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

So what? If you move off the resonant frequency, your antenna still isn't
resonant. I'd rather have a resonant antenna system on many frequencies
and many bands than an antenna system resonant on only one frequency.

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

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

Depends upon how much money you want to sink into your coax. Open-wire
line with an SWR of 10:1 will beat RG-213 in the loss department on 80m.
It takes 9913 to equal the performance of open-wire line with an SWR of
10:1 on 80m and 9913 costs about three times as much as open-wire line.

And with open-wire line, one can enjoy all eight HF bands immediately,
and not have to spend two days cutting and trying a fan dipole.
