PROBLEM TO BE SOLVED: To provide a satellite signal reception system to excellently receive a mobile body satellite broadcast even indoor together with BS, CS signals by mixing the mobile body satellite broadcasting signal of a 2GHz band and receiving the resulting signal through one signal cable even when receiving the BS left polarized wave signal in addition to the CS, BS right polarized wave signals . SOLUTION: The satellite signal reception system applies IF conversion to the left polarized wave signal received by a satellite signal reception antenna 1 by using a 9.576 GHz local frequency, applies IF conversion to the received right polarized wave signal by using a 10.678 GHz local frequency, mixes and outputs both the received signals, mixes a mobile body audio broadcast signal of a 2 GHz band received by a mobile body satellite broadcast reception antenna 2 with the mixed satellite signal, receives the resulting signal indoor through one signal cable 9b, and connects the resulting signal to a re-transmission antenna 8 installed indoor, which re-emits the mobile body audio broadcast signal of the 2 GHz band.
