I know most uses duplexers and one antenna. In commercial work in Fla.
I've done we use two antennas. Receiver on top and 50' pluss on the
bottom for TX. Gves about 60 - 80 DB isolation. I figure that at 1200
Mcs that 50 would be over 100 DB isolation. Whwn at 146 Mcs it would be
bout 60 Db.
HMMmm....
By using Duplexers as well as two antennas, would that be better?
or even dropping the duplexers all together and use notch filters to
knockout the wnwanted signals.
