FIELD: antenna engineering. SUBSTANCE: device has supporting metal structure mounting cardan joint with rod holding counterreflector installed in it. Rod is mounted for turning about center of turn located on focal axis of mirror antenna. Center of turn is geometrically aligned with point of intersection of mentioned cardan joint axes and center of gravity of rod carrying counterreflector. Cardan joint axes are oriented so that one of them is parallel to axis of elevation of mirror antenna. Rod is kinematically linked with operating mechanism of counterreflector. Operating mechanism is built up of two linear-displacement drives each mounted on supporting metal structure by means of respective cardan joint and hinged coupling with rod on its end opposite to counterreflector. EFFECT: simplified design of device and improved accuracy of counterreflector positioning. 4 cl, 5 dwg
