TELESCOPIC MAST FOR RAISING AND LOWERING RADIO ELECTRONIC EQUIPMENT Russian patent published in 2013 - IPC H01Q7/00 E04H12/18 

FIELD: radio engineering, communication.

SUBSTANCE: telescopic mast includes a cable adaptor, having a helical or zigzag shape and centring guides; one end of the cable adaptor is mounted on a fixed knee and the other on an upper movable knee. The cable adaptor is mounted inside the knee of the telescopic mast coaxial with a forced lowering cable and interacts with it through the centring guides, one end of which is fixed on windings of the cable adaptor, and the other on the forced lowering cable with the possibility of moving along the forced lowering cable. The centring guides can be made in two versions, in the first of which the centring guides consist of two pivotally connected parts, and in the second the centring guides are made in form of a plate where two neighbouring windings of the cable adaptor are attached to one of the ends of the plate and one winding is attached to the other end.

EFFECT: completed structure of a telescopic mast for raising and lowering radio electronic equipment while ensuring constant electrical connection between the fixed part and the upper movable part of the mast, as well as protecting the cable adaptor from mechanical and weather effects.
