packetflux is the only way to sync, everything else is garbage, GPS
pucks aren't reliable, CTMs and CMMs are a waste of money and are no
where near as versatile, cambium cant get their pucks to work, so I
wouldn't trust their little syncpipe knockoffs either. Ala-cart sync,
switch agnostic, no worries. Small sites you can split one injector to
power and/or sync a mix of voltages and pinouts, PLUS (this is a big
thing) two Fridays ago, after hours, had an issue with getting one
working, got direct communication from packetflux and got things
going, good luck with that from cambium and their new tiered support

It's not only the antenna. Newer 1000 boards and all 2k's have a
GPS+GLONASS receiver. They also updated the 450AP a couple years
ago with a revision that includes this receiver. GPS-only kinda
always sucked. With GLONASS added, you have a lot more sats
available, so the probability of maintaining lock is much, much
better. I really wish Forrest would start using this in his pipes
and boxes.
Typically moving the antenna a few inches or a foot says there's
some multipath going on. And sometimes the receivers just get
confused and need a power-cycle. I have some SyncPipes on 1-foot
stand-offs with another 300' of tower above them and rain will
make them see no sats.
What has worked better for me than anything else is a SyncInjector
and pipe/box on the ground away from tower steel and lots of RF.
Even then, those get confused sometimes too. Usually when I see
really bad fading at night during the summer, I'll see that
tracked sats will go from the normal 9-12 down to 5-7, but they
rarely lose lock.
Once upon a time, I had a SyncInjector and a pipe running in the
server room for 4-5 days (because I forgot to run a cable outside
for the pipe). It worked fine... until it rained.

When we first started using EPMP, (5ghz, with GPS) we had some
AP's would keep losing satellites. Then after our first
couple installs, everything just Worked after that. Slap the
GPS antenna on any random surface, and lots-o-satellites with
no issues. Now the New AP's we're getting out of Distribution
have the GLONASS label on the antennas, and we're back to
having hit and miss GPS again at new sites. Are the new
antennas less sensitive? At one location, 1 out of the 4 APs
was going from 12 satellites tracked (20 visible) to 0
Satellites tracked (still 20 visible) at random times. We
moved the GPS Puck about 4 inches vertically, and now it has a
steady 17 satellites tracked.
Has something changed with the Antennas?
