Zo of ALL real, ordinary, transmission lines changes versus frequency over
a
very wide frequency range.
Zo ranges over lots of thousands of ohms at a few cyles of seconds,
thousands of ohms at power frequencies, hundreds of ohms at audio
frequencies, and from tens to a few hundred ohms from 100KHz up to as many
GHz as you like.

Are we talking the same thing for Zo ? That a piece of say rg-8 ( whatever
they want to call it now) that is 50 ohm coax is not 50 ohms over its normal
operating frequency range ?
