Abstract :
The renewed interest in the use of the medium wave band for broadcasting purposes makes it necessary to evaluate if the prediction methods used for network planning of the analogue services are accurate enough for the new digital transmissions. The Millington method, included in the ITU-R Rec. P.368-9, is a semi-empirical method that considers non-homogeneous terrain paths composed of sections with different lengths and conductivity values. The aim of this study is to empirically analyze the accuracy of the Millington prediction method in the specific case of land-sea-land propagation paths. Furthermore, a method for minimizing the effect of conductivity inaccuracies in the field strength predicted values is proposed.
