Sorry, I am just quoting Owen's results. There was 4.1667 watts
of reflected energy flowing back through the Bird. The Bird
indicated zero watts. That's an infinite percentage error on
reflected power for the Bird and proves my point that a 50 ohm
wattmeter used in a 75 ohm environment is like using a hammer
on a screw. To paraphrase: when the only tool one has is a 50
ohm Bird, every Z0 environment looks like 50 ohms.
