Abstract
A directional antenna mechanism of a mobile radio tracking receiver, includes four antenna elements pivotably fastened to the body of the receiver. In use, the elements are turned to an operating position, in which they are pointed away from the body. After use, the elements can be turned to a transport position, in which they are placed inside the body in the direction of its longitudinal axis. At least two elements are connected to each other by a mechanism such that moving the first antenna element to the operating transport position also causes the second antenna element to move to the same position simultaneously. The mechanism includes a movable transmission rod inside the body, with toothings and toothed discs fastened to the ends of the elements, contacting the toothings. The rod is moved either manually by a lever fastened to the rod or by an actuator arranged inside the body.
