Not sure if this has been mentioned, but one alternative choice is to
mount a rotator on a hinged flange near the base with a mast going up to
a V-bracket near the top of the pole.
A line could be put through a pulley at the top of the pole to
raise/lower the mast, allowing you to change/adjust the antenna on the
mast top.
The V-bracket should have a way to maintain pressure/contact with the
mast without destructive friction forces. Perhaps by having a
'bearing-like' device at the point of contact?
Another possibility is to have a 4x4, attached to the pole with a hinge,
and mount the antenna/mast/rotator to the 4x4. The line going over the
pulley can then raise/lower the 4x4 with antenna, etc ... attached.
