Simple Ham Radio Antennas: A 3 Band Delta Loop. Post #290.

While I was looking for some loop antenna ideas to try out at my new QTH, I came across this article. Great video which contains numerous approaches to designing and building a multiband delta loop antenna. I will try a variation of this antenna for 40-10 meters using 450 ohm ladder line as the feed line. Aloha, Russ Roberts (KH6JRM).

Simple Ham Antennas: The Novice 40 meter delta loop. Post #271

During that brief period between getting my novice amateur radio license and moving on to the technician and general class license (1977-1983), I built several dipoles, inverted vees, and verticals.  All of these antennas worked very well, considering the lack of space I had at the time.  When my xyl and I moved from Honokaa to Laupahoehoe , we occupied a larger home and had more backyard space to place antennas. Just before I passed the Advanced Amateur License exam, I built what I considered my best and "most forgiving" antenna--a full-wavelength 40-meter loop.  The loop displayed some gain over a dipole at the same height, needed only one tall support, and didn't require a ground radial system to operate efficiently.  Using balanced feed line , a 4:1 current balun, and a Drake MN-4 transmatch, I could cover 40, 20, 15, and 10 meters with one antenna.  Later on, when 30 meters became available to amateur radio operators, I used a MFJ-941-E Versa Tuner II and my sp
