My dual-trace scope measurements agreed within
the accuracy to which I could measure.

Point is that the delay through a transmission
line, a wire, or a coil is the same no matter
what type of current (standing wave or traveling
wave) is flowing. EM waves are EM waves. If the
current is primarily standing wave current with
essentially unchanging phase, the phase shift
in the standing wave current is unrelated to the
delay through the T-line, wire, or coil. Yet
standing wave current phase is what was used to
"prove" a 3 nS delay through a 100T, 2" dia, 10TPI
coil on 75m. If traveling wave current had been
used, as I did on my 75m Texas Bugcatcher coil,
the delay would have been shown to be ~26 nS.

In a 1/4WL monopole or 1/2WL dipole, the total
current is about 90% standing wave current.

Did you take a look at the current phase in these
two inverted-Vs?

Exactly why I plonked him a few years ago. The relative silence is
refreshing, and I haven't missed a thing.

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.

On my end, it's like trying to communicate with
an I/O interface that is all output and no input.
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.

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.

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

Congratulations? In noting the absolute uniform homogeneity for the
technical equivalent of:
"Are we there yet?"

Cheap kudos with the equivalent buying power of shares in Lehman
Brothers.
"Are we solvent yet?"

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?
