MOBILE WIDE-BAND MAST ANTENNA Russian patent published in 2007 - IPC H01Q9/34 

FIELD: radio engineering; antennas for mobile high-frequency radio transceiving systems.

SUBSTANCE: proposed antenna has supporting plate mechanically joined with antenna mast and antenna operating curtains made of antenna strand and disposed along lines of two straight different-height cones joined through their bases. Top and bottom ends of antenna operating curtains are mechanically joined to top and base of mast; bend points of operating curtains are geometrically disposed on circumference of bases of two straight different-height cones; top and bottom ends of operating curtains are electrically interconnected through top and bottom slip-rings, respectively; bottom slip-ring functions as first feed point of antenna whose second feed point is formed by electrically interconnected ends of counterpoises uniformly disposed along antenna. Mast is supported in vertical position by means of dielectric guy ropes incorporating adjustment strips and clasps. Collapsible antenna mast has tubular metal base and elbows in the form of dielectric pipes mechanically joined together by means of metal inserts. Bottom elbow is built integral with base installed on antenna supporting plate. Antenna is placed in stowed position by separating mast elbows and their stowing in packet wherein antenna operating curtains are secured by means of clips and hooks and counterpoises are wound on base clips.

EFFECT: reduced closing-down and setting-up time at optimal electrical characteristics which is essential for arranging antenna fields.
