The shortwave automatic antenna tuner contains a set of 7 capacitors and 7 inductors, which allows it (with the largest configuration) to work effectively in a wide frequency band, overlapping the amateur radio HF band of 1.8-30MHz. Built-in lithium battery, 3.7V, 1800mAh, you can use Type-C cable to recharge it. Equipped with 0.91inch OLED display, you can see the data clearly. Automatically tuned and do not need control wires, suitable for most radio stations. You can have a try.

The shortwave automatic antenna tuner contains a set of 7 capacitors and 7 inductors, which allows it (with the largest configuration) to work effectively in a wide frequency band, overlapping the amateur radio HF band of 1.8-30MHz.
Made of quality material, wear resistance, with stable and reliable performance.
Built-in lithium battery, 3.7V, 1800mAh, you can use Type-C cable to recharge it.
Equipped with 0.91inch OLED display, you can see the data clearly.
Automatically tuned, no human and control wires are required, and it is suitable for most radio stations.
One button to on/off, easy to use very convenient.
Instructions:
Connect the radio, ATU antenna tuner and antenna.
For the first use, please set the output power of the radio or power amplifier between 20-30W, or the high-power tuning can easily damage the antenna tuner.
Set the radio mode, use frequency modulation mode.
Choose the antenna band to use, use 20-30W power in frequency modulation mode, press the radio PTT, observe the PWR and SWR of ATU antenna tuner.
ATU button TUNE use: short press (less than 1 second) ATU button, it is in reset state, long press (more than 1 second) ATU button is in tuning state.
If the SWR display of the ATU antenna tuner in the transmitting state is ＞2.0, it means that the antenna is detuned.6.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. In serious cases, 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.
