This research work on the determination of pathloss model for ultra‐high‐frequency (UHF) television transmission in the city of Onitsha, Anambra state, was carried out along Niksi Road, 33 area, Nkwelle‐Ezunaka to Nkwelle junction. The latitude and longitude parts of the data were measured using a software “GPS Map Mobile” installed on Tecno W3 android phone. The received power was measured at each point using “B&K precision RF signal strength analyzer 2.0‐GHz 2640.” From the analysis made using the root mean square error (RMSE), and also the graphs were plotted using MatLab package; it was discovered that the measured pathloss was interwoven with established Hata and COST‐231 Hata models by RMSE values of 4.90 and 4.74, respectively, which are within the acceptable range of 0–6 dB. These models are therefore suitable for urban center of Onitsha, and they are useful for prediction of transmission coverage in the city.

尼日利亚阿南布拉州奥尼查的超高频电视传输路径损耗模型的确定

这项关于确定Anambra州Onitsha市超高频（UHF）电视传输路径损耗模型的研究工作是沿着Nkwelle-Ezunaka至Nkwelle交界处33区的Niksi Road进行的。数据的纬度和经度部分是使用安装在Tecno W3安卓手机上的“ GPS Map Mobile”软件进行测量的。使用“ B＆K精密RF信号强度分析仪2.0-GHz 2640”在每个点测量接收到的功率。根据使用均方根误差（RMSE）进行的分析，并使用MatLab软件包绘制图表；结果发现，测得的路径损耗与建立的Hata和COST-231 Hata模型交织在一起，其RMSE值分别为4.90和4.74，均在0-6 dB的可接受范围内。
