In this article the measurement results and their comparison with simulation results will be shown. The obtained measurement results prove for the first time in the technical literature the real occurrence of many selective fading in the DAB + signal band. The high compliance of the measurement results of the fade characteristics with the simulation results, which were also presented in the article, indicates the possibility of predicting the areas and characteristics of fades on the basis of simulation tests. Thus, on their basis, it will be possible to determine the places where this phenomenon occurs and take it into account in the process of planning the SFN network.
