PURPOSE: A device and a method for receiving signals of multi band are provided to receive satellite broadcasting receiver of Ka band and satellite broadcasting receiver of a Ku band at the same time. CONSTITUTION: A second receiver(120) receives a satellite broadcasting signal of Ku band. The second receiver performs amplification and frequency conversion of satellite broadcasting signal of the received Ku band. The second receiver generates the second signal. A DACU(Dual Antenna Control Unit)(130) synthesizes a signal which is a remainder substitution of the first signal which excluded the second signal and generated second signal. The DACU generates a third signal. The DACU transmits the generated third signal to a set up box. |
