[QUOTE="Terryl, post: 1136987, member: 369937"] The problems I have run into in the past, is that some of the cheap 2 way signal splitters are not too well balanced for combining two antennas, one side may have less/more signal loss then the other, this can cause phase problems with the two signals, is one antenna input is slightly out of phase with the other it will degrade the signal, by how much is anyone's guess. We used adjustable couplers for joining two or more antennas, watching the signal on a spectrum analyzer we adjusted things till all was matched up. [/QUOTE]
