Hmmmm
They said that the idea of break dancing was an impossibility but they have
classes for same in East St Louis Students are not allowed to graduate
until thay exhibit the ability of removing a hub cap off of a moving vehicle
!
They probably have the same class in The Goebals

Antenna engineers have become so focussed on the half
wave patterns that they have completely ignored the
low efficiency portions at the ends of a half wave
antenna.

Yes, the midldle high current bit generates the H field, but you forget
that the end high voltage bits are needed to generate the E field. The
antenna 1/4 wave physical length is needed to get these in the correct
phase.

Now it should be possible to make a compact antenna where you can
generate the H field from a current element and the electric field from
a voltage element, making sure that the 1/4 phasing is preserved between
the voltage and current. Naah it wouldn't work
