"Properties of Free Space"

Permeability = 1.257 * 10^-6 henry per meter.
Permittivity = 8.85 * 10^-12 farad per meter.

Characteristic impedance = sqrt(Permeability/Permittivity) = 376.7 ohms

My earlier citations of reputable sources were denounced as being an
intentional insult. I see that yours is simply being ignored. Perhaps
that's progress?

Well, he is correct, you were wrong with your SQRT(1/1) = Zo = 1. If you use
his values, you will get the proper value (377 Ohms) so he is correct. Glad
you finally saw the light.

Anyone reviewing the previous few postings on this topic surely must
feel he's dropped down a rabbit hole. I certainly do.

I've got to plonk this guy so I don't waste any more time on this sort
of silliness.
