DEVICE AND METHOD OF APPROVAL OF A RADIO TRANSMITTING ANTENNA-FEEDER TRACT WITH ANTENNAS OF DIFFERENT TYPES Russian patent published in 2019 - IPC H03H7/40 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering, namely to antenna-feeder devices of the decameter and meter ranges. In the universal antenna matching device, made on the basis of a distributed type matching circuit, the inductances are connected in series, and between them three capacitances are connected in parallel with the possibility of their switching by means of a control device based on a comparison according to a given voltage algorithm in the adjacent shoulders of each link of the matching circuit, a second matching circuit of a distributed type operating in another sub-band of the working frequency range was additionally introduced, two high-frequency relays P1 and P2 on the input and output of the device and two presetting nodes operating in different sub-bands of the working frequency range.

EFFECT: technical result consists in providing the possibility of matching the radio transmitting antenna-feeder path with different types of antennas, reducing setup time, adjustment and debugging of ICS when replacing / changing an antenna type at the facility, as well as improving the SWR in the antenna-feeder path.
