I prefer non-resonant antennas and transmission lines that resonant them.

:-)

It's "resonate", Cecil, and the antenna still won't be resonant.


You just can't beat a resonant antenna for radiation.


Maybe not, but you can equal them. A tuned transmission line resonates
the antenna system.


When you get a lossless line. And the antenna still isn't resonant.


Tuners squander AT BEST 1 or 2 db.


That's why I don't use a conventional tuner.

So build your antenna resonant, match it, and don't bother with a tuner.


Or build your antenna non-resonant and match it with a series section
transformer.

If impedance transformation is necessary, use a transformer;


IF impedance transformation is necessary, use a transmission line
as the transformer. :-)


Not the least lossy approach.
Matched impedance = max power transfer.
