I've received a number of emails requesting that I
explain what I meant by this statement. It is easiest
understood by people who can solve the following
problem.

How can the impedance looking into the following
physical 45 degree, dual-Z0 stub be purely resistive,
i.e. electrically 90 degrees and resonant?
