Abstract :The work presented  is aimed at studying the comparative error bound of Hata and Egli radio pathloss prediction model to determine which of the model will better suit television planning in the UHF band  of Edo state. Signal strength measurement campaign of selected television stations  in the Ultra high frequency UHF band in Benin City was conducted across some selected routes using a hand held spectrum analyzer. The results revealed that for all scenario, both the Egli and Hata pathloss models  could not be relied on for effective radio planning in the region as  both models exceeded the root mean square error  RMSE of 6-7 dB acceptable for the adoption of existing radio propagation models for the  planning of new radio communication systems. However the Hata pathloss model prediction gave a better fit  to the measured pathloss
