> So the question - since the OR2800 can support a vertical load of
1800 lbs, do we just lower the mast/antenna until it is resting on
the rotor plate, tighten the clamps, and then tighten the eccentric
locking collar? Or do we lower it to an inch above the rotor plate,
tighten the eccentric locking collar, then tighten the clamps, so
there is no weight on the rotor?
Yes - the manual (at least the older ones) stated that the weight
should be on the rotator. The rotator needs the load to seat the bearings.
Besides, that UST bearing is for horizontal thrust, not vertical so it's not
going to do much anyway.
