Abstract: This microwave link connects a fixed set of electronic equipment to a mobile set of electronic equipment that can be shifted between two extreme positions, at least one of which is an operating position. The link is, for example, one between a radar transceiver and a radar antenna that can be retracted into a silo. It is constituted by a sequence of rigid rectangular waveguide elements hinged at their ends by means of hinges comprising at least one rotating connector formed by two rectangular-window flanges, fitted together and rotational movable with respect to each other. This rotational connector has two operational positions at 180.degree. with respect to each other where it can transmit microwave power and where the rectangular windows of its flanges coincide, and it assumes one of these operational positions when the movable electronic equipment is in the operating position.
