Is my Antenna too big for my CM-9521? Weight Specification (CM9521A CM9521HD)

CM-9521A Weight Specification;
We really do not have a weight specification for the CM9521A rotator.
They were designed for antennas weighing ~15lbs along with a 3ft long X 1 1/2" diameter upper mast. Like many products, we're sure it was over-designed to handle more, but installing something other than ~15lb antenna may shorten the life... We still have many 25 year old rotators out in the field working fine with 15 lb antennas on them.
Also, make certain that you do not have an upper mast over 3ft tall. Too tall of upper mast creates too much leverage in windy situations and can wear on or damage the thrust bearing assembly.
