Oh, sorry, forgot to mention that. Yes, I'm talking about the long
mounting bolts and nuts. Haven't had a problem with the short hex head
bolts that mate the mounts to the antenna itself. Except you really need
to crank down on those. I tightened them to what I thought was good, but
then I could still give them a slight push or pull and they moved. So
I'm trying to tell the guys to make sure those are really nice and snug,
but try not to wrench too tight on the mast clamp nuts. They did that..
and they still seized.

OK, on the 450 sectors, my recollection is the elevation adjustments
are short hex head bolts that go into threaded inserts. If those are
seizing on people, I think I will just apply anti-seize goop (the good
stuff with nickel dust in it) to them before assembly since I do that
on the ground and there’s no need to touch the threads afterward.
The ones that clamp it to the pipe are wiz nuts on long threaded
bolts, those would be harder to use anti-seize on, and would be the
best candidates to swap out for bronze nuts.

Yup, same here. Had to peak out a Force110 link and couldn't break the
elevation nut loose, so we had to leave it a few dB off instead of
breaking it off completely and/or bending the mounting plate.

I've had several of the SS nuts seize on the ePMP Force110's... which

I would very much like to see Cambium switch to a different kind of nuts.

Have you actually experienced the SS nuts seizing? Maybe I’ve
been lucky, but I have not had trouble with that even after
years. I guess I should be putting anti-seize compound on them,
but it’s so messy.
Metric silicon bronze nuts look to be expensive, like in the $1
each range, to swap them out yourself. Which of the many nuts
would you want to be silicon bronze? Just the 4 that hold it to
the pipe? Or also all the ones involved in the elevation adjustment?

I've pulled two up the tower by hand at once and the tower guys
didn't complain, so they can't be that heavy.
What I really wish Cambium would do, or talk Laird into doing, is
replacing the nuts with silicon-bronze like LMG uses on their
stuff. Or just go to galvanized. The stainless on stainless
sucks. They're $500 antennas and I shouldn't have to go buy extra
shit for them.

Wish they made the sector mounting hardware out of
aluminum. You get
4 of them together and they weigh a ton.
