But you're doing all the talking, Cecil - providing profound and
knowledgeable insights as in the above observation that phase shift and
delay are unrelated.


I guess I should provide a context for the uninitiated.

If the system contains only traveling waves, the delay
is proportional to the phase shift. If the system contains
only standing waves, the delay is completely unrelated to
the phase shift since the phase shift is always zero over
any 1/2WL between the current nodes. EZNEC supports that
fact and w7el has admitted such in a previous posting.

Kraus and Balanis both agree with the above assertion. I
believe that you are aware of that fact so I have no choice
but to assume that you are deliberately trying to hoodwink
the uninitiated as are w7el and w8ji. Your ulterior motives
remain unclear to me since you will not doubt be proven
technically wrong at some point. You guys cannot possibly
plead ignorance after all these years of discussion.

Traveling wave current changes phase relative to the source
current. Every technical person agrees on that fact of physics.

Standing wave current does not change phase relative to
the source current. Everyone technical person agrees on
that fact of physics.

Therefore, standing wave current phase cannot be used to
measure delay through a wire or through a coil. This is
such a simple concept that any disagreement must be
considered to be a conspiracy to hoodwink the uninitiated.
Exactly what do you guys have to gain from hoodwinking
the unwashed masses???
