ABSTRACT:
A control circuit for an antenna rotator includes a difference amplifier which develops a motor drive signal of both positive and negative polarity for rotation of a DC motor in both clockwise and counterclockwise directions. A feedback loop circuit for control of the motor is provided by a sensor of antenna position, the sensor being coupled between the antenna and the amplifier. Friction in a gear train coupling the motor to the antenna isolates the circuit from wind induced vibrations of the antenna.
