This work adapted some existing empirical electric field strength models that are best suitable for Ekiti State in Nigeria, using ultra high frequency (UHF) signal. A television signal (Broadcasting Service of Ekiti State (BSES)) was used for this work. The propagation models considered are: free space, Hata, ITU-R and ERC Report 68 models. The BSES channel 41 station transmits at a frequency of 631.25 MHz for video signal. The signal levels of the transmitted signal were measured radially along four routes using a digital signal level meter and the corresponding distances were also measured using a global positioning system (GPS). Data processing and computations were carried out and the results show that the modifed free space model gives a better prediction for the electric field strength in Ekiti State with a correction factor of -25.48 and root mean square error of 6.21 dBμV/m.
