The attenuation of radio frequency waves traveling along the surface of finitely conducting earth is computed. Vertical polarization and a flat earth are assumed. Results are shown in graphical form. One set of graphs shows the electric field intensity produced by a short monopole antenna as a function of distance from the antenna. Another set shows the attenuation of a vertically polarized wave as a function of distance for any antenna. Four different sets of typical ground constants were used for the computations. The computations are based on a slightly modified form of Nortons equations. The modifications are shown in an appendix. Author
