Roy, I remember it well. You plonked me when I
reminded you that an antenna is a distributed
network and NOT a lumped circuit. Anyone can
verify that simply by googling the newsgroup.

I have no other choice but to repeat the questions
that you, so far, have refused to answer.

So here is it again: How can one use the total
current in a 1/4WL monopole, which changes phase
by 3 degrees in 90 degrees of antenna, to measure
the delay through a wire or a loading coil?

It's a really simple question, Jim. Either one
can or one cannot.

Beeep. Check Google newsgroups, yesterday at 7:11 PM.

Beeep. Check this very newsgroup. I already responded
to that posting. You didn't answer the question. We
are not talking about discontinuities. We are talking
about a straight 1/4WL piece of wire. So allow me to
keep asking until I get a reasonable response:

EZNEC says there is ~3 degrees of phase change in the
current in 90 degrees of monopole. How can that current
be used to measure the delay through 'n' degrees of
monopole?

For instance - in 30 degrees of monopole, the current
shifts phase by one degree. What *exactly* does that
indicate? Wouldn't the delay be more accurately
measured by comparing the ARCCOSine of the amplitudes?

OK, Richard, I admit that you caught me asking rhetorical
questions - Congratulations!

Richard,

If it doesn't come through on an initial read, I have tried to deconstruct
the fig a) / Fig 1 configuration, and then synthesise it with another
structure with and without the common mode current path, and observe the
effect on current distribution... then compare that with the TL
representation.

If the development isn't clear, I have some more work to do!

....
I will have to revisit the comments in this thread and tie them to the
cogent points of your page.

Constructive comments are always welcome, and appreciated.

Thanks
Owen

Hi Jim,

You have experienced the famous time conjugated
answer-preceding-the-question paradox of Cecil's information
transformation. What Cecil is saying (we are now employing the random
byte discard from the data babblefield):
you have misunderstood your answer to the question I am asking now.

Hi Owen,

This is a lot to digest at this time, but at least it is all in one
place and done well.

You offer several many solutions (to what are arguably straw men
hypothesis such as the W5GI mystery antenna) and there are certainly
gaps that beg filling: Fig. 2 is rather anemic as is the original
supporting commentary.

I offered a comment long ago that my best guess was that phasing would
seem to separate your two examples. That seems to have been both
vindicated and rejected through the numerous examples - I've lost
track of the focus.

I will have to revisit the comments in this thread and tie them to the
cogent points of your page.

I have absolutely no idea. Sounds like you've made an error somewhere.
