Here's the example sans the Bird. Between the tuner output

exactly is the actual SWR = 2.25:1? Answer: nowhere!

XMTR--tuner---1 WL 75 ohm coax---50 ohm load

And the answer would be different still in this circuit.

XMTR---1/4 WL 75 ohm coax---50 ohm load

No, it wouldn't. The answer is exactly the same. *NOWHERE* is
the SWR 1:1 or 2.25:1. In both examples, the SWR on the coax
is 1.5:1. The SWR is *always* set by the relationship of Z0
to the load. In both examples above, that relationship is
*identical*.

Amazin', what happens when you change the circuit!

Z0 didn't change. The load didn't change. Therefore, the
SWR didn't change. What exactly do you think changed?
