Well, it's nothing interesting, just a balun for an antenna.

At first, I thought I would make an EFRW antenna, then a dipole, because it's effective, but in the end I ended up at the EFRW idea, for simplicity's sake.
Because, yes it is dificult to find a place between tres that's exactly 75m wide.

The main purpose behind it was to make a simple field antenna that can be easily unpacked/packed, mounted, and carried.

This balun wasn't soldered so nicely the first time, but I had to fix it because a guy wanted to help me and soldered it, or rather, I should say "glued it with a hot glue gun,"
in such a way that more radiation would be emitted from the wires to the balun than from the radiators leading from the balun.
It was a sad horror of lack of knowledge, but luckily it's beautiful now, I even got a spool from 3D filament so now it's quite nice and easy to unpack/pack.
