and there is  some striking revelation about Zenneck Wave in the picture below.
Yes it is striking.
Think about coverage  of entire earth.

Zenneck wave is a well-known science.
His teacher was Sommerfled who was the originator of eigenmode theory in waveguide. So far there has not been anyone capable of disproving  any of Sommerfled's theories.

James Corum has done a great job in proving the existence of Zenneck wave. He is also a IEEE member.

Hi SolarLab,

I didn't have any problem with the duplication after having realized that the cable ends must be sort-circuited, not open.
One end is connected to the FG via a coaxial T-shaped connector with a short-circuited middle input. However, my jumpers have a slight impedance so that a small part of the signal passes through and is reflected back and forth many times. For the same reason the scope probes at each end pick up the signal on the jumpers.
 
The first picture shows the comings and goings of a 16ns pulse repeated at a low rate of 797KHz so that we have time to see the reflections in the time of each period.
We can see that the attenuation at -3dB allows more than ten round trips of the pulse, which indicates low losses.

The second image is the signal of the 5 superimposed sine waves generated by the FG, at a frequency of 15.94 MHz for the lowest (the others are multiple).

The last image is the signals probed at the ends of the cable, FG side for the yellow trace, and the other for the purple trace.

The time between the maximum of one trace and the minimum of the other corresponds to the travel time of 30 ns in my 6 m line, velocity coefficient 0.66c.

This is the temporal signal while Gorchilin's animation showed the spatial representation, so it is necessary to do some mental gymnastics to understand that the two correspond, except that the amplitudes of the positive and negative oscillations are not exactly balanced, I don't know why.
Don't trust the volt level of the traces, I had a problem with a probe and the impedance multipliers of the probe are not declared correctly in the scope (but this is not related to the positive/negative imbalance).

In any case, a standing wave is always the superposition of at least two progressive waves which propagate in opposite directions. Progressive waves are always "hidden" in standing waves, so for me the Gorchilin's configuration is just a phase arrangement, it doesn't bring anything new. Spatially the energy is still static.
