Item Type:Antenna Tuner DIY Kits Material: PCBPurpose: Antenna TunerModel: ATU-100Maximum Current Consumption: 400mANumber of Installed Inductors: 7Number of Installed Capacitors: 7Power Measurement Step of 10 Watts: 0.1 wattsMeasurement Steps with Power Hiher than 10: 1 wattPower Measurement Accuracy: 10%Maximum Installation Inductance: 8.53uhMinimum Installation Inductance: 0.05uhMaximum Installed Capacity: 1869pfMinimum Installed Capacity: 10pfUsae Scenario: The device is intended to be used in the components of amateur radio equipment, as a part of an amplifier or transceiver, or as a separate device that performs the function of matchin the output impedance of a power amplifier (PA) with the antenna feeder. This device and the similar 2x5 roup The relay is different, which allows it (with the maximum confiuration) to work effectively in a wide frequency band, overlappin the radio amateur HF band from 1.8MHz to 50MHz.1Automatic Tunin: The antenna tuner adopts automatic tunin, the ATU (Automatic Antenna Tuner) KIT independently developed by N7DDC, equipped with an OLED screen, and the data is clearly visible. 2Hih Quality Capacitors: The antenna tuner uses hih quality brand chip capacitors, C channel capacitors, 1000V hih voltae chip capacitors, and imported PIC chips. 3Radio Amateur Frequency Band: The antenna tuner can work effectively in the broadband overlappin radio amateur HF frequency band from 1.8mhz to 50MHz. The maximum current consumption is 400mA, 7 inductance and 7 capacitance. 4Easy to Carry: This is a portable antenna tuner, so you can take with you wherever you want to use. 5Interestin Install: The easy to install antenna tuner allows you to enjoy the fun of assembly, and is more professional, more stable and better in performance.There are many parts, please be careful and patient when assemblin.1 x PCB Board1 x Connection Line1 x IC2 x Plu15 x Relay 6 x Capacitance6 x Porcelain Rin1 x Coil1 x Transistor 1 x Diode2 x Connector2 x Copper Wire1 x User Manual
