发明名称 SATELLITE RECEPTION SYSTEM AND RECEPTION SIGNAL MIXER
摘要 PROBLEM TO BE SOLVED: To provide a satellite reception system capable of transmitting reception signals from a CS antenna and a BS antenna to a terminal side by using one transmission line. SOLUTION: The reception signals from the CS antenna 2 and the BS antenna 4 are mixed in a mixer 10, the mixed reception signals are transmitted to a branching filter 12 by one coaxial cable and the respective reception signals are branched in the branching filter 12 and outputted to a CS tuner 14 and a television 16. In a transmission route from the branching filter 12 to the CS tuner 14, a power unit 20 for receiving voltage signals (DC 11 or 15 V) outputted from CS tuner 14 for both polarized wave changeover and power supply and generating the voltage signals of a power amount capable of operating the respective antennas by the same voltage as the signals is provided and the voltage signals are transmitted to the mixer 10. The mixer 10 supplies the voltage signals transmitted from the terminal side to the CS antenna 2 as they are and converts the voltage signals to the voltage capable of operating the BS antenna 4 and supplies it to the BS antenna 4.
