Cecil, hopefully you understand that even isotropic radiators near each

Maybe I'm misunderstanding you.

I'm trying to understand how a line drawn between two
"isotropic radiators near each other" could ever be
in the far field.

Everywhere it exceeds 2*D^2/lambda in length, where D is the greatest
dimension of the array.

Are you saying that the sources that are "near each other"
are far enough apart to be in each other's far field?
How could that be if the two sources are D apart?
