Abstract

Results of UHF signal propagation measurement performed in a typical highway environment using various types of antennas are presented. Then, double regression curves employing the first Fresnel break distance are fitted to each set of measured data. Standard deviations smaller than those of urban environments are obtained, which can be used to reduce the fade margin and increase base station coverage significantly. Field behavior under the two-ray model is revisited
