Simple Ham Radio Antennas. A 5-band vertical dipole. Post #286

How would you like to have a 5-band vertical antenna that covers 20, 17, 15, 12, and 10 meters that requires no ground radial system and can be built from materials from your junk box or from the nearest hardware store? You can, if you build a simple Vertical Dipole and feed it with 300 ohm television twin lead or 450 ohm ladder line terminated into a balanced antenna "tuner." If your "tuner" has no provision for balanced feeders, you can insert the twin lead/ladder lead into a 4:1 current balun and use a short piece of 50 ohm coaxial cable to connect the antenna to your "tuner." I got this idea from an article in "Simple and Fun Antennas for Hams" by Chuck Hutchinson (K8CH) and Dean Straw (N6BV).  Hutchinson and Straw conducted a series of antenna experiments using 15 meter vertical dipoles in a space-restricted urban area. The results of their work were impressive, so I decided to use some of their suggestions and make my own version of
