Just to point out that we don't have measurements of arrival angles at the 
ionosphere proving the fields shown in a NEC far-field analysis, either. 
Yet people seem to accept a NEC far-field pattern as gospel, even though it 
does not accurately show the radiation launched by a monopole at elevation 
angles below 10 degrees or so.
