The following shows the effect on elevation pattern for a 1/2 wave
dipole antenna over ground at various heights for perfect, very good,
average, and extremely ground.

The important value to note is the elevation angle for the main lobe.

Perfect V good Avg Ext poor
Height gain @ elev gain @ elev gain @ elev gain @ elev
0.10 8.6 90 6.3 90 4.4 90 3.1 90
0.15 8.4 90 7.1 90 5.8 90 4.3 90

I'm having trouble wading through the data, probably because of column
headings. Let's take the first line.

0.10 Would be the height
I get lost after that.
Is 8.6 the gain over perfect ground, 6.3 over good, etc.
What are the 90's?

Height is the height in wavelengths.

gain is the gain of the main lobe.

@ elev is the elevation angle of the main lobe; 90 means straight up.

And there are three sets for perfect, very good, average, and extremely
poor ground.

It all lines up in ASCII; if the spacing is screwed up, you are likely
viewing it as HTML.
