John:
What some on TT have suggested is installing two angle irons from the
mast out to and beyond the tower legs. Use a muffler clamp to hold each
angle onto the mast and arrange them so each rests tightly against a leg.
In that way a heavy wind can't rotate the mast and antennas.
The second bearing shelf is nothing more than a support to keep the
mast from flopping over out of the tower once it's disconnected from the
rotator.
