Doesn't the impedance transformation ratio have an effect on the

The question is not: Can a particular pi-network plus
load be 30-50% efficient? Certainly, it can.


No disagreement, Cecil. My question
wasn't intended as a response to your
post. Sorry about that.

The question
is: Are all pi-networks 30-50% efficient? The answer is "No!".

If that is the question, then no
disagreement there either.

We don't know all of what W8QUR said,
and none of what he meant, but there are
contexts in which each of his three
assertions could be correct. I guess the
one thing he doesn't seem to have said
is that all pi-networks are 30-50%
efficient. ;-)
