Abstract: Microwave propagation characteristics over hilly terrain situated in southern India have been presented. Amplitude measurements at 7.6 GHz were made round the clock during Mar 1981-Apr 1983 using an operational communication link The daytime signal is characterized with fast and small amplitude fluctuations of the order of 2-3 dB while during night and early morning large amplitude variations sometimes as high as 20-25 dB are observed. High fade rates have been observed to be dominant during premonsoon months. The distribution of fade rates indicates that during monsoon and post-monsoon the fade rate is 30-40 (fades) per hour and the fade rate is 150 per hour in premonsoon while it is 90 per hour in winter.
