How good is your antenna for the station that you are trying to

Do you have an outside antenna?


A 1/4 wave ground plane in the attic of a wood-framed house. Some of the
local stations (within 5 miles) are very strong, and I can get some
stations
80 miles away (not with good audio). The antenna is not the problem.


Don't be so sure. It used to be (and probably still is) that commercial
FM transmitters were almost always horizontally polarized. A pair of
crossed folded dipoles (made from 300 ohm twinlead) in your attic will
probably have markedly superior performance to your vertical quarter-wave.


Thanks, I'll try that.

I thought they were going to vertical polarization because of car radios.
I'm wondering where I read that, and whether it's true.
