And as has been repeated a number of times between myself and Richard Fry,
the right tool is needed to obtain accurate low-angle results from a
base-fed monopole. One such tool is 4Nec2's surface wave modeling
application when running under NEC4. The surface wave tool is designed
expressly for low-angle modeling just above the earth's surface.
The surface wave tool most be used in conjunction with the normal modeling
application to get a complete and accurate vertical profile from 0 through
90 degrees.
