As some of you have heard me hint for about a year, a revolution in small HF Antennas is unfolding at Applied Research Labs, Univ. of Tx. I have been an observer of experiments, sounding board, and k

That might indicate someone has a *very* large patio or a very poor calculator. Bandwidth is tied to energy storage in the system. When an antenna is physically small and efficient, energy storage i

I'm definitely going to get a copy of the article. Have you seen the "Super C" antenna that Gap is advertising on their website, www.gapantenna.com It sounds somewhat similar. Mark

Tom, I agree. And notice that all the NEC programs give antennas over ground 3 dB excess gain. They do this by presuming that the isotropic reference is located at coordinates 0,0,0 and half immersed

I went by the library after ham club meeting last night and made a copy of the folded conical helix antenna. I've not digested it yet. My initial impression of the illustrations is that it tries to m
