Any idea how to slove intermod problems at repeater location, very close (
150 meters) to VHF repeater antenna is located FM-TV tower with 7 strong FM
channels, nominal power is from 5-10KW + antenna system gain. Bad thing is
that combination of 104.7 MHz + 145.7 MHz (repeater tx) - 105.3 MHz = 145.1
MHz ( same frequency for repeater input ) !



There is 3 +3 cavity duplexer pass/reject type and professional type of
vertical dipole with 0 dB, I`m sure if notch cavity can change this problem
or installing high quality FM Trap filter to existing setup.



Tnx for any help !
