Brian, et. al.,

In addition to the other comments I would only
add that a flexible, braided strap from the top of the tower to the mast
at or below the first antenna boom provides a direct path for RF and helps
ensure that RF is not "inside" near the rotator.  It also
should reduce RF travelling through a thrust bearing at the tower top
plate.

73 & Good luck
