Default Current across the antenna loading coil - from scratch

Awww, MAN,Cecil. I am sorry. I had no idea that you were putting up
with a newsreader that can't follow threads, and in addition you have
such a severe short term memory loss that you can't follow what's been
posted within the past couple hours.

Bummer, man. Real bummer. I feel for you. It's a really bad
combination.

We should be able to help you out with the newsreader problem if you
want. I'm not so sure about the memory loss thing, though. It might
help if you didn't try to keep so many balls in the air all at once,
but I don't know that for certain.

I've patched together below (from the newsreader I use, which does keep
track of all the branches of threads) what I wrote and what I was
replying to in this particular sub-thread, so you can see it all in one
place. If you'd like, I could do the same with the postings from other
sub-threads here and from that other thread-that-wouldn't-die and email
it to you, but that would be on a time-permitting basis.

Cheers,
Tom

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.

I see that Cecil's latest fetish is that EZNEC reports RMS values of
voltage and current. Because we know that the voltages and currents are
purely sinusoidal, the RMS value and phase angle (also reported by
EZNEC) are adequate to define the time waveform. That is, when we know
the RMS amplitude and the phase angle, we know the value of the waveform
at every instant in time. No additional information is necessary.


Since you agree with me, what's with the fetish remark?
You seem to feel obliged to take an ad hominem pot shot
every time you mention my name. I assure you, it is
hurting your reputation more than it is hurting mine.

By implication, this is also with respect to what Cecil wrote at the
end of another subthread. The in-reply-to-s can be used to trace
things back...:

I beg your pardon? Excuse me? I "trimmed out all the technical
content and didn't quote anything you said"???


Yes, and you are doing it again. I'm quoting your entire posting
and there is not one quote from me.

As a matter of fact, I
took exactly the numbers you gave us, ALL of them, and used them and
ONLY them in my accounting. If THAT's "disembodied from reality," then
I'd point out that it's YOUR numbers that are disembodied from reality.
In fact, I didn't argue with YOUR numbers at all. I just took them at
face value. You were the one that discarded what I carefully developed
from them without out so much as an ounce of reasoning or explanation.
After that I went on to FURTHER EXPLAIN why I had done what I did in
the first place, and you dismissed that again without any technical
explanation.

It's all there for everyone to see, Cecil.


If there's a quote from me in this posting, Tom, I am unable
to find it.

Go ahead, dig yourself deeper into it.


Since you didn't quote anything I said, I have no idea what
you are talking about.
