Love it!!!!! AE4YW

Hi Rudy, Very Interesting design. What is the Bandwidth like, is it High Q or does it cover the 20Meter band pretty well? I'm wondering if it would be a good attic antenna.

This is one of many things about Mateus radio…guys like you that never rest and continue to innovate. Thanks!

Thanks 73

Thanks for sharing your knowledge. KF0MOE

Cordial greetings colleague Ruddi, I have been pleasantly surprised with this antenna project, could I publish a construction scheme of it, I think that there are many of us who are interested in a multiband antenna for small spaces. 73's Dx's

Does HOA mean your a homosexual? 🤔

I tried Tena ladies but didn't receive shit 🤷🙄

I am a new Ham, do you have to use the LDG RT-100 remote antenna tuner? Or will any tuner work. What should I look for?

SIMPLY GENIUS!

What would you think about using an air wound coil approximately 6 in diameter made from 1/8 in copper tubing (self supporting), with mechanism to expand or contract the coil, thereby changing its inductance enough to not only tune across the band, but also change from band to band ?

Can you demonstrate using it on a radio?

Looks like a nice homebrew antenna for portable operations.

Got a link for the whip? I have not found one that is not 10mm thread instead of the 3/8 24 that I already have many things for. Even a good source of 3/8 24 to 10mm adaptors would be great! Thanks for open sourcing this!

Nice home brew, well done.

_”(scale the lengths for other HF bands)”_ Now if I can just find a *400 inch* long, *24 inch* diameter pool noodle for 80 meters … 😀 Or maybe a _”Slinkie™ dipole”_ *73 de AF6AS*

I like it, but I think the Mad Dog coil is a better design, more compact and lighter. I would imagine this would cost about the same to make as it would cost to buy a commercial version, such as the Mad Dog, Wolf River, Ten Tec or one of the many Chinese made coils that do the same thing once you assemble and obtain all the parts, I doubt this would be that cheap as an antenna, at least here in Australia. I do like the idea of the full kit inside though and the antenna stowage up the guts of the mount, Very clever design.

Hello...I like your design. I have looked inside several 32 foot vertical HF whip antennas in my time. I was a radio guy in the Navy for the better part of 31 years. So I had the privilege of seeing "deconstructed" vertical whips. The twisted strap approach you opted for is okay but not the way that I have seen commercial grade whips made. It should work though. You also need to drill a small hole in the cap end of that PVC pipe to drain off moisture buildup. Moisture will build up in it. Assuming that the cap is pointed down towards the ground right?

Hi Rudi a very informative presentation. Is it possible to use mix 43 for both a CMC and TLT as I cannot get a mix 31. Thank again for the presentation. Joe.

That’s really cool that it’s all encapsulated like that.

Nice work Rudi! deKK7BUC

What a unique looking antenna (to start with)... but this looks like it would be fun to build and easy to deploy. I'll have to try it (after I learn how to build CMC's and UnUns)!

Fine business Sir. Innovative. You've succeeded in ariusing my curiosity, now off to build it

Looks interesting indeed! Do you plan a follow up video to show us how you set it up? I'd also like to see how well it performs.

Remoteley tunable Idea: if you could get a short steel rod with a motor drive near the base you could drive it up and down inside a region of tighter (closer-wound) coil turns to alter the inductance and give it some remote fine-tuning across a band. The motor would turn a threaded rod and and work a bit like a screwdriver antenna. The key thing is to move the steel bolt into and out of a section of tighter coils - in even-spaced coils there will be only marginal change is resonance. Not sure if there are better materials to use(steel is lossy and kills Q) but a steel bolt is cheap and easy to find for an experiment

Intriguing design. Thanks for sharing!

That's awesome! I like how you hid everything inside and used a coil counterpoint. EXCELLENT JOB, SIR!

Thank you for sharing this with us.KC1TWE.

Very nice! Would an antenna like this work better or worse if it were elevated, instead of on the ground?

I have never thought of doing a coil for the counterpoise(?) ground plane(?) that is epic! How long of a piece of copper did you use? Or is this more a area thing vs length?

That's amazing, Rudi!!! Can't wait to see the finished product. 73 from W5ODP 😎

This was an excellent presentation to attend. Thank you for presenting at HamCon Zion. Now I need to get started on all of these hands-on examples!

This was an excellent presentation to attend. Thank you for presenting at HamCon Zion.

How does it work? What do we sacrifice to get the length so small?

Great video and very cool design. As a new ham just over a year ago I've been exploring different antennas to build. Definitely on a budget so it's cheaper than buying new, tho I love building and then having the joy of using it makes it so much better. Thanks for the video, looking forward to more. 73's

That's a cool idea. Thank you very much for the video. Out of curiosity, what wire gauge did you use? 73.

I am new into ham radio and would like to understand this "stay stealthy", "conceal" "nosy neighbour" things a bit better. Is it really likely that the radio equipment will cause issues in neighbours devices even when used wihtin legal limits, or is this more an "esoteric" thing (like neighbours flatter themselves that the antennas have impact on their well-being)? 🤔 By the way - I am surprised that you Americans worry so much about these things. It thought this was more like a "German" thing (I am German ...). 😉

What gauge wire? How much power will it handle?

Its nice ti see that there are still hams out there that build their own antenna's rather than just buy some piece of junk. The Problem with most new hams is they have not had the privilege of an Elmer to teach them along the way. So they just buy what they need instead of experimenting and gaining knowledge and having the fun of seeing the fruits of their labors on the air. I have had that thrill for over 50 yrs and still get excited to build something and watch it work and see my creation create qso's good show. RudI!

Any chance of measured plans on PDF?

Great idea. How well does it preform

very cool! Genius my friend. Thank you!

Good content but pity inpicture video usually too small to see. Otherwise interesting tuition

Man, I think I found my next project!

Fantastic!

Thanks for sharing, great idea . I hope the next video is showing this ant on the air. 73 zl3xdj

This is brilliant. I live in a condo and im getting my licence. Figuring out an antenna was giving me a real problem.

Again another good show. THX, 73, David.

Dumb question. Why do they make the open wire line exposed in the first place if it doesn't work well when wet?

Hello Rudy, would there be any advantages of doing the pool noodle on a schedule 20 say 6in diameter pipe instead of the smaller diameter pool noodles? Im thinking larger diameter might allow for a little larger antenna and maybe better performance? What are your thoughts? Over the winter its hard to locate pool noodles in my local stores. kk7aim
