FIELD: radio engineering. ^ SUBSTANCE: rotation drive of external frame of cardan suspension is rigidly attached to external frame and kinematically connected to gear wheel fixed in unmovable manner on antenna base and coaxially to rotation axis of external frame; rotation drive of internal frame is fixed on internal frame of cardan suspension and its output gear is kinematically connected to gear wheel fixed on external frame of cardan suspension and coaxially to rotation axis of internal frame; besides microwave elements of the path are arranged on the base and inside internal and external frames of cardan suspension. Invention allows optimising stiffness properties of kinematics and positioning accuracy of controlled drives. ^ EFFECT: increasing scanning angles and improving antenna reflector balancing. ^ 3 dwg
