Abstract
RET antenna with a modular switching unit and a multi-device control unit con figured to be inserted into and removed from a receptacle in the antenna. The multi-device control unit works together with motors and position sensors located inside the antenna to allow a single controller located in the multi-device control unit to control multiple embedded electro-mechanical actuators, such as phase shifter control motors. The multi-device control unit includes lightning protection circuits, communications circuits, a motor controller, power control circuits and a motor position sensing circuit inside a small housing. These components are shared between all motors inside the antenna through the modular switching unit, which allows a single set of components within the multi-device control unit to replace redundant components deployed in prior RET antennas.
