I believe Chuck said GPS does nothing in FDD mode. It's really only for
TDD synchronization. Obviously with FDD you're always transmitting and
receiving simultaneously.
I would run the co-located radios as masters on the same Tx freq. That's
really the only way it's going to work anyway. 15 degrees may not be
enough separation in azimuth. Maybe turning the power down on the
shorter link would do it.

Are you doing half or full duplex?

Absolutely. It will not work without it.

Out of curiosity…should I be turning on GPS timing? Does it even

Make both airfibers on the shared rooftop masters, with reversed
tx/rx. I think the most we have at one location is 4, and there
is no more than 10 feet from end to end of the structure. They
are on slightly different azimuths.

We have 2 Airfiber 24’s co-located on a building rooftop… they
have about 15ft horizontal separation. The one air fibre pair
is aimed at a tower about 1KM away and not the tower side we are
about 75ft in the air. The other Airfiber is located on a
building across the road at the same height. The azimuth is
about 15 degrees off of each other. The link from roof to
tower, works 100%. The link from building to building is about
400ft away and we are having weird issues getting it to link.
Is there some sort of co-location magic to make this work? I
read somewhere that we should have master or slave mode matching
at the co-located sites.
Any words of wisdom are appreciated.
