Abstract—This paper deals with the short (10 km) and long dis-tance (300–1400 km) site-diversity (SD) characteristics by using a newly developed measuring system. In the proposed measuring system, six earth stations transmit 14-GHz band QPSK signals, and one measuring earth station receives 12-GHz band signals and processes them to determine SD characteristics. As a result, easy operation and maintenance, low-cost measuring system construc-tion and highly accurate data have been obtained. By comparing those measured results with the SD joint probability approxima-tion equation in ITU-R Rec.P.618-7, a good agreement can be ob-tained. Furthermore, the effect of typhoons on SD characteristics were measured.
