Comment: If you're forced to use one HF antenna for your Amateur Radio activities, you may want to consider this simple, effective multi-band loop antenna from Rik van Riel (AB1KW). According to Rik, this loop will permit operation on all Amateur Radio bands from 80 meters to 10 meters.  The antenna uses 86 meters (approximately 242 feet of wire for the multiband loop), which is bit small for 80, 17, and 12 meters, a tad large for 40 and 30 meters, and just right for 20, 15, and 10 meters.  An antenna transmatch  (i.e. "tuner") can compensate for some of the length measurements. Rik does an excellent job of discussing all aspects of designing a resonant hf loop antenna, examining the gain and radiation pat
