About this ebook
A simple integral formulation is given for the radio wave power propagating between the curved earth and the ionosphere for the case of low frequency transmitters on the surface of the earth. By making assumptions about the vertical field profiles, the field strengths at arbitrary distances and altitudes can be estimated. Field strength versus distance predictions are compared with published mode and wave-hop calculations and with experimental data.
