>  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.
