I'm working on an educational app for #amateurradio. In it I have visualizations for different factors that affect radio signal propogation.
My AI agents hit a quality plateau. Prompt tweaks weren't helping.
The problem? My agent was anchored to MY understanding of the domain, reflecting my blind spots back at me. 🤦♂️
Here's how I got through it:

The Ultimate Guide to Affordable NVIS Comms (How to Build a Regional Off-Grid Radio Box)
https://www.youtube.com/watch?v=ZZxR-qtGH7c
I build a $200 portable HF radio box and test whether it can really communicate 100+ miles off-grid using a technique called NVIS. This video walks from first principles to real field tests, showing how normal people can stay connected when infrastructure fails...

Was ich hier in Patagonien schon häufiger gesehen habe:
NVIS Kurzwellen -Antennen bei Hilfsorganisationen. Krankenhaus, Feuerwehr usw. Anders kann man hier wohl die Verbindung über die Berge nicht halten, ohne alles mühselig mit VHF-Repeatern voll stellen zu müssen.Alles niedrig hängende Breitband-Dipole nach dem T2FD Prinzip.

I can't find for sale anywhere a 1:4 #balun for HF. It is for a low height 40m inverted V #NVIS #antenna. Military versions such as #AS-2259 use the custom coax support pole as an impedance transformer.
To be clear, I mean 12.5 ohm balanced antenna side to 50 ohm unbalanced coax side. The ones for sale on eBay/Amazon seem to be mislabeled 4:1 ones.
Making one isn't an option: my hands don't work properly.
Anyone any ideas.

@Dianora
Yes, #NVIS or Near Vertical Incidence Skywave is the #AmateurRadio mode that interests me for its practicality for reliable regional communicates independent of any infrastructure. -
