My poor knowledge of antenna systems think that the ATU, choosing the

If you perform a frequency sweep with an antenna analyzer connected to
the tuner input and the impedance goes from R-jX ohms to 50+j0 ohms to
R+jX ohms, the purely resistive frequency meets the definition of the
*system* resonant frequency. Unfortunately, under those extremely
lossy conditions, "system resonance" means almost nothing.
