Modelo de propagación para exteriores a frecuencias de 50 MHz a 1 GHz

A model for outdoor propagation at frequencies from about 50 MHz, up to 1 GHz is presented. The model is of very simple utilization and in fact, it has been widely used in graphical form by many practical engineers during more than fifty years. Our model is a mathematical characterization of the propagation curves F(50,50) of the Federal Communications Commission (FCC) of the U.S., and can easily be implemented, either in a computer or even in a simple programmable hand calculator
