I live in an area that has HOA rules against outdoor sw antennas. I think my best bet is a stealth loop antenna laid directly on the roof. It would be trapezoidal in shape and about 100 feet long. I want to feed the receiver with small coax {RG 174}. I want to make a balun on a ferrite rod or air core type. I have some torrid cores but go crazy trying to wind them. Any ideas on the ratio I need {4:!, 9:1, etc} and a place to get plans for winding.This will be a? receive only antenna.
