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.
