RET antenna with motor and clutch assembly that is operative to mechanically disengage the DC motor and drive unit (also called the gear-motor unit) from the phase shifter adjustment shaft during a manual tilt operation. Disengaging the gear-motor unit removes the drag of the motor and the high gear ratio gear box from the phase shifter control rod making it easier to manually turn the phase shifter control knob. In addition, the clutch disengages the gear-motor without disengaging the position detector from the phase shifter control rod so that position calibration is not lost during manual tilt adjustment. When the manual tilt operation is completed, the mechanical tilt clutch enables the gear-motor unit to be reliably re-engaged with the phase shifter control rod for motorized electrical tilt operation without having to re-calibrate the position detector.

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.

A phasing element and an antenna including at least one such phasing element. The former is intended for inserting a variable lag into the transmission of an electric signal by variation of the electric path travelled by the signal in this element. The phasing element includes an input transmission line and an output transmission line, the lines being printed lines placed at the surface of a printed circuit. It also includes a mobile radioelectric coupling member, input and output transmission lines, which includes a first arm and a second arm. The electric path shows a variation field between a first position where the first and second arm cover respectively and entirely the transmission lines thereby defining a minimal electric path, and a second position where the first and second arms are respectively placed in the alignment of the transmission lines thereby defining a maximal electric path.
