なることを特徴とする車載用アンテナアンプ。In a vehicle-mounted antenna amplifier connected between an FM/AM shared antenna and a radio receiver, there is an AM amplifier that amplifies the AM waves received by the antenna, and an AM amplifier that amplifies the AM waves received by the antenna. A switch that forms a path for guiding the output to the radio receiver, and also forms a path for guiding the FM waves received by the antenna directly to the radio receiver without passing through the amplifier when the amplifier is powered off. means, and the power source of the amplifier is connected to the FM/A on the radio receiver side.
An in-vehicle antenna amplifier characterized in that on/off control is performed in conjunction with M switching operation.
