Yaesu ATU-450
Antenna Tuner

The Yaesu ATU-450 antenna tuner is designed exclusively for the Yaesu FT-450. This automatic tuner mounts inside the bottom of the transceiver. The impedance matching range is 16.5 to 150 ohms (up to 3:1 SWR). Accordingly the ATU-450 should not be expected to match long wire antennas. Please note that the ATU-450 cannot be used with the ATAS-120A. A clicking sound during tuning is normal.
