Check for reflected power in either direction.
If none, then it is conjugally matched exactly.
If it is about -14 dB down, that is good and close enough.

One can try to measure Tx output Z (looking into Tx) and then the Z looking
backup the antenna line, and try matching the two as a start,
but reflected power quicker, faster, more accurate.
(also I agree with you in trying to measure Tx output Z (looking into the
output)
tried and got a mess many times,...)

Indeed it is. R+jX one way and R-jX the other.

Why the vast amount of palaver and bickering about such an obvious and
elementary notion defeats the imagination.

Reg, you are in a room with a transmission line passing through it.
You measure all voltages, currents, and powers. How do use your "obvious
and elementary notions" to tell if the transmission line is conjugately
matched or not? How do you measure the impedance looking toward a typical
amateur radio transmitter without changing the very thing you are trying
to measure? Many have tried and many have failed.
