I finally got around to putting a mag loop together tonite. Using 10 ft of 5/8′ copper tubing I made a circle and using some lath strips I had laying around I made a lightweight frame. (too light) I had a nice pair of air variable caps mounted in parallel and made an exciter loop for testing out of #12 solid copper wire. Using a BNC to binding post adapter I hooked it up to my MFJ 207 antenna analyzer. It is showing 2:1 SWR on 7.040 and I think with a bit more capacitance I can bring it down. It is too late to do much more tweaking tonight, but I’ll update you on progress and other experiments. Here’s a quick look at it as it is now in its testing mode.
