RL If I connect a 50 ohm source to a one wavelength, 300 ohm transmission
RL line and connect the other end of that line to a 50 ohm resistor,
RL there's a 6:1 mismatch at both ends of the line.

RL No loss is caused by the mismatch. No "scattering of energy occurs".
RL All of the energy from the source arrives at the load, where it was
RL intended.

So why bother with high priced cable when a piece of clothes hanger
will do just as well, encantations? I think your are still in April 1
mode, Mr.Roy. We are way past diatribe here, thank you.

What Roy actually said was:

"If I connect a 50 ohm source to a one wavelength, 300 ohm
transmission line and connect the other end of that line to a 50 ohm
resistor, there's a 6:1 mismatch at both ends of the line. The power
supplied by the source and the power delivered to the load are exactly
the same as if I had used a 50 ohm line instead. This is, of course,
overlooking resitive loss in the line. If you consider the resistive
loss, it can be greater in one line than the other (the 300 ohm line
might be less lossy), depending on the physical construction of the
line."

So you see, our shyster poster left out the part where Roy considers
that resistive loss plays a part, and by inference makes copper wire a
better choice than clothes hangers.
