I am a little behind on my email, so please excuse the late response to this
thread. I have always left a little room - 1/2 to 1 inch between the rotator
and the bottom of the mast. Obviously I suspend the mast by a thrust bearing
at the top of the tower. This facilitates rotator swapping - I just unbolt
the old rotator, tip it out the side of the tower, and swap in a new one. I
have had lots of experience with HamIVs over the last few years and just this
week completed a Yaesu 2800 swap - hopefully this will be completely overbore.
Anyway, the question - Since no one mentioned this ( leaving room between the
mast and the rotator) have I been engaging in a poor practice?
Thanks --
