I wonder if anyone has ever tried, for want of a better name, a "Skeleton Cone" which consists of a single horizontal wire connected to the coax center conductor and two sloping wires at 45 degrees, in the same plane connected to the coax shield. A true Discone antenna would have many (typically eight each) horizontal and sloping elements. I'm guessing many of us have used the VHF/UHF version for very wide band coverage, for example 144, 220, 432 MHz and even higher. I know I have one up and it performs as well as a regular single band ¼λ ground plane (unity gain) on all three bands with low SWR. The ICOM version as well as a few others, also have a loaded whip for 52 MHz mounted on the bushing that the horizontal elements are screwed into.
I'm also guessing the formulas for a true Discone would work for a "skeleton" style as well. I Since it is inherently a wide band design, the actual lengths are probably not too critical. I've heard this type antenna described, but I don't remember where or how well it supposedly worked. It obviously requires two supports, high enough that the sloping wires ends are off the ground by a bit. 73, Charlie k3ICH ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
