Did they mention where an actual drawing can be found
or if an indepth descriptive article can be found? Thanks Art What I described, says it all. The variation from the helically wound coil at the bottom half of the radiator is the trombone like "coil" or loading stubs. Looks like one or two turn trombone loading stubs along the radiator. This should model in EZnec and show how the current decreases. Not much different from the loading coil at the base, which any mobile aficionado knows is the worst place to put the loading coil at. Again. It is vertical, working against radials, or screen, loaded at the base with helical coil or trombone, then piece of tubing, then loading coil, than piece of tubing (stinger) or top hat. You can play with any sizes you like, it will not beat "classic" whip with loading coil about 2/3 up the radiator. When the patent is issued and published, you will be able to see where the "secret" is. He promised to have something on the web site, but I did not bother to take a note of it. 73 Yuri, K3BU.us www.computeradio.us home of Dream Radio One |
