works great
would like to see this in a 12 volt version. I tried a 1.8-50Mhz Automatic Antenna Tuner, 10-15VDC 100W HY100 HAM Antenna Tuner, and it didn't work at all. I sent that one back and got this version that worked right out of the box The sellers store says "You need to use 9‑12V to start the ATU‑100. If you use a power bank or computer USB port to output power, you cannot start the ATU‑100 because their voltage is too low " There is no place to power it from 12 as it has a usb cable. I think there may be a mistake in translation and it should read watts not volts. The internal battery was enough to start it. Excellent

Works great on my 24 ft EFD antenna.
Works great with my FT 710. Only have a 24ft EFD antenna due to HOA. FT 710 ATU couldn’t tune that short antenna on 40 and 80 meters. The ATU -100 solved that issue. Good value.

PILE OF JUNK AUTOMATIC TUNER
Don't buy this product. I have read how it will burn out easy after I ordered it. So when it arrived it did not have very clear instructions. As a precaution, I took my radio and the new tuner to an authorized radio shop. He hooked it up and swr was 1.3 with the power output on radio set to 25 watts. Unit was in automatic mode and as soon as the mike was keyed, the display screen went blank. This is a true piece of junk, I'm serious, it will not work and you will have a box of junk for nothing. I would rate it myself as a -500
