Howdy, TowerTalkians --
    There was a recent rotator discussion where a  poster determined the 
loading that included a mast. The relative formula (weight  times turning 
gives Effective Moment (Hy-Gain) or K-Factor (Yaesu). This  is a much better 
way to look at it than the old square footage estimates but  even this is an 
estimate. An educated one, but an estimate nonetheless. 
    Throwing in the weight of the mast threw the  numbers off significantly. 
When it comes to rotator capacity, the mast is a  non-issue. You don't add the 
mast weight in - just the antenna  figures. 
    There's no problem including the mast. (weight  80#  times turning radius 
of 1" = 13.3 foot/lbs) The mast has no effect on  the rotator capacity.
