Now Reg, you have to admit that an SWR meter that can read
the SWR on the 92 ohm feedline when installed at point 'a'
is a darned smart meter. :-)

Of what use is a meter which tells you what you already know?

I don't already know it, Reg. The impedance of the load is
unknown so the SWR is unknown until measured.
