Three-site Ka-band diversity experiment performed in Slovenia and Austria

The paper describes an ongoing site-diversity experiment performed in central Slovenia and southern Austria. Three synchronized Ka-band satellite beacon receivers of the same type have been used for this purpose. Two of them are installed in Slovenia, measuring a 20.2 GHz beacon from ASTRA 3B. The third receiver is located in Graz, Austria, measuring a 19.7 GHz beacon signal from Alphasat. The measured attenuation time series are statistically analysed for each of the three single sites, the three pairs of the sites and the combination of all three sites. The results show the gain obtained as a result of site-diversity and, in case of combinations with Graz station, partially also as a result of satellite-diversity. Finally, the results are compared also to the existing ITU-R models.
