I had a situation like this with a Dragonwave backhaul a few years ago.
Every time the OAT dropped below ~~ 25° it would drop offline. I found I
could get it to "live" by wrapping the ODU in foam insulation. Helped me
isolate the problem, and was able to schedule an ODU replacement.

I have a 3.65ghz 450 AP that was running flawless for over 6 months
until we got our first really cold spell last week, temps dropped to
near 0 degrees a couple nights back to back and when I woke up one
morning the AP was dropping offline. Logged into the Mikrotik 2011 and
it showed Ethernet was flapping. (was originally going through a Sync
Injector). I had an old FSK AP going through the same sync injector
and wasn't showing any problems. I tried switching the ports on the
sync injector, changed ports on RB2011, eliminated sync injector and
used a standard Canopy SM power supply. Finally I even switched the
known good Ethernet cable from the FSK AP to the 450 and the port is
still flapping. Won't lock to 10-baseT either. I am thinking at this
point that I am going to have to replace the AP.
