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.

A few things that would be nice is for a rotor to work in conjunction with your TV or even Channel Masters stream+ but it does not. I do find once you get it setup it does work fine you just have to have the channels pre-programmed in. I find the remote is a little slow on responses but everything does work as it is supposed to. I would like to see channel master work with TV manufactures to have an option to do a channel scan with a rotor function to be able to have all your channels programmed in at once.

My old Radio Shack rotor and controller gave out. I replaced it with this unit. It took about 15 minutes to replace the old unit. The 3 wire harness was already in place from the old unit and I was easy to connect it up. It is installed in the attic of a 2 story house. This unit is significantly quieter and faster than the old Radio Shack unit from 20 years ago. Being able to preprogram multiple antenna positions is very nice.

We'd had an older model (no remote) of this item that lasted a long time. A storm took it out. This one is easier to use. I love the remote. Husband says this is a quality brand. Would recommend and/or buy again. Please don't ask technical questions. I just place the orders. I'd suggest contacting the seller, if you have questions.

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

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.

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.......

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 .
