This work presents the results of a terrestrial multiple-receiver radio link experiment at 10.7 GHz. Results are shown in the form of the power levels recorded at several antennas attached to a receiving mast. Comparisons of the measurement data with theoretical predictions using a parabolic equation technique show that, due to the complex propagation environment of the troposphere in terms of ...

Radio programmes are increasingly available not only from terrestrial networks but also from a large variety of satellite, cable and, indeed, telecommunications networks (e.g. fixed telephone lines, wireless broadband connections and mobile phones).
