PURPOSE: A multiple routes relay apparatus and control method thereof are provided to increase the survivability of a rebroadcasting apparatus by increasing available channels through various connection configurations of a channel card unit. CONSTITUTION: A low noise amplification unit(220) is composed of two low noise amplifiers which receives a signal from a reception antenna(210) and transmits the signal to a channel card unit(230). The channel card unit is composed of one or eighteen channel cards and receives the signal from the low noise amplification unit, and to transmits the signal to a gain control unit(250) by receiving the signal from the low noise amplification unit. The gain control unit is composed of two gain controllers which transmit the signal to a high output amplification unit(260). The high output amplification unit is composed of two high output amplifier which outputs the signal through a transmission antenna(270). |
