If there is a mismatch at the antenna (and there is no matching at the

match is applied at the transmitter end of the feedline.

Surely a conjugate match will only match the load if the coax length is
1/2 wavelength or multiple thereof, and the feeder is also lossless.

Any other coax length will introduce a phase shift that will require a
different match.

You just have to match whatever impedance the aerial impedance has been
transformed to at the transmitter end. Then you will get maximum power
into the radiation resistance of the aerial (less the second order
losses in the feeder). A remaining reactive mismatch between the feeder
and the aerial will result in increased voltages and currents and
increased feeder loss (a second order effect at HF) but will not prevent
substantially full power transfer. We had this discussion about very
short aerials quite recently, You have to have a very extreme radiation
resistance for this not to work. Choosing a length of aerial with no
extreme values on the bands you are using is where we came in.
