Three experiments were set up within a joint African radiometric propagation measurement programme to provide data at frequencies above 10 GHz for predictive modelling. The results of the first year of measurements in Ile-Ife, Nigeria are reported. Compared with CCIR predictions, the rain measurements agree fairly well but the path attenuation results differ significantly.
