Yet another reason why the so-called swr meter does not measure swr is
because there is no transmission line (between meter and transmitter) on
which to measure it. SWR on it cannot not exist.

The consensus of opinion over on science.physics.electromag is
that a two foot long section of 50 ohm coax is all the length
needed to force the V/I ratio to be 50 ohms at HF - something
to do with the length Vs separation between conductors ratio.
That V/I ratio = 50 is the assumption made by the SWR meter
designer when the meter is calibrated.
