ATU-100 EXT Antenna Tuner for Ham Radio, GOOZEEZOO V3.2 1.8-55MHz Automatic Antenna Tuner by N7DDC 100W Open Source Shortwave Antenna Tuner with 5000mAh Battery
ATU-100 Automatic Antenna Tuner: The equipment is intended to be used as an accessory of amateur radio equipment, as part of amplifier or transceiver, or as a separate equipment, to realize the function of matching the output impedance of power amplifier (PA) with antenna feeder.
【5000mAh Battery】 This product contains 5000mAh rechargeable batteries. The power input port can be connected to the DC 12V power supply, which is positive inside and negative outside (note: this device contains 15V TVS limiting diode for power supply protection, and the fuse will be blown when the DC power supply voltage exceeds 15V). Before charging, please confirm that the output voltage of the battery charger is less than 5V (the battery charger is not included).
【Tuning Range】 Voltage: 10-14.5V DC; Minimum power required to start tuning: 5W; Maximum current consumption: 400mA; Minimum measured power: 0.1W; Maximum working power: 100W; Measurement step of power up to 10 watt hours: 0.1W; Maximum measured power: 150W; Measurement steps for power higher than 10 W: 1W
【Easy to Use】The hf antenna tuner no need to assemnble and you can use it diretly. This equipment is intended to be used as an accessory of amateur radio equipment, as part of amplifier or transceiver, or as a separate equipment, to realize the function of matching the output impedance of power amplifier (PA) with antenna feeder.
【Compact and Portable】The dimension of qrp antenna tuner is 9*5.1*2.4 inch. The small size allows you to carry fewer devices and bring more superior connectivity experience. 0.91-inch OLED dual-color display screen is adopted, and the parameters are displayed in four lines: the first line shows the input power value;
The second line: display the voltage standing wave ratio; The third and fourth lines display L and C parameter values or antenna output power, efficiency or other key operation status.
【Quick to Set up】 Starting Power: in the Manual Mode, the input power of the equipment must reach a certain threshold to trigger automatic impedance adjustment, which is the starting power value. Power Supply: the switch has three levels: Upper: use the power supply line to connect to the DC12V port of the rear panel for power supply. Medium: Turn off the power. Lower: Use internal battery for power supply. (At this time, the battery indicator light is blue, and it is red when charging).
Press and hold the RESET/TUNE key, and the word TUNE will appear on the screen. At this time, the continuous power adjustment of the transmitter can be automatically adjusted. Press the RESET/TUNE button for a short time, and the ATU-100 releases the previously adjusted LC relay and is in the straight through position.
