FIELD: physics.
SUBSTANCE: antenna device with the bigimbal support made in the form of the two gimbal supports consisting of the outer and inner frames, contains rotate drives of the outer and inner frames arranged on the fixed base, a microwave path, a mirror mounted on the inner frame of the first gimbal support, and a mobile and console-based mounted rod, on which a plug is fixed, cinematically connected with the yoke (arc), the ends of which are fixed on the drive of the inner frame. At the same time the rotation axis of the outer frame of the second gimbal support is parallel to the base plane characterized in that the inner and outer frame of the gimbal supports are respectively connected by two rods mounted symmetrically to the rotation axis of the rod mounted on the shaft of the outer frame of the second gimbal support on its outer side and on the symmetry axis of the outer frame. The axis of the yoke drive (inner frame) crosses the rotation axis of the outer frame of the second gimbal support perpendicular to the base plane, and the yoke plug shaft is movable in the symmetry plane of the rod at the angle to the symmetry axis of the outer frame of the second gimbal support, and the plug is adapted to be pivotable relative to the axis of the cross yoke section, and a torsion spring is mounted on the plug shaft, one end of which is fixed on the rod, and the other on the plug.
EFFECT: increase of the arrangement density of the antenna device symmetrically to the construction rocket axis, improved balancing and increasing of the view field of the mobile antenna mirror.
