Some thoughts, in order of potential benefit:
-- Be sure the antenna is weight and torque balanced. This
is by far the most common problem I see with antenna
installations. An antenna just a couple inches off the
center-line of the mast will place tremendous torque loads
on the mast if it is not torque-balanced for neutral torque.
-- Use Dave Leeson's "FlexDisk" solution between the rotator
and the mast. The flex-disk will take up much of the shock
torque load, reducing shocks on the rotator and its tower mount.
-- Longer masts will torque a bit as well, like a torsion
spring. Personally, I think this is very much a secondary
effect, compared to other potential improvements.
