No gain in a pure isotropic source?

Hi Butch,

There is no gain in any antenna. An isotropic source represents a
reference. One may choose any other antenna, a dipole being a common
basis of comparison.

In this sense of comparison, gain as a term then becomes an indicator
of differences between the subject at hand and the reference.
