Re: re: QRM 2m, question for sat builders



The path loss goes up with frequency but antenna gain goes up at the same
rate for a constant size antenna. The pointing accuracy must be greater at
higher frequencies but for the size antennas that amateurs use, this isn't a
limiting factor below 2 GHz.
