An antenna of a tuner is provided to prevent the intermodulation characteristic between a first switching diode and a second switching diode. An antenna(ANT) of a tuner includes a first switching diode(D21), a noise preventing unit(20), a second switching diode(D22), and a capacitor(C21). The first and second switching diode discharge static electricity introduced from the antenna to a ground by being connected to the antenna. The capacitor is connected to the second switching diode in parallel to transmit a high frequency signal. The noise preventing unit prevents the interference or noise due to the intermodulation characteristic between the first and second switching diodes.
