As part of my amature radio fun and games I had to add an antenna.
Wanting to do a little bit of everything, I bought a discone. It’s not great gain, but it covers a broad range of frequencies.
Because the HOA is pretty strict about such things, its a lot lower than I would like, but so far, after a month, no letters to take it down….

I just need a way to both transmit and receive through it.

I have also been more active in using SDR, software radios. It’s a pretty steep learning curve, but it allows all sorts of signals to be picked up.
We have watched pager messages, weather satellites, aircraft, other hams and weather stations. Not bad from a 20 buck USB radio and some free software.
