An elevation mechanism for a satellite antenna system. The elevation mechanism includes tilt links or arms, lift links, and a linear actuator with an adjustable length leg arrangement. Each tilt arm is pivotally mounted at its inner and outer end portions to the base or azimuth plate of the system and to the back of the dish of the system. Similarly, each lift link is pivotally mounted at its inner and outer end portions to the base and to the back of the dish. The linear actuator in turn is pivotally mounted at its inner end portion to the base and at its outer end portion to the lift links. In operation, the linear actuator can be moved between extended and retracted positions to cause the dish to move between its stowed position facing downwardly and a deployed position facing upwardly of the horizon at a targeted satellite.
