Description
The shortwave automatic antenna tuner contains a set of 7 capacitors and 7 inductors, allowing it (with the largest configuration) to work effectively in a wide frequency band, overlapping the HF band 1.8-30MHz amateur radio. Built-in lithium battery, 3.7V, 1800mAh, you can use Type-C cable to recharge it. Equipped with a 0.91-inch OLED screen, you can see the data clearly. Automatically tuned and no control cables needed, suitable for most radio stations.
Features:
The shortwave automatic antenna tuner contains a set of 7 capacitors and 7 inductors, allowing it (with the largest configuration) to work effectively over a wide frequency band, overlapping to the amateur radio HF band of 1.8-30 MHz.
Made of quality material, wear resistance, with stable and reliable performance.
Built-in lithium battery, 3.7V, 1800mAh, you can use a Type-C cable to recharge it.
Equipped with 0.91 inch OLED screen, you can see the data clearly.
Automatically tuned, no human or control cables required, and suitable for most radio stations.
One button to turn on/off, easy to use and very practical.
Instructions:
Connect the radio, ATU antenna tuner and antenna.
For the first use, please adjust the output power of the radio or power amplifier between 20-30W, or high power tuning can easily damage the antenna tuner.
Set the radio mode, Use the 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 the antenna tuner
ATU. Using ATU TUNE button: 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 the antenna is detuned.6. You need to use an antenna tuner. Press and hold the ATU tune button to tune and observe the SWR value. If the SWR is greater than 3.0 after tuning, the antenna will be detuned. In severe cases, it is not recommended to use more than 30W power, and the transmit 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.
