The purposes of my post were to state that (1) many NEC evaluations show a
combination of the radiation from the antenna PLUS the propagation effects
for the chosen earth parameters and antenna elevation, and (2) even when
such an approach shows zero field in the horizontal plane for a ground
mounted vertical monopole up to 5/8-wave high, that h-plane field in reality
is NOT zero _as it is radiated_ by the antenna.
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.
