FIELD: physics, radio.
SUBSTANCE: invention is related to radio electronics, namely, to antenna-feeder devices of decametre range. In adaptive antenna matching device arranged on the basis of matching circuit, in which inductances are connected serially, and between them there are three capacitances installed parallel: C1(i)=C(min), C2(i)=C(0), C3(i)=C(max), with the possibility of their commutation by means of control circuit on the basis of comparison by specified algorithm of voltages in neighbouring arms of every link in matching circuit, which is realised in comparators having negative threshold of actuation for connection of C1(i) and C2(i) and positive threshold of actuation for connection of C3(i), and between the last link and load there is additional wideband matching circuit (WMC) installed.
EFFECT: increased traveling wave factor (TWF) in radio transmitting track and increased width of match grip.
