Antenna Rotator System – Heavy-Duty Outdoor Drive Unit, Indoor Control Box, Rotates Preset Positions from 0° to 360°, Supports TV Antennas and Ham Radio Mounting Poles/Masts up to 1.75" Diameter

This is the one you want for large single or combo TV antenna installations. Heavy duty cast iron. Works great with 5 foot mast. Only use the RCA one for small antennas. Used a HOPKINS 05064 large resin black funnel to make a rotator umbrella to protect the unit from the elements and extend its life. Just cut end of the funnel with a hacksaw and grind or file the end hole until it fits snugly on the mast before placing the mast on the rotator and then glue or tape the funnel to mast directly above rotator. Don't suddenly change direction of the rotator before it reaches its coordinates or its calibration will be thrown off. I found the automatic recalibration made my rotator's coordinates even more off than it was after doing this. It's best to manually recalibrate the rotator by rotating it clockwise until you visually observe it at either due east, west, north or south regardless of what the control box reads. Then pull the 3 wires out of the back of the control box and set the control box coordinates to match your visual observation. Clockwise 0 degrees north, 90 degrees east, 180 degrees south, 270 degrees west or 360 degrees north. Then reinsert the 3 wires into the back of the control box and it will be calibrated.

I wanted a VERY reliable rotator for an antenna 'stack' I have. First thing I noticed is this has a pole length restriction of 3 feet out the top of the rotator, which is not surprising since the pole does NOT go thru the rotator like the old models - the pole sits on the top of the unit. I have a round 'omni' antenna at the top of the 3 foot pole with a 12 foot long 1970's antenna approx. 8 inches above the rotator unit itself. Since this is a ChannelMaster, I will expect a long life from this unit. EXTREMELY well constructed unit. Relatively easy install, excellent instructions.

Works well with large TV antennas. The remote control feature allows me more viewing enjoyment. A signal can and does shift. I can adjust position easily. It also handled my 10 meter Ham Radio five element 10 meter Yagi. I will probably purchase one more for my ham station at our beach Cabin

Easy install and works as it should. Had only one problem where it rotated 360 on testing before putting it up with no issues then would not reverse direction. Found one wire not making good connection then all worked fine.

Made in China !!! Time and weather will tell of performance and durability.........I've had fantastic luck with the 9512 in the past. Now CM has sold out the American people to China....... 3 Stars till further notice.......

When I first installed this unit. It would turn about 90 degrees and stop. I had to use a wrench to get it to make a full turn. I did this several dozen times and now it has loosened up enough to turn on its own. I can still hear the brake dragging so I am not sure if it will keep working or if it is going to die on me.

I used this roter to turn a lightweight magnetic loop antenna. It was easy to install, works perfectly, and has every feature I could ask for. And at a good price.

Received two units, both bad. Purchased numerous items from CM and have had numerous issues with four items to date. Four items out box bad. Now another item has failed in less than a month. CM wants to charge me for shipping. I use to install Over The Air Systems (OTA) for a living. but that was when all there products were made in USA. It seems they have a severe quality control problems. Obviously CM doesn't care about customer service, nor are they willing to accept responsibility for their products. Sad, I had such high hopes for my 48 foot tower.

The unit is well made with a better controller than the previous Channel Master I had. This is a good unit for the recommendations given. I am sure it will out last the cheaper units.

I like the way it will turn the antenna easily in both directions when I need to .
