<p>A motorized antenna mount for rotationally and pivotally supporting a satellite dish on a main vertical support pole. A base is adjustably mounted on the top of the support pole by a plurality of plumb bolts to compensate for any vertical misalignment of the pole. A motor housing is pivotally mounted on the base by a hinge and pair of curved pivot guide tracks. An electric motor is mounted in the motor housing and is connected to a drive gear through a gear reducer for rotating a turret which is mounted by a thrust bearing on turret mount attached to the top of the motor housing. The satellite dish is mounted on the end of a support arm which is pivotally adjustably mounted on the turret for declination angle control thereof. The turret has an internal arcuate-shaped gear track extending preferably 180.degree. about a central opening formed in the interior of the turret and engageable with the motor for rotating the turret drive gear. A pair of set bolts are mounted on the turret to pivotally adjust the declination angle of the dish support arm. The improved mount provides both course and fine pivotal adjustment for the dish supporting arm and particularly provides a motorized drive for rotating the dish to any desired rotational position for accurately positioning the dish for a selected satellite.</p> |
