Clearly in a center-fed half-wave dipole, if there is no load at the

Maybe you would like to rethink that, Tom. Consider a parasitic 1/2WL
element on a Yagi. The currents at the ends are obviously zero. The
current 1/4WL away from the zero points are the maximum current
points. If you short across the feedpoint of a 1/2WL dipole, it will
be resonant but the center will be a current loop (antinode), i.e.
a maximum current point. The center of a *one wavelength* dipole will
be a current node.
