I am currently getting my EE degree, and I'm trying to build my first antenna for a weather balloon.
I understand with a dipole, you want the feed line perpendicular to the antenna for at least l/4, but what about loop or quad antennas? It seems like people like to route the wire to the boom, then go perpendicular, then go parallel down the mast, which doesn't make sense to me.
What is the best direction to feed a loop, or more specifically a quad antenna?
