenna?
No balun. And yes leaving a tag and alligator clip will work. I find the antenna performs quite well with no balun and the SWR is manageable by the atu-100
Very good idea Thankfully 👍

@@VE6SFX_HamRadioRookie Many thanks for reply
This is freaking WILD!
If the antenna works collapsed, have you messed around with what can be done with it collapsed? Maybe collapse every other section (use zip ties) to keep the capacitive coupling from hopping around? I'm thinking about getting a 30 foot +/- (like 10 meters) tall antenna that works the 40 meter band. Does the tape work like an inverted V if you go up one side of the mast, across the top, then down the opposite side? I'm thinking maybe an 80 meter band antenna that's 30' +/- tall.
Maybe run multiple strips of tape up the mast like a Faraday Cloth DX Commander? With a cloth groundplane? That all collapses and folds up?
Sorry if I'm making you drink from a fire hose with all my questions. Too much beer turns me into an excited 6 year old with an engineering background. 😉
Totally understand the fire hose of ideas… appreciate your enthusiasm. Few things I’ve tried. And FWIW I can tune 40 and get this 80 with the 33’. There is magic in the faraday tape I cannot explain… yet.
I really liked your questions. I found his video to be excellent and your follow questions intriguing.
Ok, this seems to me an exercise in learning, I mean, we all have to start somewhere I guess. If the goal is to set up a capacitive radiating dummy load, you're on track. But if your goal is to get on the air, just use a length of ware, a 9:1 unun, a tuner and get on the air.
Did you watch the video? Did you see the contacts I made with it? This is far from a dummy load.
FYI carbon on its own is a poor radiator but with the conductive tape it becomes a radiator. the ohmic resistance of just carbon is crap and for the most part is a dummy load. But when you add the tape it changes EVERYTHING.
ruclips.net/user/shortstFA2LB3aKKQ?feature=share seems you might need to go back and have another look at fundamentals of antennas... Just sayin
How very exciting sir and was riveted to your video and experiment. I will be in anxious follower I'm kind of a Frankenstein antenna guy myself even though I'm just getting into the hobby. Most interesting for me was the coupling and adjustments that are possible by rotating or turning sections. And I wonder and plan to see if it is possible to achieve the same along the lines of a large telescoping whip antenna element as well.

OMG, this is the coolest friggin' thing! Thanks for sharing. I must try this. Regarding carbon fibre, it's unfortunate that the ham world is filled with finger-wagging naysayers, but in my experience, these are all 'armchair hams' (a term which in their case is a tautology) whose only attempts at experimentation are in making stupid comments to YT videos, thus contributing not one whit to the hobby.

Very interesting concept, well explained, Thanks a lot.
About these Aliexpress poles, I've bought one one these supposedly 13m long poles and it's hardly 10m long. Sams for you?
Not sure it was from the same seller, but it does look familiar.
The sellers even with different brand names are effectively the same seller. And yes they tend to over promise. FwIW my 13 m pole is really 12
@@VE6SFX_HamRadioRookie I admittedly might have not counted the super-thin, unusable for anything last segment to measure 10.something meters long only. Yes, I did suspect too that all these offers were actually coming from the same seller.
For long poles (10m up) the only alternatives are the much more expensive Spiderbeam and such poles, that are too thick at their base to fit into any ground anchor I could find and too heavy for me to bring them up on my own when extended and there's any wind blowing.
I have a 12m one and I hardly ever use it, I work with these cheap fishing poles instead.
EDIT for an extra question: do you think these really are made of carbon fiber and not just plain fiberglass? I have doubts.
Yes to all of this but since it is just tape to the outside of the pole suddenly these weak segments become usable :) No extra loading just some tape
"Yes", like you do think they're really made of carbon fiber? Well, OK, I really thought otherwise. I broke one at half its base segment on a windy day, they're kind of fragile.
I get the idea of "no extra loading", but how to you apply that tape to a segment that's barely of 1 mm diameter? I'm curious
Cut the tape down thinner to 3mm width and it fits fine.
Very cool. Looking forward to more of this.
Me too! My head is exploding with ideas!
I always thought that carbon fibre poles should not be used because they are more lickly to attract lightening.
Well sure but would a wire or metal tubing not be worse?
You could put tape on the opposite side of the tube and experiment with linear loading. Lots of paths to go down. VA7VEB
I can but to be honest the idea of getting this tape to the inside of the poles is daunting to say the least
A very interesting concept but, as you say in the video, I would like to see a lot more work done on measurement off capacitance at the joints, loss and or gain, effect of flex in the antenna, and a whole bunch of modeling and experimentation. It could prove to be a fantastic design but it also could prove to be a money spinner for cheap Chinese manufacture producing low quality knockoffs.
Why not cover the entire surface of the pole with tape?
In this case it makes the outer diameter too big and then the sections do not extend they just are able to nest. Hope that makes sense.

If you mean just extend the carbon poles alone. They are quite resistive and do not work. They are effectively a dummy load. ruclips.net/user/shortstFA2LB3aKKQ . If you meant a stainless steel whip then I do not know of a 33' stainless extending whip existing anywhere or if it did it would be no where near as strong in a wind load
@VE6SFX_HamRadioRookie no the steel antennas that are on every radio.
@VE6SFX_HamRadioRookie they make aluminum telescopic to that lenght.
Yes there are aluminium masts that tall but they weigh a bit more than 1.5lbs I currently have a 50' up and testing it as well. I am gusessing that the weight is substantially more than the 4lb I have if it were made of aluminium.
Dude.
Dude!
oh we're calling it Faraday Tape now eh? OK.
What was it called before?
I never heard of this tape, what is it actually called?
@@VE6SFX_HamRadioRookielooks like it’s called conductive fabric tape
It is also known as Faraday tape if you google it or search on amazon or ali express etc. This will bring the tape up in results. It is made from faraday cloth so it goes to say faraday tape is a reasonable assumption/
Great video, Ben! I should warn you though that you're dangerously fond of objective reality. All this insistence that the data your instruments and experience indicate beats the blind babble of conventional wisdom... that'll get you in trouble, OM. Ask me how I know.
Anyway, awesome channel! I'll be back.
Oh I get blow back for sure. But I just use the hot air from the blow hards to fill my sail to go do other cool stuff :)
Great idea! K7OSS
Thanks! 👍

Right back at ya!
The smaller the antenna, the smaller the antenna aperture. Size matters. "Just because it resonates doesn't mean it radiates."
So the contacts I have made SSB 6000+Km away and FT8 over 14000Km on it must definitively prove it only radiates?
Receive aperture, yes. For TX, if you put 100W into a matched antenna, with a lossless matching circuit, and there is no part of the antenna that is getting hot, then 100W has to come out as RF. As the antenna gets smaller, it approaches the radiation patern of an isotropic antenna. Which is only a couple of dB down from a dipole. The difficulty with a small antenna relative to wavelengh is in actually achieving a lossless matching circuit and antenna with no lossy parts.
@@SimonBlandford Oh! that helps me figure some things out. Thank you.
Your lips don't quite move with the sound of your voice. Do you know Karate?
LMFAO, well played. I will try and fix that in my future edits :)
Ran Dumb.
Not sure if this is a funny. Or you are trolling me.
Intriguing, clever antenna idea. Aloha de Russ (KH6JRM).
Aloha! Thank you
Awesome idea! I'm definitely interested in how this turns out.
Keep thinking outside the box, please!!

Wait, there is a box?
@VE6SFX_HamRadioRookie Exactly!!!
@@VE6SFX_HamRadioRookie Exactly!!
I would use mine for SOTA activations if there was a way to keep the weight down for a guying solution.
Easy peasy… ditch the paracord and get some heavy duty spectra line. You can get stuff with higher breaking strength than paracord. It’s in the fishing section of most sports stores. Anyhow it’s a fraction of the weight of other solutions
@@VE6SFX_HamRadioRookie Right you are. It's incredibly strong. I've used it as well as dyneema for my parafoil stunt kites. I think dyneema has to be sleeved to help it maintain strength for my application, but I sleeve my Spectra line anyway. Spectra line, when purchased for deep sea fishing and not kite flying, is cheaper and works great. I've used the methods for retaining 80% of the strength in a knot for years. Pull as hard as you want and when you're done, the tether pops apart as if you never pulled on it in the first place. Speaking of kites, I want to try a big delta kite to pull up a wire and use that as an antenna. It's stout enough to hoist up a simplex repeater. Thanks for this video! I like these affordable performer videos. :)
Are you related to Marconi? Awesome innovation! Keep it coming and thanks for sharing your projects with us. Matt / M0DQW
I am humbled by this comment. Thank you and I would never think of myself as that smart. But I will take the compliment. Again Thank you
