Abstract

A tuner is provided to connect a main tuner and a sub tuner directly through a connector without a cable, thereby preventing loss and input of noise due to use of the cable. A tuner comprises a main tuner(21) and a sub tuner(22). The main tuner distributes a high-frequency signal to inside and outside. The sub tuner converts the high-frequency signal, which is distributed to the inside, into an intermediate-frequency signal. The main tuner is directly joined and connected to the sub tuner. The main tuner includes a chassis(211), an antenna input terminal(212) formed on an upper surface of the chassis, and an output connector(213) formed on one side surface of the chassis. The antenna input terminal is coupled with an outside antenna to receive the high-frequency signal, and the output connector outputs the high-frequency signal, which is distributed to the outside.
