Radio Propagation Over Plane Earth-Field Strength Curves

Abstract

Curves are presented to facilitate the calculation of radio propagation over plane earth. The magnitude and phase of the reflection coefficient for all conductivities of interest and for four values of the dielectric constant are presented in the form of curves from which the significant quantities may be read with the same degree of accuracy for all conditions. Simple equations, from which the effect of raising the antennas above the earth's surface may be readily calculated, are presented.
