IMO, the resistor load simplifies things as a single-port analysis can
be used on a resistor because there is only one component of power
accepted by the resistor. What would complicate things, IMO, is a 50
ohm antenna feedpoint impedance which is a virtual impedance.
Analyzing the antenna as a multiple port device shows where the
multiple energy components go which is a complication of the present
point I am trying to make about the Z0-match point 'x'.

However, the single-port vs dual-port analysis differences at the
impedance discontinuity 'x' also apply to the analysis at the load
resistor vs an antenna AND at the source where Walt seems to be using
a single-port analysis involving a virtual source impedance which
depends for its very existence upon forward and reflected energy
components flowing in opposite directions at the source impedance
point which necessarily causes interference accompanied by a
redistribution, not a reflection, of energy components.
