So, am I to take this response to mean that you have no further

comment upon your statement:
In fact for distances just into the far-field region for the radiator
defined in (2) above (far field usually being defined as further than
2H^2/lambda from the antenna), h-plane relative field is virtually 100%,
regardless of ground conditions.


as rebutted by mine:
As I pointed out once before, NEC (EZNEC in particular) will exhibit
fields from any antenna that are consistent with Brown, Lewis, and
Epstein's field data to within 1dB.

By way of elaboration, this INCLUDES at zero degrees.

AFAIK, neither NEC 2 nor NEC 4 from any source will show a composite
elevation pattern over a defined ground at a specified distance to include
the space wave and the surface wave in a single display. One must merge
them using his/her own understanding and resources.
