First of all, Mitch, is that 100 foot aluminum crankup
rated for that kind of a load?  Not just in total square
footage, but also the additional stress put on the top
section by eight feet of mast and another large antenna?

Personally, I prefer steel crank-ups, as the aluminum *will*
fatigue over time from bending back and forth absorbing the
wind loads placed on it.
