I have ordered a copy. From what I have read of Chipman so far,
everything can be explained by achieving a conjugate match at
one point on the transmission line when the reactance looking
in either direction is at a maximum. This is simply a resonance
effect. Here's a bench experiment that might shed some light
on this problem.

source--50 ohm coax--(-j500)--SWR meter--(+j500)--50 ohm coax--50 ohm load

There is a localized high reactive energy exchange through the SWR meter
between the capacitance and the coil but nowhere else on the transmission
line. That has got to have an effect on the SWR reading which is probably
not good. What, exactly, is the big deal? It is just another distributed
circuit problem.
