Art -
In your perception you have merged my r-f pulse measurement link with
my link to a relevant I.R.E. paper by Gihring & Brown of RCA.

But while both of these links show the existence of reflections, they
can not be combined in any manner to reach the conclusion stated in
your post clip quoted above.

Regardless of that, you continued your post with...

For a fractional wave antenna skin depth or resistance on the surface
does not disappear until the trailing edge of the RF pulse reaches the
antenna top. In the mean time current rises at the top as the fields
collapse which means that the lead current is prevented from turning
around because skin resistance is still being maintained. Thus it has
no other choice to pursue a closed circuit other than travel on thenside
of the radiator and being shielded by the surface eddy currents
produced by the trailing current end. etc

Art, consider just the Gihring/Brown measurements linked to earlier in
this thread. They were made using a continuous, non-pulsed r-f
waveform, so none of your beliefs posted above will apply.

Yet the current distribution measured along the lengths of those
radiators by Gihring/Brown proves the existence of reflections from
the end of such radiators, and that such reflected r-f current does
not return from the end of such radiators via a non-radiating path
through the center of the same conductor, as you suppose.

I will not add to this thread as it is surround by closed minds of the aged.

But not for the reason you state next above, I'd wager.
