SHORT WAVE BAND OMNIDIRECTIONAL ANTENNA Russian patent published in 2018 - IPC H01Q11/10 

FIELD: physics.

SUBSTANCE: invention relates to antenna equipment. Antenna contains an antenna-mast device, antenna elements, each of which contains a guide rope made of steel cord, sectioned by insulators, which upper end is mechanically connected to the top of the antenna-mast device, the guide rope lower end is mechanically connected to the guide rope anchor. Distribution feeder is mechanically connected to the posts, connected to the vertical asymmetrical vibrators lower ends, which upper ends are mechanically connected to the corresponding sections of the guide rope through the additional insulators. Distribution feeders inputs are the inputs of the antenna elements. Feeders are located horizontally above the underlying surface formed by the system of placed on the ground wires. It also contains three antenna elements, which guide ropes ends are evenly distributed around the circumference in 120°, in each antenna element, two additional guide ropes are inserted, made of a high-strength dielectric harness and connecting the top of the antenna-mast device with two additional anchors. Band vibrator made of an antenna cord in the form of two - first and second triangular isosceles frames, located at a certain distance from the largest vertical asymmetric vibrator from the antenna element in a plane perpendicular to the distribution feeder arrangement and vertical asymmetrical vibrators, wherein each of the band vibrator triangular frames upper corners are mechanically connected to the respective additional guide ropes, adjacent sides of the frames: downstream side B of the first triangular frame and the rising side A of the second triangular frame are electrically combined and connected to the corresponding wire of the two-wire feeder, to which second wire the middle of the wire is connected, electrically connecting the third, horizontally placed over the underlying surface, side C of the band vibrator triangular frames.

EFFECT: technical result consists in increasing the mobility and speed of antenna deployment, as well as increasing the efficiency of radiation / reception of radio signals.
