We had to move our antenna slightly higher because of serious interference issues caused by the tower. We were told by an engineer that we were ok in doing so because of FCC allowances for variation and because we were actually lower than where we should be. Do you know what the exact FCC allowances are for height variation. Is there an easy method for securing an exact height as to our antenna height?
I read somewhere also that the FCC allows for a 5% power variation up and 10% down. I think there was one time where our power was below the threshold ( I think it happened last winter) and also another time we were slightly above 5%. Usually we're in range but it concerns me that there have been a couple of times that we were off by more than the FCC allowance. We're an lpfm .. I wonder if it could be because lpfm transmitters are just not as good as the big company stuff. Could weather affect it? thanks jj
