SNRs probably suck though. 8 degrees is probably about 10-12dB off of
the main beam. Ungood for 64QAM. But hey, if it works, it works. I just
wouldn't expect it to work all that well.

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.

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.
