This is an update of a previous video I made about the ATU-100 antenna tuner using my Bearcat 980 SSB. The first half of the video is the same that explains the tuner. I decided to try the tuner on a mag mount car antenna mounted on a cookie sheet to demonstrate the ATU-100's abilities of lowering SWR. Feel free to fast forward to the test if you have watched the first half before. Here's the link to the instructions that came with the ATU-100 EXT tuner: https://drive.google.com/file/d/1AulO...
