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.
