<p>Remote control device for controlling the angle of inclination of the radiation diagram of an antenna. Said device make it possible to act remotely on the angle of inclination of an antenna and consists of two units, one of which is electronic (2) and the other mechanical (1), these units being physically separated and interconnected forming a single assembly wherein each unit has its own casing. Said mechanical unit has an electric motor, winding position sensors, driving pinion and toothed wheel meshed with said pinion. The electronic unit has connection terminals for power supply and communication, electronic board, sensor for reading the initial reference position, and casing. Both units are connected by cable and connector. The independent arrangement of said units makes a seated electric unit protected from humidity possible, the selective replacement of units and the visualisation of the position and movement indicator rod (3).</p> |
