1. This antenna tuner Compatible with most radios and antennas on the market, such as for , ICOM, , , USDX, QRP, and more. Supports end-fed, vertical, horizontal, , inverted V, car-mounted antennas, and more. The system supports 6 different interface modes, including user-defined interface, bar graph SWR meter interface, large font interface, SWR curve interface, power curve interface, relay, and battery voltage status interface. 2. This automatic antenna tuner functions as an antenna tuner and also displays power and SWR values. It can display forward power, reverse power, and SWR values. In the untuned state, the power meter mode supports a maximum display of 150W SSB/CW. Please calibrate the SWR power value of this device when using it for the first time or when changing radios. 3. This shortwave antenna tuner built-in large capacitors and inductor combinations greatly improve tuning success rate and reduce hassle of repeatedly adjusting feeder system.maximum capacitance combination value is up to 3869pF,and the maximum inductance combination value is up to 17.21uH.Supports both manual and automatic tuning modes.In auto mode,when SWR exceeds set value(default 1.80)while monitoring transmitted signal from the radio,it automatically trigger the lowest SWR tuning. 4. The rear panel of this standing wave meter features a 3.5mm headphone jack that supports external single-paddle keys, allowing you to easily practice Morse code in your . 5. The system supports 13 advanced parameter configurations. Functions include auto storage quantity, tuning speed, starting power, starting SWR, power calibration, SWR calibration, signal testing, relay testing, and more. Customize your antenna tuning system.
