Observational investigations of rain attenuation on earth to satellite path of JCSAT-II at frequency 12 GHz has been conducted with the use of large aperture parabola antenna which has 5.6m in diameter at Takushoku University since 1997. In addition, experiments of site diversity, which used two stations spaced 5.7km apart to guarantee a high quality of satellite link, were carried out between Takushoku University and Tokyo University of Institute stations from May 1999 to July 2002. This paper describes not only experimental results and discussions of rain attenuation duration time on site diversity, but also topics of rain events and rain attenuation, i. e., rain types, rain rate distribution, theoretical explanation of rain attenuation prediction method, evaluation of site diversity method and characteristics of rain cell behavior. These topics were not mentioned in previous two papers under same title, because of limiting by the amount of pages.
