I found an old graph from one of our tickets with Cambium.  For the archives...

Very interesting.  When you say pucks up, you mean laying flat so they point to space?

    I agree, but we graph the tracked/visible satellites on all APs,
    and these ones would have, say 10 tracked, and then 0 for hours,
    then 10.  It was hardly ever a gradual change.  We were convinced
    it was firmware, or a bad GPS receiver, or puck, etc. and went
    down every road we could think of, because it seemed like it had
    to be one of those.  Out of the 4-5 sites we had with this
    behavior, every one was permanently solved by pointing the pucks
    up, and I think all of them were in close proximity to a cell tower.

    No satellites doesn't sound like poor signal to me.

        We fought with losing GPS sync on ePMP APs at a couple of
        sites.  We had been told to point the pucks south to get the
        best GPS signal. There were several wild goose chases, as it
        seemed upgrading/downgrading firmware fixed it, but only
        sometimes.  In the end, the solution at each of these sites
        was to point the GPS puck straight up.  Our best guess was
        that there was something overloading the GPS receiver in the
        direction we had them pointed.  So pointing them up, while
        not giving them the best signal, minimized terrestrial
        interference.  At least that's our theory.

        Well, I did check the forums and found I'm not the only one.
        I'm going to try downgrading. Was hoping to find someone
        here who has gone through it so I dont waste time if it
        needs to be RMA'd :)

            It worked before, upgraded from 3.5.1, no more :(
