It is now on my little roof tower in "inverted vee" configuration. http://en.wikipedia.org/wiki/Inverted_vee_antenna. This one works on 7-28 MHz as an inverted vee, and also on 3.5 MHz with the feedline shorted together so it works as a short vertical with a capacitive top hat. Each leg is 82 feet long. To paraphrase Abraham Lincoln, each leg is long enough to not quite reach the ground. It's fed with 300 ohm twin lead rather than coaxial cable, so with a manual tuner, I can resonate the system to many bands. --Peter (aka KD7MW) > My favorite antenna.
