Abstract
A common multi-purpose actuator to control antenna remote electrical tilt, remote azimuth steering, and remote azimuth beam-width control is disclosed. A single stepper motor uses a Hall-sensor for closed loop positioning feedback. Serial and parallel communications are employed through the same harness to the motor control circuit. The driven shaft of the motor turns a self-locking worm-gear which rotates a mating shaft which drives the necessary gearing. The actuator assembly can be arranged in multiple or single output configurations. DC line filtering improves the antenna signal to spurious noise ratio.
