Inaccurate; I take it back.

Yes, if you look at the applet in here, the end-fed antenna and center-fed antenna have different current distributions. Then the radiation resistance will change :mad:, now I have to rewrite the current distribution equation (no longer sinusoidal). Doesn't look like a trivial task! I am...

Nice, so this confirms the radiation impedance part. Problem is my analytical solution is not matching the simulation. I'll play with it and see if I can get them to match.

The V/I ratio is definitely different at different points giving us different input impedances. As for the radiation impedance, it seems to me that it's analogous to the characteristic impedance of a transmission line which is geometry specific. I might be mistaken.

Hi, I'm trying to find the input impedance of an OCF dipole and I need a sanity check by one of the more experienced guys here. Now, I have assumed that the voltage and current distribution along the line is always the same, no matter where you feed the antenna at [1]. The radiation resistance...
