BALANCED ROTARY SUPPORT Russian patent published in 2024 - IPC H01Q1/12 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment, namely to antenna rotary devices. Result is achieved by the fact that the rotary support device comprising at least two rotary mechanisms, each with its own axis of rotation, on one of the axes with the possibility of rotation in the elevation angle there is an antenna kinematically connected to the counterweight located opposite to it, counterweight is made transformable in such a way that the length of the lever arm of the counterweight can vary, differs in that counterweight is made in form of two single-arm levers with variable length of counterweight arm, which axis of rotation is symmetrical to the axis of rotation of the antenna by the elevation angle and is located below it, in the same vertical plane with it, on the support structure of the rotary mechanism, which is common for both axes, so that sweeping planes of single-arm levers do not cross areas of rotary mechanisms, and kinematic connection with antenna of each of single-arm levers is carried out by means of hinged parallelograms, wherein the length of each of the single-arm levers before the counterweight varies in direct proportion to the torque acting on the axis of rotation of the antenna by the elevation angle.

EFFECT: high-precision mobility of full-turn antennae with mirror diameter of up to 17 m and high stability.
