Propagation Measurements and Analysis on MF and HF Bands in Urban Areas in The Netherlands

Using a new propagation measurement set-up, which produces a high number of data, enabling a proper statistical analysis, and resulting in very concise results, propagation measurements were performed and analyzed at 16 residential locations in The Netherlands in the frequency range from 1.8 to 28 MHz. In the whole frequency range the propagation loss appears to be higher than might be expected according the International Telecommunication Union ground-wave propagation model. Also typical characteristics of that model are not present, but instead the propagation shows a constant roll-off in dBs per decade, with a slope increasing with frequency. A regression curve could be established, and constants filled in. This statistical information may be used for building an accumulation model to lay a causality between source powers, source densities, and local man-made noise levels.
