[TowerTalk] Rotator Swap U.S. Tower Crank-Up

[Tony]

All:

Not sure if this is the proper procedure, but the last time I replaced a 
Yaesu rotator on my U.S. Tower heavy-duty crank-up, I used the bolt 
that's built into the tower to hold the mast in place to kept it from 
from falling.

It seemed to hold 100lbs of antennas just fine, but was wondering if I 
should clamp the mast at the top above the bearing for a bit of insurance.
