Sorry, I am just quoting Owen's results.

There is nothing in his entire scope of postings that presents:

There was 4.1667 watts of reflected energy flowing back through the Bird.

Which is absurd.

The SWR on the 75 ohm line is 1.5:1. If 100 watts is delivered to
the load, there's 4.1667 watts of energy reflected from the load
and flowing back through the Bird. The Bird doesn't see it because
the Bird is calibrated for the wrong Z0.

Owen has demonstrated quite clearly that your assertion

It takes a certain length of feedline to establish a Z0 environment

is blarney from one end of your feedline to the other.

Really? They why bother with characteristic impedance at all?
If Z0 doesn't establish a Z0 environment, then all transmission
lines are just alike and transmission theory is hogwash.

Cecil,

I can't figure out which side you are on. There is no Z0 environment set up;
the Bridge is balanced for a chosen Z0, actually R0.
