Wire diameter vs Impedance - correction

So, if Length / Dia equals e / 4 (about .67957), then C = infinite? ==================================== C even goes negative for smaller values of Length/Dia. I'll let you into a secret - the formulae are approximate and don't apply when antenna length is less than about 5 times its diameter. When was the last time you saw an antenna wire only 5 times longer than its diameter? You should supply your "secrets" along with your formulae. |
