Default Current across the antenna loading coil - from scratch

You really think so, Cecil?? I saw through it the first time you
posted it. As an EZNEC and NEC2 user, I know that not only the current
magnitude, but also its phase, is reported. I knew that what you
posted about it was incorrect. I don't see Roy's comment as agreeing
with you at all, but completely disagreeing. You said that it only
gave amplitude information, when in fact it gives phase and amplitude.


Again, no quote from me. I have no idea to what you are responding
or even if you are responding to something I said today or last year.

I didn't say EZNEC doesn't give phase information. I said there is
no phase information in the phase information that EXNEC gives.
What is it about Gene's posting that you don't understand?

Regarding the cos(kz)*cos(wt) term in a standing wave:

Gene Fuller, W4SZ wrote:
In a standing wave antenna problem, such as the one you describe, there is no
remaining phase information. Any specific phase characteristics of the traveling
waves died out when the startup transients died out.

Phase is gone. Kaput. Vanished. Cannot be recovered. Never to be seen again.

The only "phase" remaining is the cos (kz) term, which is really an amplitude
description, not a phase.
