ABSTRACT:
A steerable antenna system for adjusting the elevation of an antenna for communication with a central facility via a satellite. The steerable antenna system includes a motor, a spindle drivingly engaged to the motor, and a chassis fixedly disposed on the spindle. The chassis has a stop disposed about its periphery. A first waveguide is fixedly disposed on the chassis and a second waveguide is disposed on an antenna. A ring cam is mounted on the chassis, and a grooved is formed in the ring cam. A first portion of a lever arm is pivotally mounted on the chassis and a second portion of the lever arm is disposed in the groove of the ring cam. An antenna is hingedly mounted on the chassis and to the lever arm. A solenoid, disposed on a base of the steerable antenna system, is configured to engage a portion of the ring cam. In use, when the solenoid is activated, power from the motor is used to adjust the elevation of the antenna. When the solenoid is deactivated, power from the motor is used to adjust the azimuth of the antenna to acquire a satellite.
