Greetings, I just built a Moxon antenna for 6 meters with aluminum tubing. It was 2.2 SWR right at the start and after a little adjustment I got it down to 1.3:1 from 50 to 50. 200 And since that's where I operate In frequency I'm pretty happy with the SWR. Unfortunately My sinuses started getting the best of me so I had to quit messing with it for the day. Good SWR however when I checked it the next day I noticed It was about 43 ohms. I believe I know the answer but should I do more adjustment to get closer to 50 ohms or just be happy where it's at? Thanks, 73!
