Dave,

I agree with you that the antenna itself need not be resonant.

Though I'd say that when an antenna tuner creates a suitable
matching network for that non-resonant antenna, we can properly say
that the entire antenna system of tuner plus feedline plus antenna
has been "tuned".

I didn't see anything at to convince me otherwise.
DIgging around some on his website, I find this on

IT DOES NOT 'TUNE' THE ANTENNA! NEVER! (with one exception)
To do that, the matchbox would have to be located at and be a physical part of the antenna.
AND IF IT WERE PART OF THE ANTENNA, IT WOULD NOT NEED A SEPARATE NAME AND DESCRIPTION!
But it does match the antenna and its transmission line (the antenna system) to the transmitter.
Therefore I prefer to say "match" and not "tune".


So he figures something that "tunes the antenna" must be physically part of the antenna.
OK, fine with me, but that strikes me as a rather silly distinction.

Perhaps we can all agree that an antenna tuner tunes the "antenna system",
where the antenna system includes the tuner, the feedline, and the antenna.

Also, on that same page he says:

NOTE 1: [very important!] Just because the matchbox is able to match the antenna and transmission line to the transmitter with a perfect match (SWR = 1.0:1), that does not necessarily mean that all of the power being passed through the matchbox to the antenna.
THERE IS ALWAYS SOME POWER LOSS WHEN USING A MATCHBOX.
THIS IS VERY IMPORTANT TO UNDERSTAND.
NOTE 2: [and also very important!] Just because power is efficiently transferred into the transmission line (with very little loss inside the matchbox), do NOT assume the it effeciently arrives at the antenna! Don't make that mistake! ? Transmission lines, ESPECIALLY COAX, can add significant loss to the antenna system.


That strikes me as a bit over the top.
If the antenna is somewhat close to a match to begin with, perhaps a 3:1 or 4:1 SWR
so the reflections aren't just too severe, and if the coax is not terribly lossy,
then at HF you probably don't lose enough power in the coax for the guy at the far end to even notice.

Maxwell's "Reflections III" makes the case in section 4.4,
Later in the book he gave a more definitive formula for the loss, but I'm not finding it just now.
The organization of that book is more than a little bit scattered.
It is legitimately available on the web as a pdf.

And if you are worried about those coax losses, use ladder line.
Then even with some really drastic reflections between antenna tuner and antenna feedpoint,
the antenna system will still radiate power efficiently.
