[TowerTalk] Rotator Loop

[Pete Smith]

How about this - turn the rotator to its clockwise stop.  Then wind 3 turns 
of flexible coax loosely around the mast, also in a clockwise 
direction.  As the mast rotates, the coax turns will loosen, but the 
rotator loop will always be supported by the mast.

I would also suggest cabling from your feedpoint in to the boom-to-mast 
plate, and having a connector there.  Make your rotator loop a separate 
piece.  That way you won't need a crane if there is a next time.
