The radios certainly don’t have any isolation from this type of interference,
so what you’re relying on is totally on the antennas - there’s not much FSL on
these and I wouldn’t bet my life on a 2’ Category B to provide the kind of
close-coupling loss
For FDD systems that require a minimum frequency separation between
Transmitters and receivers, one should always follow a standard high/low
frequency plan. In fact for efficient use of the band for all parties, the
high/low plan should be followed religiously. Violating the established
high/

The radios certainly don’t have any isolation from this type of interference,
so what you’re relying on is totally on the antennas - there’s not much FSL on
these and I wouldn’t bet my life on a 2’ Category B to provide the kind of
close-coupling loss needed on a co-located system. AT&T and MCI
To my knowledge the radios and dishes have enough isolation that H/L match
at a site is not necessary unless you're almost pointing in the
same direction with those dishes (or have a TX frequency at one site
overlapping a RX) . The opposite polarity increases the isolation so you
have even less wor
