Abstract: PURPOSE:To obtain an excellent communication system even when a reception level has less margin by providing a low noise amplifier near an antenna. CONSTITUTION:The low noise amplifier 2 is placed at a location possibly near the antenna 1. A branch circuit 3 branches a microwave signal received by the antenna 1 to the low noise amplifier 2, the amplified reception signal is coupled to a feeding line 4 and transmitted to the receiver of a radio transceiver 5.
