PURPOSE: A gain distribution RF(Radio Frequency) relay system is provided to improve speech quality by preventing the oscillation phenomenon of a repeater by antenna feedback. CONSTITUTION: A previous relay device(200) connects to a base station(100), radiates a signal from the base station(100) in a predetermined direction to transmit the signal, and receives a signal transmitted from the predetermined direction. A last relay device(300) receives the signal from the predetermined direction, amplifies the received signal, and transmits the amplified signal to a plurality of subscriber terminals. The last relay device(300) receives the subscriber terminal, amplifies the received signal, radiates the amplified signal in the predetermined direction to transmit the signal.
