So, you start off with a quiescent piece of wire, and launch a wave into it,
some of which will be radiated. The rest is reflected off the end, and
arrives
back at the feed point, the open end causing a reversal of the current, and
in a
short antennae, the current arriving back at the feed point is out of phase
with
the voltage and so the antenna appears reactive.

So, for those who deny that some of the power is not radiated, whence does
the reactance arise?
