TELESCOPIC MAST Russian patent published in 2019 - IPC H01Q1/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna devices, in particular, to retractable telescopic masts used in mobile radar installations. Technical result is achieved by using in the design of a telescopic mast a lock with an increased number of closed points of the hook on the perimeter of the cross section of the above section of the claimed mast due to creation of mutual closure through the side cylindrical surface of the spring-loaded rod, fixing the extended section of the mast and simultaneously releasing the seat of the above-positioned section at deployment of the mast.

EFFECT: excluding wedging of mast sections with violation of order of sections extension, elimination of additional loads in sections from concentrated moments in points of lock hooks, improved reliability of connection and retention of superposed sections with underlying section in axial direction and absence of requirements for accuracy of mutual location of sections along angle about axis of mast.
