The Alliance Tenna-Rotor® consists of two units: the rotor unit, which mounts on the mast below the antenna, and the control box, which is placed on or about the TV receiver. These are interconnected by a four- or five-conductor cable. The theory of operation concerns two separate circuits. The first is the power circuit, which in all Tenna-Rotors® transmits the power that actuates the motor and rotates the antenna. The second is the indicator or signal circuit, which reports the roto ...
