Does reactance of dipole depend on diameter ??

As someone else said, this stuff can get very complex very quickly. Hi Dave, Your kick-off was already complex. A thick-wire can be monstrously thick and not do much about the overall length at the principle resonance: http://home.comcast.net/~kb7qhc/ante.../Cage/cage.htm It does have its advantages higher in frequency. When we look at cage conicals, the flare angle of the conical shows interesting relationships - not so much at resonance as for the continuum of reactance and resistance. What I describe as optimal bears upon an arbitrary 50 Ohm relationship, but others might mine significance from the steeper skirts of the discone. http://www.qsl.net/kb7qhc/antenna/Discone/discone.htm 73's Richard Clark, KB7QHC |
