Beschreibung
Zusammenfassung:	The proposed folding antenna device of a radar station contains a rotary platform, an antenna, which is installed at the platform, a drive for angularmovement of the antenna, and a crank-type transmission mechanism. For the purpose to reduce the height and enhance the reliability of the antenna device, the drive contains two hydraulic cylinders, which are pivotally connected to each other and to the crank-type transmission mechanism. The rotation axis of the crank-type transmission mechanism is arranged lower than the plane in which the longitudinal axes of the hydraulic cylinders are arranged. At the rotary platform, supports are installed that have slots in which the journals of the shaft of the connection of the hydraulic cylinders with the antenna and the latches of the journals are placed
