Picture of the WIP, but ready to test prototype #dipole #antenna. Despite what the camera perspective suggests, it's approximately 38" overall length without being extended.
The end goal is that it will work for 20m - 6m, mounted on a fiberglass mast.

This is peak antenna design and you won’t convince me otherwise.

I realize they're not magic and that crap antennas are still crap antennas, but what are the internal mechanisms that allow antenna tuners to do their thing? How do modern digital models sense #SWR and know what decisions to make to improve the match? Also, makes them cost as much as they do? I've noticed many antenna tuners are quite expensive. Explain it to me like I'm five. Links welcome.
Working on a dual purpose antenna tripod 😜😎 #hamradio #antenna #diy #McGuivering base or coil loaded vertical with a top to mount my QRP guys vertical when I'm feeling lazy. May do a tap on the coil haven't decided yet. Having a #3eprinter makes life fun. Always building always #making making

Bit of a shame its an Android (phone) app, but if you are interested in DIY #antenna building, this looks pretty interesting.

Thank you to everyone here that has helped so much for the #hf #antenna work. It will be presented at #qsotoday academy in September.
This is a shortened antenna that uses a meandered or linear load instead of coils or capacitors. It's a design with a long history but is not as well known as it should be.
@M0YNG I mention you and this server in the presentation, and recommend hams to come here.
It's a real privilege to have such a positive and supportive community.
Acquired an extension pole with a standard broom thread on the end. Thinking it would be neat to try out putting a 3D printed #hamradio #antenna adapter up there -- dipole center? Any existing #3dprinting models?

Nothing cant stop me to interface this with that...😂

Hey lovely folk of #amateurradio, I am planing to make a field portable #yagi/ #moxon for maybe up to 20 meter. I am considering several design choices and came by with the idea of vertical moxons hung from fishing poles. I wonder how this would compare to horizontal and higher hung #antenna. Interwebs gave me no answer. I aim to make it simple and compact and vertical idea is good for that goal but I want this to be my efficient antenna so... Any ideas?

Also I tried a similar thing with UV82-HP and the same cable interface connected to a Raspberry Pi with various packet software, performance was terrible compared with higher priced radios. They are what they are, cheap fun.
