Abstract
A device for positioning an antenna on a vehicle. The device includes a first motor-driven timing belt connected to opposite sides of the antenna frame for rotating the antenna about its elevational axis. A constant force spring or a cam compensates for changes in belt path geometry as the antenna rotates. A second motor-driven timing belt is wrapped around a perimeter of a base plate for rotating the antenna about its azimuth axis. Electrical signals for the antenna and the drive motors are multiplexed and passed through a single coaxial cable in a rotary joint along the axis of azimuth rotation.
