Abstract
A passive, active or mixed platform type antenna orienting apparatus mounts on a vehicle such as a small-sized vessel or an automobile, which is subject to turns and complex vibrations, traces a target such as a communications satellite with a directive antenna. Between a rotational shaft connected to a platform supporting an antenna and a stationery shaft connected to base to be carried on a vehicle, there is interposed as electric rotary coupling for transmitting power and signals necessary for a transmission signal and an attitude control, so that the platform 43 supporting the antenna 1 may continuously rotate with respect to the vehicle 27. Midway of a post 41, moreover, there is disposed a horizontal damping mechanism 70 which includes a laminate 75 and facial pressure apply means 76 for applying a facial pressure to a laminate 75, to effect a damping action which is excellent in durability and even in the horizontal direction.
