On antennae that are several half-wavelengths long (beverage, Rhombic, etc)
what does the radiative wavefront look like when close to the antennae,
even
though it is presented in the literature as a plane wave further out?

The reason that I ask is the on such longwires, there are parts of the
wire which will be radiating positively, and parts negatively, thereby
suggesting that the outgoing wave, spherical though it might be, has
a +/- modualtion were you to travrse its circumference?

Parts of the wire have negative radiation? Outgoing wave has
circumferential modulation?

OK, I get it now. You aren't being serious.

He is confusing the E and M fields, which have a sine form but in
orthogonal planes, for 'the radiation', in essence
he doesn't understand the nature of an EM wave.

Once again, Brian, the origination of abuse comes from you, and yet
you don't know enought yourself to discuss the matter, so you do not.

They are not planar, but 3D fields.
