ATU-100 EXT Antenna Tuner 1.8-50MHz atu100 by N7DDC 7x7 0.96 Inch OLED 3.2 Firmware Programmed with Housing Assembled Machine with USB CableNo Battery Compatible with Radio Antenna

The latest program version 3.2 has been installed. Compared to version 3.1, several bugs have been resolved. This is an automatic antenna tuner with a housing (battery not included). No assembly is needed; it is ready for immediate use. It features automatic tuning technology developed by N7DDC and is compatible with radio antennas. It contains premium SMD capacitors, C-channel capacitors, high-voltage 1000V SMD capacitors, an imported PIC chip, and a genuine UHF connector. The housing is compact and elegantly designed. The entire housing, including the front and rear panels, is constructed from aluminum alloy, not PCB material.

You will receive: the ATU-100 automatic antenna tuner with housing (no battery), one DC 5.5 x 2.1 power cord, and one USB booster board. This board (5V boosted to 12V) is connected to the USB cable, and the 5.5 connector power cable is pre-soldered to the booster board. It can be powered by a portable power bank (typically not required under normal conditions). Do not attempt to operate below 5W, as insufficient tuning may occur within the 5W range
