Abstract
An orientation adjusting device for a satellite transmitting signal antenna comprising a housing inside of which an electromechanical actuation system comprising a worm gear-worm pair driven by a motor through a reduction gear set is disposed. A rotatable antenna seat which constitutes, in part, the housing is mechanically connected to the worm gear so as to be driven by the motor. The worm, of which one end is pivotally fixed on the housing, is biased toward the worm gear by biasing means so as to maintain a more precise engagement between the worm and the worm gear and to reduce the backlash associated therewith. Microswitches are provided inside the housing to control the rotation range of the antenna.
