The different rain attenuation prediction models proposed by different authors on terrestrial paths are studied in this paper. Subsequently, for paths not exceeding 22 km, the rain attenuation exceeded for 0.01% of the time for these four geographical locations is estimated for South Africa using the ITU‐R Model, the Crane Global model, and the Moupfouma model, at different frequencies. Finally, the predicted attenuation values are compared on a monthly basis, as well with the measured upper and lower attenuation bounds for a 6.73‐km line‐of‐sight link operating at 19.5 GHz in Durban.
