FIELD: antenna equipment.
SUBSTANCE: invention relates to automatic conversion circuits input and/or output resistance antennae. Device comprises central processor (1), transceiver (2), flash memory (3), relay drivers (4), switched relays, analogue-to-digital converter ADC (5), bidirectional coupler (8) made in its secondary lines with two detectors for measuring incident and reflected waves. Device also comprises phase detector (9) PD and meter (10) of power MP. At that, central processor (1) is configured to provide SWR calculation, its dispersion, average SWR, noises in radio frequency transmission channel from transceiver to transceiver antenna and calculation of impedance of transceiver antenna.
EFFECT: reduced SWR, wider range of operating frequencies from 1½ to 30 MHz at power of supplied radio-frequency signal to 100 W.
