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.
A directional antenna mechanism of a mobile radio tracking receiver, comprising four antenna elements, which are fastened as articulated to a body of the radio tracking receiver, where electronic components and devices of the tracking receiver are placed inside the body of the receiver and where the antenna elements are turnable between an operating position in which they are pointed away from the body and a transport position in which they are placed substantially parallel to the direction of the longitudinal axis of the body, and where at least two antenna elements are connected to each other by a mechanism in a way that moving the first antenna element to the operating position or the transport position causes the second antenna element to move to the same operating position or transport position simultaneously.
