"There is and always will be a need to present the transmitter with the
lowest possible SWR, regardless of if it is accomplished with a well-tuned
antenna or if that is not possible, inserting an antenna tuner between the
transmitter and antenna"

====================

Many years ago when transmitters had tuneable outputs, matching cud be achieved
by something called a "pi network" in the transmitter box.

This circuit resonated the final plate circuit and provided a match to the
sending end impedance of the tl. Granted the magnitude of the SWR, i.e.,
degree of mismatch, it wud match wasn't as much as modern day "tuners".

They are not antenna tuners. If they were they wud be located at the antenna,
not the hamshack.

Jack, I guess all the manufacturers that sell "antenna tuners" are totally
wrong about what it is they're manufacturing and selling. If I were you, I
would go after all the "antenna tuner" manufacturers in the below URL and
tell them they're all wrong.

They'll thank you for correcting them...

Jerry, that was an impressive list of tuners. But did you note that not all
of them were listed as "Antenna Tuners". Some of them were designed to sit in
the shack next to the rig. These tune the antenna plus the transmission line
system as a whole. They don't get the SWR's down, SWR remains the same on the
antenna system.
Others on the list can be mounted right at the antenna, and fed with 50 ohm
coax. They get the SWR's down on the transmission line because the 50 ohm coax
sees a Zo match.
Others on that list can be placed in the shack or at the antenna. The
function is to transform whatever impedance the tuner sees to 50 ohms. Tuner
in the shack, no SWR change, at antenna, yes. So, "Antenna Tuner", what's in a
name?

Exactly. My point was the ragging on the "antenna tuner" term and one ham
trying to display his brilliance to the world by pontificating on exactly
what an antenna tuner is supposed to be. If someone can't use a commonly
used term with MOST of the world understanding what is meant without some
know-it-all jumping on it to point out some minor technical mis-use of a
term, then it's time to wonder his motive.

It's no use. They wouldn't believe me.

I tried to explain to someone once that buffalos don't have wings. The didn't
believe me either.
