Hi Jim,

3D in two-space? No.

I'm not sure that really tells us very much about the antennas themselves.
You'd need to surround each of the antennas with a
uniform field in order to compare them. By uniform, I mean the field
intensity toward the antenna is the same in any direction.

The problem has symmetry on its side, additional source add to the
dipole in equal measure to the yagi. Adding more power does not
create the missing power already lost.
