There you go again, trying to shove your words

You have apparently done the math and found it
to be valid so, once again, you have to change
the specified conditions in order to try to make
your point.

A Z0 of 50 ohms is the *only* characteristic
impedance that will meet the specified precondition
of zero average interference. Choosing any other
characteristic impedance will move the example
outside of the scope of my Part 1 article. I
understand why you want to do such a thing but
obfuscation, diversions, and straw men are not
part of the scientific method. My Part 1 article
has a very narrow scope. Please abide by it.

Killing a snake and using it for the transmission
line would likewise violate the same specified
preconditions. Please feel free to do that and
report the results.
