Simple Ham Radio Antennas: A Multiband Loop Antenna, 80 meters through 10 meters. Post #326.

An excellent video guide to building, erecting, and maintaining a simple 80-10 meter loop antenna . Lynn (NG9D) covers the basics in a short, well-produced video that can be applied to many home situations. With careful attention to detail and choice of wire, the antenna is fairly stealthy--something of concern to many of us "penned in" by neighbors and nearby buildings. Lynn uses commonly available RG-58 and RG-59 for the feedline. If you can't find two tall supports, try designing the antenna as a delta loop. A tall tree limb or a telescoping fiberglass mast could serve as the apex of the loop. If space is a concern, you could build the loop for 40-10 meter coverage. If you're worried about high SWR on the coax, feed the loop in a bottom corner with 450-ohm ladder line . Run the ladder line to a balanced antenna tuner or to a 4:1 balun. Fifty-ohm coax would then run from the balun to your antenna transmatch (tuner) and onto your rig. Either way, the
