Abstract:

Curves that may be useful for establishing preliminary allocation plans were prepared for a fixed combination of antenna heights and assume propagation over a smooth earth. They make no allowance for a wide range of propagation path profiles or atmospheric conditions that may be encountered over particular paths. A method for computing preliminary reference values of transmission loss is described. It is based on a simple model, may readily be programmed, and is especially useful when little is known of the details of terrain.
