When you get the necessary background to understand how it works, then
we can discuss it intelligently.

But you even think a smith chart can't be used for antennas. So much
for your knowledge.

And also please point out exactly where I said a smith chart could be
used to show the efficiency of an antenna, or what goes on inside a
piece of coax. But you can't - trolls are good at twisting words and
coming up with unsubstantiated claims.

AS I expected more rude personal comments and no real response. It would
appear that anyone who disagrees with you is a troll. I think that you
have show yourself for what you are in this and other threads, and are
incapable of rational discussion. It is you who are the troll. I have
nothing more to say as you do not wish to justify your arguments.

If you understood ANYTHING about Smith Charts, you would understand they
are the graphical representation of the results of mathematical
forumulae. And you obviously don't have the background to understand
the math, so any intelligent discussion is not possible.

Not quite; a Smith chart is a nomgraph of complex impedance usually
noralized to one.

The data could come from "mathematical forumulae" but usually comes
from measured data in which case the "mathematical forumulae" amounts
to normalizing the impedance to one.

From a Smith chart, one can obtain impedances, admittances, reflection
coefficients, scattering parameters, noise figure circles, constant gain
contours and regions for unconditional stability.

I KNOW what a Smith Chart is. But unlike you, I UNDERSTAND the math
behind it.

It's all about the math.
