Review on SDRGEEK 1 8 55MHz Automatic Shortwave Assembled by Shane Jenkins

ATU-100 will not fit my 71 foot cables, 9:1 single antenna. With the MFJ-904 manual tuner I can tune the same antenna to a 1:1 SWR on all bands, 80-10 meters. I tried two ATU-100's, one from Revain and one from another vendor. Both had the same problem. I returned an ATU-100 purchased from Revain and received an immediate full refund which is why I'm giving Revain's customer service two stars instead of one. You may have better experiences using the ATU-100 with a different type of antenna, but I wouldn't buy an ATU-100 for a 9:1 single feed antenna.
