Abstract :
We present here the results of measurements of rain-induced attenuation in the vertically polarized signal propagating at 19.4 GHz over a 2.29-km line-of-sight (LOS) link during some rain events, which occurred in the monsoon season of the year 2001 at Amritsar, India. The total attenuation over the link path measured experimentally has been compared with that obtained using Marshal-Palmer (MP) drop size distribution and Medhurst´s theoretical values and International Radio Consultative Committee (CCIR) model. Our measured results are in excellent agreement with the MP prediction.
