ATU‑100 Mini Automatic Antenna Tuner 0.96in Display Radio Automatic Antenna Tuner with USB Cable 1.8‑55Mhz Radio Tuner

How to Use:
1. Connect the radio, ATU antenna tuner, antenna
2. Set radio mode, use FM mode
3. Select the antenna frequency band to use, use 20‑30W power in FM mode, press radio PPT, observe the ATU antenna tuner PWR and SWR
4. 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
5. If the SWR of the ATU antenna tuner shows 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 tuned SWR is greater than 3.0, the antenna will be detuned. Special attention, it is not recommended to use power above 30W, and the transmit power should be controlled below 30W; if the tuning is completed, the SWR shows less than 2.0, and the maximum power of 100W can be used for transmission

Easy Operation: This automatic antenna tuner case requires no assembly and is developed by N7DDC for automatic tuning. Made of aluminum alloy material, light weight and corrosion resistance, has good heat dissipation effect. Mini automatic antenna tuner, with 0.96in organic light emitting diode display, support USB charging
Voltage And Frequency: The working voltage is 10‑15VDC, the working frequency range is 1.8‑55 MHz, and the application range is wide. Using excellent 1000V high voltage SMD capacitor, C channel capacitor, and advanced PIC chips
Note1: When using for the first time, please set the output power of the radio or power amplifier between 20‑30W, warning that high power tuning may easily damage the antenna tuner
Note2: Insufficient adjustment may occur within 5W, so do not lower than 5W. It is recommended that the maximum power should not exceed 30W during tuning. (It can be set to 100W after tuning, and work at this power, otherwise it is easy to burn)
Note3: You need to use 9‑12V to start the ATU‑100. If you use a power bank or computer USB port to output power, you cannot start the ATU‑100 because their voltage is too low
