<p>The invention concerns a powered device with two satellite antennae orientation positions. The system consists of a sleeve (5) fixed on the antenna support mast (2) whereon rotates a mobile tube receiving a conventionally fixed single antenna head, the mobile tube integrating the gear motor (13) ensuring its rotation and the switch and control electronic unit (13) for controlling a standard satellite receiver (18) without using either a positioner or additional power source, or supplementary cable, two mechanical stops adjusted by the installer, each on one satellite determining the two possible antenna positions. The system is designed to be associated with dish antennae generally used for receiving signals transmitted by geostationary-orbit satellite, and particularly for receiving television broadcast, whether for professional or domestic installations.</p> |
