1. [Antenna tuner + standing wave meter 2 in 1] Antenna tuner, power, standing wave meter, supports display of standing wave value, forward power, and reverse power. In the non-tuned state, the power meter mode supports a maximum display of 150W SSB/CW. 2. [Powerful tuning capability] Built-in super-large capacitance and inductance value combination greatly improves the tuning success rate and reduces the trouble of repeatedly adjusting the antenna feed system. The maximum combination value of capacitance is up to 3869pF, and the maximum combination value of inductance is up to 17.21uH. 3. [Built-in multiple professional settings] The system supports 13 advanced parameter configurations, suitable for high-level players to deeply customize, such as automatic storage quantity, tuning speed, start-up power, start-up standing wave, power calibration, standing wave calibration, signal test, relay test and other functions, customize your antenna tuning system 4. [Six status interfaces, freely selectable] The system supports 6 status interfaces, including user storage interface, bar power standing wave table interface, large font interface, standing wave curve interface, power curve interface, relay and battery voltage status interface 5.[Manual tuning and automatic tuning] Supports both manual tuning and automatic tuning. In automatic mode, when the standing wave exceeds the set value (default 1.80) when monitoring the radio station transmitting the signal, it automatically trigger the tuning of the lowest standing wave. Supported radio stations: Support most radio stations and antennas on the market Automatic memory channels: 60 groups Maximum combined inductance value: 17.21uH Maximum combined capacitance value: 3869pF Standing wave meter: Support Power meter: Support (0.1W-150W) Interactive mode: Bar mode,large font mode, relay mode, power curve mode, standing wave curve mode, CW exerciser mode, configuration menu mode Automatic tuning mode: Support Manual tuning mode: Support (inductance or capacitance value can be modified arbitrarily for manual tuning) CW practice: Support external 3.5mm headphone jack single-paddle CW practice Support front panel button trigger practice Buzzer: Support (automatic prompt when exceeding the set standing wave) Battery capacity: 3300mAh Charging interface: USB-TYPE C Charging time: about 4 hours Product power consumption: maximum 5W Standby time: About 150~200 hours (no tuning action) Tuning time: about 10~25 hours (starting 1-3 relays) Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.
