That point seems difficult for you to fathom.
They are related in a traveling-wave environment. They are
virtually unrelated in a standing-wave environment. W8JI
asserts that the delay through a 100T coil at 4 MHz is
3 ns which is impossible. If he had asserted that the
standing-wave current undergoes a 4.5 degree phase shift
through that coil, we wouldn't be having this argument
because the phase of standing-wave current is virtually
constant over the length of a 1/2WL dipole. At the ends
of a dipole longer than 1/2WL, it does an abrupt 180 degree
phase shift. W8JI and W7EL seem to be totally ignorant of
that fact of physics since they both tried to use standing-
wave current to "measure" phase-shift/delay.
Cecil,
As usual you clipped out the interesting part of the message.
By the way, saying something is "impossible" is religion, not science.
The distance from one end of the coil to the other is clearly within
reach without violating the speed of light.
