Overview

Our take on the Channel Master 9521A

For optimum reception of TV signals from more than one direction, it's hard to beat the combination of a good mid-range or long-range directional antenna and an antenna rotor like Channel Master's 9521A. This sturdily-built design can handle wind and weather for rooftop installations, and works great with attic-mounted antennas, too. You'll love the convenience of being able to control your antenna with pinpoint precision without leaving your chair.

This sturdily-built design can handle wind and weather for rooftop installations, and works great with attic-mounted antennas, too. You'll love the convenience of being able to control your antenna with pinpoint precision without leaving your chair.

The 9521A has three parts: the rotator motor, controller unit, and wireless remote control. The rotator unit attaches to your antenna mast, and a special 3-conductor wire connects the rotator to the controller unit (controller wire is not included). The controller unit is located indoors, away from the elements, typically near your TV. It has a digital display for channel and diagnostic info, and includes an AC power supply that powers the 9521A system. The supplied remote control is easy to use, and this system can also be operated using many universal remotes.

Rotor was everything we expected. It works wonderful!

    Features

    Overview: A Rotor or Rotator is a mast-mounted, motor-driven device that permits you to conveniently rotate (orient) the outdoor antenna in any direction to optimize reception of a desired TV channel. A rotor should be considered when TV signals are being broadcast from towers in different directions and a single antenna cannot accommodate all locations. The rotator consists of two parts; an indoor control unit and an outdoor drive unit. The two are connected via a 3-conductor wire (not included) that carries the voltage and control signals.

    Note: The control unit for the Channel Master 9521A is not backwards compatible with any of the older Channel Master rotors.

    Direction: The compass heading (direction) you want the antenna to point can be entered directly using the included remote, or you can scroll to the correct heading using the up and down buttons on the control unit (example: 90° to point east, 225° to point south-west, etc).

    Programmable: You can program 69 antenna locations (1-69), corresponding to 69 over the air broadcast frequencies. This way the antenna direction preset number can be the same as the channel number. The non-volatile memory will hold your programmed locations during a power failure.

    Synchronize: After moving back and forth many times, a mechanical device can become misaligned with its electrical controller. At any time you can Synchronize the drive unit and control unit. To realign, the motor turns fully counter clock wise and calibrates that direction to 0° (the orientation of the drive unit is fixed at installation). If you prefer, auto synchronization can be turned on and the system will realign itself after each 50 direction movements.

    Drive Unit: The drive unit uses a heavy duty motor in a one-piece cast aluminum housing with a durable powder coat painted finish. It uses a precision cut gear system, built-in steel thrust bearings, and has wind-tested brake pads.

    Please send tracking number Thanks [ Nelson  Nov 07, 2016 ]
    cause I need it .................replacing the nine year old unit [ elizabeth  Sep 26, 2016 ]
    No other choices [ BRIAN  Aug 21, 2016 ]
    recommended on several review sites [ Bob  May 03, 2016 ]
    we have had channel master before and this one had good reviews. [ Bernice  Mar 17, 2016 ]

    It does not. [ Dominick  Jan 23, 2016 ]
    No [ Jeffrey M.  Jan 16, 2016 ]
    No you must purchase the wire your self. [ Willikam  Jan 16, 2016 ]
    Yes but the wire is very rigid, should be stranded. [ Jim  Jan 16, 2016 ]
    No wire included. [ Chris  Jan 16, 2016 ]
    I was replacing the exact same unit that I had previously installed. Therefore, I did not need to run the "3 conductor wire". To the best of my recollection, it does NOT come with the wire. Hopefully this helps. Joel [ JOEL D  Jan 15, 2016 ]
    I am unfamiliar with the configuration of the 8 bay antenna, but usually length of the post that is used to support the antenna to the top of the 9521A determines the clearance. Hope that helps. [ JOSEPH  Sep 01, 2015 ]
    THe rotor mounts to your main mast and then you use a shorter mast to mount the antenna to. They recommend less than 5 feet for the second mast, but that should be more than enough to keep the rotor away from the antenna. [ David  Sep 01, 2015 ]
    Dennis: Even though the unit has a remote control, you still have to hardwire the indoor control box to the outdoor rotor unit with a three conductor wire ( read the product instructions). If you have no experience in electrical wiring you might want to hire a professional to install the unit. The remote control works on an infrared wireless signal and is pretty much line of sight from the indoor box to your remote control. I would suggest placing the indoor box close to your television location. Distance is usually limited to approximately 20 ft. as are most remotes for TV's, home theaters, etc. This is a good unit, have had mine for about a year now and no problems even in fairly high winds, 50 mph and up. Good Luck! [ ROY A  Apr 14, 2014 ]
    I've been as far as 30 feet away without a problem. I doubt it penetrates through anything solid. It did work through the glass of a patio door. [ STEVEN  Apr 14, 2014 ]
    Not our product. [ STEVE  Apr 14, 2014 ]
