Rain attenuation measurements in Mississippi at 10 and 14.43 GHz

A comparison was made between 10- and 14.43-GHz microwave relay performance in northeastern Mississippi during periods of heavy rainfall. Rainfall rate on the 4.7-km test path was obtained from 20 tipping-bucket gages. Measured attenuation (in dB) at 14.43 GHz was approximately twice that observed at 10 GHz when the rainfall rate exceeded 50 mm/h.
