[TowerTalk] Fw: Rohn 45 Question

[Gene Smar]

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.
