Abstract
A method is proposed for determining the boundaries of the maximum largest zone of stable radio reception in the UHF/VHF range using beam antenna system under the action of several sources of radio interference located at different altitudes. The increase in the size of the stable radio reception area is ensured by the optimal orientation of the antenna arrangement at each point in azimuth and angular altitude using the radio communication channel model. To determine the coordinates of the map points belonging to the boundary, a modification of the wave algorithm is proposed. The conducted experimental studies for the MototrboTM DP4800 and Kenwood TK-8302 radio equipment allow concluding that the theoretical positions and computer simulation analysis results obtained are reliable.

Summary
An important area of research in current conflicts is the confrontation of electronic systems. In the context of the rapid development of electronic warfare (EW), a set of urgent problems arose in the field of providing necessary indicators of the stability of communication systems, in particular noise-resistant and electromagnetic compatibility (EMC) of electronic means. The relevant objective is to determine the boundaries of the area of noiseresistant radio communication with a maximum size. Potential existence of several interferers, as well as a possibility of using screens and directional antenna systems for protection radiotelephony means from the effects of such sources should be used in calculations. It is necessary to obtain a simple and effective method for calculating the boundaries of the maximum area of stable radio reception in the UHF/VHF band for mobile radio communication equipment under conditions of radio interference system. Knowing the threshold signal-to-noise ratio SNRmin, as an objective assessment of the level of protection of the radio receiver against interference, we can take the coefficient of suppression of the useful signal power by interference with a known limit (threshold) signal-to-noise ratio [10]: Ksup
