Features:
*Mini shortwave automatic antenna tuner, Type-C charging port, OLED display.
*The antenna tuner is automatically tuned without any control wires and is suitable for most broadcasting stations.
*The device contains a set of 7 capacitors and 7 inductors, enabling it (with the maximum configuration) to work effectively in a wide frequency
overlapping with the amateur radio HF of 1.8-55MHz.
*Using metal shell, stable and reliable performance.

illustrate:
1. Connect the radio-ATU antenna tuner-antenna
2. When using for the first time, please set the output power of the radio or power between 20-30W, warn that high-power tuning may easily damage the antenna tuner.
3. Set the radio mode, use FM mode
4. Select the antenna frequency to be used, use 20-30W power in FM mode, press the radio PPT, observe the ATU antenna tuner PWR and SWR
5. The use of ATU button TUNE: short press (less than 1 second) ATU button, it is in reset state, long press (more than 1 second) ATU button is in adjustment state
6. If the SWR display of the ATU antenna tuner is greater than 2.0 in the transmission state, it means that the antenna has been detuned. You need to use an antenna tuner. Press and hold the ATU button TUNE to tune and observe the SWR value. If the SWR is greater than 3.0 after tuning, the antenna will be detuned. Seriously, it is not recommended to use more than 30W power, and the transmission power should be controlled below 30W; if the tuning is completed, the SWR display is less than 2.0, and the maximum power of 100W can be used for transmission
