A while ago I built myself a delta loop for 50MHz much like the one documented by GW7AAV. I've only tested it once and the SWR was very high. Today I decided to do another test and brought the antenna and my MFJ-259b Antenna Analyzer on a short hike into the woods. The measurements show that the antenna is just a little to short and has a SWR at 1.5 : 1 at 50.150MHz. I didn't bring the Yaesu FT-817ND but will test some qsos one of these days.
