ATU-100-0A 1.8-55MHz Mini Automatic Antenna Tuner 0.91inch OLED Display L5D3

Description

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 HF band of 1.8-30MHz. Built-in lithium , 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 stations. You can have a try.

button to on/off, easy to use very convenient.
Instructions:
Connect the , ATU antenna tuner and antenna.
For the first use, please set the output of the or amplifier between 20-30W, or the high- tuning can easily damage the antenna tuner.
Set the mode, use frequency modulation mode.
Choose the antenna band to use, use 20-30W in frequency modulation mode, press the 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 , it is not recommended to use more than 30W , and the transmission should be controlled below 30W; If the tuning is completed, the SWR display is less than 2.0, and the maximum of 100W can be used for transmission.
