What about figure 2, Cecil?

Figure 2 suggests that any coil with a delay over 15 degrees
should be analyzed by discarding the lumped circuit model
and instead using the distributed network model. Every coil
I have talked about on this thread has a delay greater than
15 degrees. 15 degrees of impedance transformation will transform
50 ohms into 54+j120 ohms with a difference in SWRs of 7 to one.
Does that really sound like a reasonable reason for keeping the
lumped-circuit model?

Roy just said in another posting that the reflection model
will solve all the problems that the lumped circuit model
will solve. It just gets clumsy as far as the math goes.

It is interesting to watch the gurus retreat into fantasy
where they were only ever talking about tiny point inductances
to start with. Anyone who has been following this argument
over the years knows otherwise.
