Rich, you are a master at cut and paste editing where you twist everyone's words.

THIS is what I wrote:

Quite a bit different than the hatchet job you did, Rich.  Changes the meaning of the entire post, doesn't it.  Please use a little more care to properly quote people in the future.

Jim's antenna has much worse than a 2.5% mismatch.  If he had no tuner, the reflected power at the PA would be sent back to the antenna.

However....

Let's say that Jim's antenna DOES have just a 2.5% mismatch.  I will assume a lossless transmission line.  2.5% of his power will be reflected back down the line and without a tuner will end up at the output of his PA.  Now, SOME of that power will be absorbed in the PA and SOME of it will be reflected back up the line.  Only if output of the PA looked like a short or an open circuit would the entire 2.5% be re-reflected.  And if the output of the PA looked like a short or an open, no power would get out of the PA in the first place!

So you are still incorrect.

Of course, what does it matter to try discussing anything with you, Rich. You twist and manipulate everything that anyone else says to gratify your ego.

You should be a politician or a laywer.
