Abstract : A comparison was made between 10 GHz and 14.43 GHz microwave relay performance in northeastern Mississippi from February to May 1969. Interference fading caused by atmospheric multipath did not exceed 15 dB on either system, but as much as 48 dB attenuation was observed at 14.43 GHz during heavy rain. Rainfall rate on the 4.67 km (3 mi) test path was obtained from 20 tipping-bucket gages. A method of estimating rain attenuation for relay design and reliability problems is presented and general storm rainfall information is included. (Author)
