An improved and enhanced version of a model for outdoor propagation at frequencies from 50 MHz up to 1 GHz is presented. The model, as well as the original one are mathematical characterizations of the FCC propagation curves F(50,50). Some limitations of the original model have been mastered in the improved version presented here, namely, the model has been extended for distances of more than 40 mi (64 Km) and antenna heights up to 1800 m. Like its predecessor, the new model allows for the estimation of the median path loss, received power or electrical field strength, which usually is sufficient in a vast majority of practical applications for which a deeper knowledge of channel dynamics is not necessary.
