ok, so for an isotropic antennae the radiation pattern is uniform in all directions (i.e. a sphere). So for this pattern, is there a formula for determining the diameter of the sphere, or is such a measurement meaningless?
also, suppose a groundplane an arbitrary height below the antennae, the ground plane would reflect the signal and look something like this??
