Propagation of Radiowaves — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

The principal modes of radiowave propagation at frequencies below 2 MHz are the surface wave and sky wave. In this Chapter these two modes are introduced and described. Rather than concentrate on the details of elaborate path loss prediction theories, they are merely introduced and the discussion then concentrates on their application by the planning engineer. The sky-wave propagation prediction methods described in this Chapter are only applicable at frequencies below 2 MHz. However, the surface-wave models are based on more general theories and can also be applied in the HF band. Antenna and external-noise aspects of system planning are discussed. Throughout, readers are directed towards relevant data sources, prediction procedures and computer programs so that they might apply the planning methods described.
