FIELD: radio equipment.
SUBSTANCE: invention relates to radio engineering and specifically to HF antenna matching devices. Disclosed technical result is achieved by introducing new nodes: a second matching circuit, a receiver of signals of global navigation satellite systems with an antenna, a program recording unit with an external input, a control panel, a working frequency generator, three high-frequency switching nodes and a second broadband matching circuit.
EFFECT: technical result consists in reduction of total time of device setting due to introduction of operation of beginning of preliminary adjustment of device to next operating frequency during communication session at previous frequency, as well as reduced time for switching capacitances and circuits by using high-frequency switching nodes.
