An antenna system comprises an antenna mounted on a vehicle, an amplifier for amplifying a radio signal received by the antenna, a light emitting part that converts the amplified radio signal into an optical signal and that outputs the optical signal, a fiber-optic cable that is installed in the vehicle and that is used for transmitting the optical signal, and a light receiving part that receives the optical signal transmitted through the fiber-optic cable, converts the optical signal to an electrical signal, and outputs the electrical signal.
