The theoretical gain of a GP with horizontal radials, radials drooping
45 degrees and and drooping 85 degrees is 1.42, 2.22, and 3.67 dbi.

I would have thought that the 'ultimate' would be when the droop IS 90
degrees (ie essentially a sleeve dipole).

With a droop of 90 degrees, is the gain slightly more than 3.67?

How come that you can have a 1/4 wave radiator groundplane type of
antenna with a gain that is more than a halfwave dipole (2.15 dBi) -even
if it is more-or-less a sleeve dipole?
