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 Cable(No Battery) Compatible with Radio Antenna

The latest program version 3.2 is installed. Compared to version 3.1, several issues 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 incorporates automatic tuning technology and is compatible with radio antennas. It uses premium SMD capacitors, C-channel capacitors, high-quality 1000V high-voltage SMD capacitors, and an imported PIC chip. It features a genuine UHF connector. The housing is compact and elegantly designed. The entire enclosure, including the front and rear panels, is constructed from aluminum alloy, not PCB material. The package contains the ATU-100 automatic antenna tuner with housing (no battery), one DC5.5 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 soldered to it. It can be powered by a portable power bank (typically not necessary). Do not operate below 5W. Insufficient tuning may happen within the 5W range
