Abstract :
This paper presents results of differential attenuation measurements in 6 terrestrial line-of-sight microwave links with a common end at Sao Paulo, in the tropical region of Brazil. One link operates at 18 GHz and five links at 15 GHz. An empirical method used to estimate the differential attenuation exceeded at a given percentage of time as a function of the angle between links and their path length difference was developed based on the experimental results
