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 broadcast from towers in different directions and a single antenna can not accommodate all locations.
A rotator consists of two parts:
1. an indoor control unit
2. an outdoor drive unit.
The two are connected via a 3-conductor wire that carries the voltage and control signals from the indoor unit to the outdoor drive unit.
Channel Master manufactures a remote control unit, model 9521A. A separate indoor controller is also available, model 9537 and is compatible with the following rotator systems:
9500, 9510, 9510A, 9512, 9513, 9515, 9515A, and Radio Shack 15-1225.
Model 9537 is the indoor controller and handheld remote control. This model may be added to an existing manual rotator system and instantly upgrades the system to the remote control version. |
