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 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.
