Abstract: A pedestal assembly for rotatably carrying a load containing radio-sensitive equipment is disclosed, with the assembly having a turntable and base. The profiles of the turntable and base adjacent to one another are both stepped and define a tortuous path between them. The assembly further is designed to distribute any attached load directly to a driven bull gear, rather than to the turntable.

Abstract: A satellite tracking antenna structure is disclosed which is adapted to be mounted at the head of the mast of a ship. The antenna itself, is provided with a reflector which forms one side of a box structure, which is open on the side thereof opposite to the reflector and has a rigidifying structure including an arched beam mounted in the box between the reflector and the open side of the box opposite to the reflector. Located within the box structure is a pedestal extending upwardly from the mast. A stable platform arrangement is mounted on the pedestal and the box structure is pivotly mounted on the stable platform arrangement so as to enable the antenna to be rotated in azimuth and in elevation in the direction of a satellite with which communication is desired.
