Abstract
This paper presents the experiment result of rain attenuation data measurement in Ku band downlink of Thaicom 2 to find the relation of rain fade time and attenuation loss at each level. By using the computer to record and process data we received this relation which has attenuation level of 2-13dB ranges for fade duration intervals of 0.5-5min, 5-20min and more than 20min to observe the characteristic of rain fade time at the difference period of raining. This experiment has been held a half of year from July to December 1999.
