If the loss per unit wavelength is large enough, and you produced a plot of
voltage vs. distance x. The voltage maximum would be at the source, and the
voltage minimum at the load. Try a thousand miles or so of RG58 at 60 Hz.
I suspect that to see anything that looks like a standing wave you would
have to look at dV/dx. Remember, I can always define a lossier line.
