If there is anything nearby outside it sometimes it helps, but when antennas are right next to each other, Interference outside the duplexer band can stil...

I know how they are u...

I'm just wondering, has anyone ever put a low-pass filter (Say a Telewave, Celwave or Decibel Products ~200w) tunable unit between the duplexer and antenna? I know a low pass are used after a circulator to reduce harmonics on the transmitter port, and some repeaters even use high-pass filters placed...
