Does anyone know the wind load rating of the Wilson  WR-500 antenna rotor. I can not find any useful information on the net.

I THINK that Wilson put their name on the Allied HD-73 rotor, but this is coming from "way back" in the memory cells.  I could be mistaken!

W7FG has the manual for $5.  Cheap!

This answer was provided by Chuck, N4NM to an identical question posted by Kurt Andress, K7NV on behlf of another amateur -
Tower Talk on contesting.com Sunday, 1 August, 1999

From the WR-500 manual:

    Max. Load:          6 sq. ft. windload
    Motor torque:       780 inch-pounds (stall torque)
    Brake type:          Disk
    Brake torque:       1300 inch-pounds
    Gears:                 Stainless
    Bearings:            96 ball bearings; 750 pounds balanced weight capacity

There's more, but that's most of the important stuff. Be wary of wind load specs ... I would pay more attention to the torques, and compare these with modern rotators which also give things like "K-factors" just so you can compare "apples with apples".

If you want anything specific, or a copy, let me know.
The manual has a good schematic, too. This thing bears a striking resemblance to the current Yaesu family of rotators.

If I remember correctly, I tried the rotor side connector with my G-800 cable, and found that it mated. The control box, however, is totally different.  DO NOT try to mix & match!  
The Wilson rotator uses an A.C. motor, while the Yaesu series uses D.C. motors.

Wilson rotors are VERY VERY hard to find parts for. The rotators are their own kind and Wilson didn't copy any other companys design. I myself, have never seen one at any hamfests or on Ebay.

I bought this rotor on ebay as it once long ago ... The rotor is in a satisfactory condition, lubrication required, and the control unit was broken direction indicator (arrow). I bought a Chinese "no name" indicator, suitable in size, changed the scale and everything works.
Using a rotor on a low mast, the thrust bearing is, rotating them homemade squares (2 ele.) on the CB, and 50 MHz. And also - VHF / UHF (4/7 elements). No Problems. Tongue
