<p>The indoor antenna according to the present invention is provided with an antenna part, and a support part for supporting the antenna part and installing same indoors. The support part is provided with an input terminal, an output terminal, an amplifier circuit, a pass-through circuit, a pass-through path switching unit, and an input source switching unit. The pass-through path switching unit switches the pass-through path that the reception signal passes through to reach the output terminal, to either an amplifier circuit or the pass-through circuit. When the pass-through path is switched to the amplifier circuit by the pass-through path switching unit, the input source switching unit switches the input source of the reception signal input to the amplifier circuit, to either an antenna element within the antenna part or the input terminal.</p> |
