Cheap Skyloop Antenna

This is post 2222 in a continuing series of simple ham radio antennas. One of my favorite multi-band HF antennas is the full-wavelength loop. Properly designed, supported at a decent height, and fed by a balanced feedline/4:1 balun combination into a wide-range antenna "tuner", this antenna will give you many hours a enjoyable contacts. Callum (M0MCX) does an excellent job of covering all the basics and adjustments needed for this HF antenna. Here are some of his observations: "Years ago, we ran a huge triangular loop at the Scout Hut in Dorridge. This was fed with coax and a 4:1 balun to bring impedance to near 50 ohms. I discuss the problem in matching the harmonics related to 80m and 40m and also the slightly higher SWR on 160m due to the loop (in percentage terms) being low to the ground. All the other bands were fine.
