For me it is important that at the end the voltage is doubled: "At the

of a resonant antenna there is almost double the forward voltage".

The same thing happens with an open-circuit stub yet it
radiates a negligible amount. The only place where an
antenna radiates more than a negligible amount is where
the forward and reverse currents are unbalanced.

At the ends of a 1/2WL dipole, the forward and reverse
currents are perfectly balanced, i.e. they are 100%
transmission line currents which are known not to
radiate.

At the 1/2WL dipole feedpoint, the forward and reverse
currents are most unbalanced, i.e. since they are in
phase at the feedpoint, they can be considered to be
100% antenna currents.

This is just one more example of the illogic of
forcing forward and reflected waves into a mashed
potatoes theory of energy. The underlying laws of
physics are lost in the process.
