VHF BROADBAND ANTENNA Russian patent published in 2018 - IPC H01Q9/30 

FIELD: radio engineering, communication.

SUBSTANCE: antenna contains a mast made of telescopic hollow sections, the upper section of the mast is made of a dielectric material, metal umbrella pins are mounted around its mantle, which are pivotally mounted in a vertical plane, the lower part of the metal pins being connected to a high-frequency feeder located inside the mast. The antenna also comprises a metallic vibrator configured to be connected to a high frequency feeder. The metal vibrator is located inside the mast, its lower end is fixed to the insulator and is located in the lower section of the mast, and the upper end is vertically displaceable within the upper mast section of the dielectric material.

EFFECT: ability to quickly deploy an antenna on a mobile object, including when driving in conditions of high wind loads, the frequency overlap factor K is significantly increased at the same linear dimensions of the antenna mast.
