Modern telecommunication aviation systems operating in the DCMV range should ensure reliable operation with a wide range of different types of antennas placed on aircraft. It should be noted that the antenna impedance parameters vary significantly from the conditions of their deployment and weather; the length and configuration of the antenna cable connecting the high-frequency output of the antenna coupler (ACS) and the antenna have a significant impact. These factors can negatively affect the traveling wave coefficient (KBV), the efficiency of antennas and the antenna-feeder path as a whole, which will lead to a deterioration in the quality and range of communication.

Therefore, the coordination of radio frequency feeders with antennas of various types in a wide frequency band of the DCMV range is the most important task that arises when building an antenna–feeder path of radio stations, the solution of which is necessary when developing promising telecommunications systems. The reliability of information transmission and the range of communication, the weight and dimensions of onboard radio stations and radio communication complexes directly depend on the solution of this problem.

The article presents a block diagram and describes the method of matching and the algorithm of operation of a universal antenna matching device of a distributed type designed to match different types of on-board antennas of the DCMV range.
