Coparison of measured and theoretically predicted results of ground-wave propagation characteristic at MF-band

This paper presents the comparison of measured and theoretically predicted results of ground-wave propagation characteristic over a land-sea mixed-path at medium frequency (MF) band. One of techniques employed here is the theory given by Rotheram, and the other is the empirical formula for mixed-path problems developed by Millington. It is shown that the theoretically predicted and experimental results are in good agreement.
