FIELD: weapons and ammunition.
SUBSTANCE: invention relates to homing systems, particularly to antennae with mechanical scanning beam, and can be used on mobile objects, for example, in small-size active radar homing heads at final path to target. Summary: antenna device includes base, mirror, gimbal consisting of external and internal frames, outer frame turn drive output gear is articulated with gear wheel installed coaxially with rotation axis of outer frame, drive of rotation of internal frame, output gear is articulated with gear wheel fixed on the outer gimbal suspension frame coaxially with the axis of rotation of internal frame, and UHF circuit. At that, UHF circuit and cardanic suspension internal frame turn drive are installed on lower part of the mirror, forming cardanic suspension internal frame, outer frame turn drive is installed on antenna base, and outer frame gear wheel is fixed on azimuth shaft of cardanic suspension, wherein intersection of cardanic suspension frames axes of rotation coincides with mirror centre of mass. Cardanic suspension outer frame gear wheel is made in form of sector with through holes along sector arc.
EFFECT: technical result: improvement of balancing of movable antenna mirror with UHF circuit on it.
