FIELD: radio broadcasting and data transmission. SUBSTANCE: first antenna at user's location receives signals at first frequency; these signals propagate only in first sector of directional reception counted from first antenna axis. The latter is directed so that direct satellite broadcasting signals transmitted from satellite on near-earth geosynchronous orbit could be received. Second antenna at user's location receives signals at first frequency; these signals propagate only in second sector of directional reception counted from second antenna axis. Second antenna is tuned to receive signals transmitted at first frequency from ground transmission point spaced at certain distance from user's location. EFFECT: provision for transmitting ground signals simultaneously with satellite ones at same frequency. 12 cl, 3 dwg, 1 tbl
