Not quite:

I just finished erecting one of the model 5000 Hy Gain dual tower systems
in the back yard, with the R-3503 rotator.  Rotor specs are impressive. 
Rotating torque: 23,700 inch pounds, Braking torque 60,000 in. lbs., and
maximum vertical load 20,000 lbs.  It uses a 3/4 HP gearhead motor
driving another gearbox, which drives a sprocket for a 1" wide chain to a
huge sprocket around the thrust block as the final drive.  The specs say
0.5 RPM, but I timed mine around in 30 seconds.  I have only a dinky
Sabre MLP-1 antenna on it, and am looking for an AS-3515, AS-2187,
AS-3642, AS-3482, or LPH-89 or any other 3.5 - 30 MHz LPA to replace it.
