Abstract :
This paper presents an analysis of the ground wave propagation in the 26 MHz band based on a comparison between measured and predicted field strength values. To do this, a set of empirical data obtained from a measurement campaign of a DRM experimental local service was used. Simulated field strength values were calculated applying two different models that account for the space and surface wave propagation respectively. The corresponding prediction errors were analyzed and a correction factor due to the terrain irregularity was obtained in order to increase the accuracy of the results.
