If you use a long or random length wire for your home or portable antenna, a good ground radial system, an antenna "tuner", and a sturdy 9:1 balun are necessary to keep SWR low and RFI out of your shack.
In this video, "Tinker John" (W5CYF) shows us an easy, simple, and inexpensive way to build a 9:1 balun for any random length wire antenna you use. John takes us step-by-step through the design, construction, and use segments of this handy, "one-evening project." Make two of these baluns--one for home use and the other for your mobile "go-kit."
