"Field in mV/m for 1 kW at 1 km Elevation pattern----"

Richard`s field strengths are consistent with Terman`s formula for
field strength on page 864 of his 1955 opus, equation (23-1):

E = 60pi/d (length/lambda) I cos theta (cos omega) (t-d/c)

Theta is the vertical elevation angle and, of course, at zero degrees
(the horizontal) cos theta =1, and at 90 degrees, cos theta = zero.
This gives the field strength from an elementary vertical doublet as
diagrammed on the next page. Omega is the angular frequency. I is the
uniform current through the element.

Terman says: "The laws governing such radiation are obtained by using
Maxwell`s equations to express the fields associated with the wire; when
this is done there is found to be a component, termed the radiated
field, having a strength rhat varies inversely with distance."

The 1/4-wave vertical along with its image in a perfect ground is shown
on page 887 to have the same elevation pattern.
