isn't the thrust baring right at the top of the tower, or at least very near
it, but inside the tower itself?
If the rotery dipole is three feet down from the thrust baring, and you have
ten feet of push up on the top of the tower...then how does your antenna
turn whilst being attached to a pipe inside the body of the tower? and why
not put it three feet above the thrust baring, or three feet from the top of
the push up?
yes, you were as clear as mud hi hi.
