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

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
I am having some 11 GHz links coordinated and the draft PCNs they sent me
have one site high on one link and low on the other link. They are however
different sub bands, and one is HPOL and the other is VPOL. Does this make
it OK? I could probably do one of the links in 18 GHz.
