ABSTRACT:
The central part of the nut of a gimbal mounting system for rotating a microwave antenna and the like is given a movement of elevation about the second axis (5) when the corresponding motor (II) is started-up and a circular movement about the first axis (3) orthogonal with the second axis when the corresponding motor (I) alone is started up, said circular movement automatically producing a movement of elevation about the second axis.
