Abstract
The ITALSAT propagation experiment, started in early 1991 and still on-going, allows an extensive program of measurements at 18.7, 39.6, and 49.5 GHz. This paper reports the results obtained so far from copolar signal measurements carried out at the Earth station of Spino d’Adda from 1993 to 1995. Statistics of rain and total attenuation and frequency scaling of total attenuation are presented and commented in the light of the ITU-R predictions
