ABSTRACT
Propagation models are very important tools deployed in planning a radio communication system like the television system. The paper presents the testing of the renowned Egli radio propagation model for television planning in the Very High Frequency (VHF) band for the south- south region of Nigeria. The work was carried out in Edo state through extensive signal strength measurement across selected routes. A handheld spectrum analyzer Sefram 7806 was set to the transmission frequency of the television station used for the investigation and signal strength values were collected at varying distances from the television station. A handheld global positioning Garmin 78CS GPS receiver was used to obtain the geospatial co-ordinates of points were signal strength values were recorded. The results showed that the Egli propagation model cannot be relied upon in the radio planning of future television system in the region due to the huge root mean error value (RMSE) between the pathloss prediction from the model and that obtained from the actual measurements.
