Default opinions on an antenna idea

If one were to find lossless material (superconductors?) for the short

No. The answer can be found in any antenna textbook,

etc.

Thanks Roy. Unfortunately, since I retired, I no longer have access to
Jasik, Kraus etc. So, thanks for the answer. I should have realised that
a dipole of any length is still a dipole and as such will not radiate
off it's ends. Mind you, Eznec shows the average dipole, less than
half-wave above ground, goes pretty close to an isotropic radiator for
all practical purposes
