Plus they need to be linked to reality. Standing waves existing
without the component forward and reverse traveling waves is
divorced from reality. Neither you nor anyone else has been able
to provide even one real-world example of such.

Forward traveling wave + reflected traveling wave = standing wave

What happens to the standing wave when you take away the reflected
wave?

Forward traveling wave + nothing = forward traveling wave

i.e. there is no standing wave. So please tell us again how
you can build a standing wave from a single traveling wave.

... so you can forget about bringing up all of your TV ghost arguments.

That rug of yours under which you try to sweep all the
reflected energy is going to explode one of these days. :-)

Which brings us back to the great loading coil dispute.

In the resonant quarter wave monopole (say 80m), loaded with solenoid coil,
about 2/3 up the radiator, we experience significant (about 40%) current
drop at the top end of the coil. This is also demonstrated by bottom of the
coil getting warmer or hot proportionately, indicating that we have standing
wave circuit and some real current in the system, fortifying Cecil's
argument. RF is flowing along the radiator, "seeing" high impedance tip at
the end, being reflected, flowing back and being superimposed with the
forward wave. Reality that W8JI and other "defenders" had hard time to
swallow.

In the case of traveling wave antenna, like Beverage, terminated with
resistance, we can see the uniform current along the wire. Coil or slinky
inserted in such system will show the same current along the coil (minus
ohmic losses).

There is real life proof about what Cecil is saying above.

Relating to the standing wave circuit, I had question in my mind: how
important is to control the resistance and consider it in standing wave
antenna system. Example is that the current above the loading coil is
appreciably smaller than at the base, hinting that you perhaps do not need
low resistance (copper tubing vs. SS whip).

But...
if the standing wave is made of forward and reverse traveling waves, should
not we be trying to keep the resistance low in the system? Or is it
insignificant?
My pet peeve tells me that it would gain significance in the multi element
loaded arrays. Do the modeling programs capture that? They show slight
increase of current at the bottom (few turns) of the coil (when loading
inductance is properly modeled). Would that be due to the loss from that
point on, when forward and reflected wave is "meeting" the losses to
resistance and radiation and then with lesser amplitude superimposing with
forward wave?
