Velocity = frequency x wavelength.

The product, frequency x wavelength must be infinite if velocity is
infinite.

Directors and reflectors in parasitic antenna arrays exhibit phase
(time) delays which depend on element spacings and these spacings are
likely within the near field. I`ve never heard of any velocity
corrections to the phasing required by near field immersion.

I`m missing something here.
