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 lubricant filled drive assembly is disclosed having an insert to displace a portion of the required volume of lubricant. The insert is shaped so as to receive interchangeable or optional pieces of drive assembly equipment, and when certain pieces of equipment are not used, plugs are added to the assembly to occupy the empty space within the insert. By eliminating any unoccupied space, the plugs alleviate the need for additional lubricant which might otherwise be a cost of adding flexibility to the gear drive. The insert and plugs are preferably coated with a lubricant impermeable layer.
