For those of you who have some space in your backyard, a random loop antenna can offer some interesting possibilities. When I was upgrading my new home in the Puna District of Hawaii Island a few years ago, I erected a 540-ft/164.53 meters horizontal loop on my property's spacious backyard, thanks to some 30-ft/9.146 meters Norfolk Pine Trees around the lot. The antenna generally followed the guidelines outlined in this video from Stan Gibilisco (W1GV).
The key components of this experimental antenna were a balanced "tuner" (or a 4:1 balun/"tuner" combination), balanced feed line, and a good ground system for your station. In my case, I used some speaker wire left over from a radio station news room renovation (I was working as a news announcer at the time for KHLO-AM 850/KKBG-FM (97.9 MHz), a roll of 300-ohm television twin lead, a 4:1 current balun, and my trusty Drake MN-4 antenna transmatch (i.e. "tuner").
Performance on the 80, 40, 20, 15, and 10 meter amateur radio bands was excellent, especially on local nets where low-level loops become good NVIS antennas.
If you follow Stan's guidelines, you can design, build, and use a random loop antenna with minimum expense and maximum pleasure. If you do a lot of local or regional HF contacts, this antenna can deliver solid performance at a modest investment of time and effort.
