There are models for both lossy and non lossy transmission line. I have not
used them, so it might take some learning. I can tell you though that given
a load and transmission line, if you find the Z at the meter with an HP
vector impedance meter, and then put a lumped impedance of that same value
at the meter, you will get the same results.

Not in reality, you won't. Any TV ghosting that exists because of reflections will
disappear when you go to a lumped impedance. And the noise across the lumped
impedance will not be identical to the noise associated with a long transmission line.
