Additional Information

A Rotor or Rotator is a mast-mounted, motor-driven device that permits the TV viewer 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 derived from broadcast towers in different directions and a single antenna cannot accommodate all locations.

A rotator consists of two parts: 1) an indoor control unit, and 2) an outdoor drive unit. The two are connected via a multi-conductor wire that carries the voltage and control signals from the indoor unit to the outdoor drive unit.
