I have a Cornell Dubilier AR-22R rotor that needs rebuilding before it
will run properly. It has bearing problems. I've found
rotorservice.com. They seem to be out of touch for the holiday week.

They describe it as follows: "AR-22 Rotor and Control - Designed to
rotate large television antennas. Will support stacked arrays and deep
fringe area antennas. Good for 3 sq. ft. of wind load." If they had a
rebuilt one in inventory they would be asking $249 with the control
and $199 without. I plan to have a large FM antenna on the same mast
~4' below the UFH.

Has anyone successfully used an analog control rotor like this one? It
appears to rotate in increments of one degree. Is this accurate enough
to get good UHF HDTV reception on a directional antenna like my Archer
Model U-75R? I am 28 miles from the Mt. Sutro tower. TVfool reports
that I have a line of sight available here in Palo Alto.

Thanks,
