VHF ANTENNA-FEEDER DEVICE Russian patent published in 2023 - IPC H01Q9/28 

FIELD: antenna technology.

SUBSTANCE: invention relates to antenna technology and serves as a receiving and/or transmitting VHF antenna when placed on stationary objects. The effect is achieved by the fact that the antenna-feeder device of the VHF range contains a coaxial feeder connected to a conical radiator, a counterweight and a broadband matching device (BMD) included in the gap of the coaxial feeder. According to the invention, the counterweight is made in the form of parallel upper and lower metal plates connected by means of fasteners, while the lower plate is placed in a concrete base, in the upper part of which a recess is made in which the upper plate is placed, with an insulator fixed to it by means of fasteners, in the upper part of which is fixed a conical emitter made of steel, under the top plate in the concrete base, a central vertical channel is made in which the BMD is placed, and the coaxial transition from the conical radiator to the BMD is passed through a vertical channel made in the central part of the concrete base, and from the BMD a feeder is laid to the transceiver through the hole made in the bottom plate.

EFFECT: increasing the protection of the antenna from climatic and dynamic influences, including shock waves.
