Abstract: A power mast for the automatic vertical elevation and retraction of various devices, such as an antenna mounted on a communications vehicle. The mast is cable-driven, having a plurality of individual telescoping sections which allow for an overall collapsed height the same as or only slightly higher than the tallest such individual section. The cable is threaded around a series of pulleys, and is driven by a motor. Constant tension is maintained in the system, so that when in its operating or "up" position, the device is held in a stable condition until retracted.

Abstract: Communications vehicle including a roof-mounted satellite dish that is effectively and efficiently supported by a combination of structural components so as to allow for the maximization of operator compartment space in the vehicle without a concomitant increase in vehicle dimensions. A plurality of racks for housing electronics, access to which is required from the vehicle operator compartment, are designed as structural supports, in combination with other structural components, for the satellite dish and aimer assembly. The combination transmits the satellite dish and aimer assembly load through the structure and finally to the ground.
