I passed this info on but in the mid 70's K4SB (Then K4DJC) has an article
in either ham radio or 73 about mounting an extension pole out the top of a
tower using a rotating bearing so that the dipole or any wire antenna would
stay in one position while the top section rotated. This would also work
with the rotating tower version.
The key is to get the extension long enough to clear the beam below. In
K4SB's case this was 17 feet. The article is cross-referenced in either
the ARRL antenna book or the ON4UN book or both.
What better way to get the dipole or inverted V higher in the center!
