Use of radio-relay lines is a priority, and sometimes - the only possible way to establish radio communications in geographically difficult areas; if it is necessary to establish communications rapidly, none the worse for wire ones, in poor developed areas; if other communication channels are broken due to natural disasters. The purpose of this article is to develop solutions to improve stability of communication radio-relay lines applying the technique of space-diversity reception of receiving antennas. The approaches described can find application in establishment of radio communications in mountainous areas, including the Kyrgyz Republic and Russia (the Republic of Dagestan, some regions of the Northern Caucasus republics). To study efficiency of space-diversity reception application, ratio between the statistics of fading depth and the median level for single and diversity reception was analyzed. This statistics was obtained by measuring stability parameters at intervals (sites) of digital radio-relay lines in the Kyrgyz Republic over several years. As a result, statistical distributions of fading depth for high-altitude intervals of digital radio-relay lines under space-diversity reception were obtained; gain in the fading depth under space-diversity reception was evaluated; a more accurate method to measure fading depth under space-diversity reception was suggested.
