A problem of autocompensators are actual not only for tropospheric-scatter communication (TSC) systems [1–5]. Due to the complexity of is solving [1–3] the present paper considers only the one theoretical aspect of the problem of quick fading autocompensation in TSC system, namely, that one that concerns the formalization of the correlation between quick fading margin and antennas gain loss ΔG_GA in order to stabilize automatically a standard power fading margin in TSC systems [1–3].
