Abstract :
This paper present the contribute of rainfall rate and rain attenuation in Ku band measurement and prediction rain attenuation in Ka band by using ITU-R model at King Mongkut´s Institute of Technology Ladkrabang (KMITL), Bangkok, Thailand. One year measurement of rainfall rate and rain attenuation of Ku band satellite signal of 59 degree elevation angle is presented. The experimental results, we found that on the rainfall rate R0.01 is 90 mm/hr, the measured Ku band rain attenuation A0.01 about 11 dB while predicted Ka band rain attenuation is 20 dB, The effect of rain attenuation characteristics of Ka band and Ku band satellite signals are compared
