Default Heavy Duty Rotator

I have a Wingard HD8200P antenna mounted to a Channel Master Rotator on Top of a 40 ft Tower. Having trouble with the Rotator slipping. What Brand and Model of Heavy Duty Rotator would you guys recommend?

Thanks for all replies, Kevin

I have used an alliance rotor at my home with my 8200p for several years (14 years) without any problems. The control box is old style, nothing fancy.

give norm a call and he will help you select the right rotor for your needs.

This is the rotator that I have. It is the cheapest rotator with a brake. It's on a 120' tower.

Thanks Rick and Towerguy,

Rick I emailed Norm the rotorservice, waiting on his reply.

Towerguy I looked at the Rotator you suggested, that one was definately more than we want to spend. But I did see the AR-40 model for $289.95 and it says it has a brake. Do you think this one would be adaquate for my purposes? Thanks Kevin

I think TowerGuy LIKES his rotators! The AR-40 or the AR-22 will be fine for your situation. The sync issue is a very common problem with the Channel Master 9521a, and unfortunately, there isn't any real remedy for it. The CDE rotators are considerably more heavy-duty, however, and won't have the drift problem, although you may have to sync them occasionally. Unfortunatly, you will lose the remote-control function of the CM 9521a, though

Thanks Tigerbangs,

I noticed in the Channel Master Manual it shows how you can set it up to automatically re-sychronize after 50 uses. Maybe that would remedy our situation. Or do you think the the Channel Master Rotator is just to small for that large Winegard HD8200P Antenna?


Thanks again, Kevin

Yes, the AR-40 would work for you. The brake on the AR-40 is on the motor. The brake on the Ham-m is a part of the housing. The housing brake takes the load off of the gears.

If you are willing to live with the drift issue, the 9521a will work for a few years...since you have already made the investement, I suggest waiting until it dies before climbing the tower and making the change, that is, unless, TowerGuy is in the neighborhood...LOL!

Real Men" use Prop Pitch Motors
These motor & gearbox units were used on WWII and Korean War era aircraft for controlling the pitch angles of the propellers. The bullet shaped canister sticking out in front of the propeller houses the "Power Unit Assembly", which is what Radio Amateurs commonly refer to as the "prop pitch motor. " This unit is actually an electric motor plus a gearbox. Most of these units were made by the Curtiss-Wright Aircraft Co.
These things make very powerful and reliable antenna rotators when they are properly prepared...
These units are probably the highest quality mechanisms ever used to rotate amateur antennas, at least when first went into antenna rotating service.
The variety of methods used to adapt them to the task of rotating antennas has been quite varied. Some of the conversions that I have seen were quite nicely done. Others have bordered on gross mechanical malpractice. Many have been completey butchered, or converted in a manner that prevents one from dissassembling everything in order to rebuild the unit when it dies.

Just the thing when enough is not enough, and way too much is just right! Amazing stuff!
