Ouch, leave it to be the one time I'm in a hurry and don't proofread my text is when I screw up. Change those two times I typed "radiation resistance" to "impedance".
By the way, where did the 50 ohms come from, I never said that specific impedance had anything to do with resonance, not once, ever. As a matter of fact I listed three possibilities (none of them 50 ohms and they were randomely chosen but possible depending on the antenna), and I included the text: I have specifically gone out of my way to not imply a 50 ohm impedance is in any way shape or form connected to resonance, and have never once made the claim. I said that earlier in this very thread as well as several others. ANY association with 50 ohms of impedance, resonance, and myself is in error. You have seen plenty of my posts in the past doc, you should know me better then this by now.
I merely stated that a resonant frequency (and for that matter near resonant frequencies can as well, although I did not include that) of an antenna presents a lower impedance then a nonresonant frequency. That is all. I never once said that an antenna could not have more than one resonant frequency. I never once said that different resonant frequencies would have the same impedance. I never said that different ways of feeding a resonant antenna length would have the same impedance. Please, if I ever made any of these claims find it and quote it to me.
What did I suddenly become a politician or something? If I did I hope it pays better then my current job... Maybe I can vote myself a raise or something...
So lets take the largest resonant impedance listed, the end fed half wave antenna can have 1000+ ohms of impedance, so what is the impedance if the resonant frequency of the antenna is 3Mhz off of the frequency you are using? I'll let you guys figure it out from here...
Edited the previous post to say what I meant to say in the first place.
