I can see you're confused about the terms. Wind loading is the force exerted by wind when the antennas and mast are stationary. The more wind, the greater the resistance if you try to turn the antenna using the rotor. That's total wind loading. Ice loading is the same concept. Enough ice can build up on the antennas and mast to cause problems for stationary antennas. Trying to rotate the mast when the rotor may be frozen in position and the ice load may be up to several hundred pounds, depending on the thickness, can quickly lead to bent masts or a burned out rotor. In addition, I have no idea what the horsepower or Kw rating of that rotor is, not to mention it's off center.
My son is a structural engineer and he calculated out exactly what I'd need to put up for a 50 foot tower with a similar mast and rotor. Wind loading here is the bigger issue although we do get some ice. Ice and wind loading have to be more of an issue is Michigan. That convinced me an attic mount would be a far more cost effective idea. If I could get the total weight of the tower, mast, antennas, and the power rating of the rotor, as well as the exact height and surrounding terrain conditions, I'm sure he'd be willing to run some calcs again.
