A lumped component is not enough to make the model correct.
Comments welcome.

Hi Dan,

It works both ways. However, lines can appear to be equivalent to
lumped components until you, say, double the frequency. The two
models clearly diverge. Where you could place a series resonant
lumped circuit in place of a resonant line (or versa vice) at a
fundamental frequency, the lumped series circuit would rarely
demonstrate parallel resonance at twice that frequency, but the line
would.

But it appears the model hasn't been constrained to less than an
octave bandwidth - until after Keith submitted the winning ticket to
the lottery commission. Cecil's lotteries are like that. To date
(more than 12 years now) you are the only winner, and I haven't seen
your prize awarded yet.
