Abstract: This paper presents the prediction of signal attenuation Digital Terrestrial Television (DTTV) in Port Harcourt, Rivers State, Nigeria A signal Tracker (WS6916), Micronix Global Positioning System (GSP) module alongside a drive test was used to carry out the research work at Star times office, Olu-Obasanjo Road. The Power Density change with the varying distance between the receiver and the transmitter (Nobe B). For a more concise measurement, readings were taken between April and August 2019 (wet season) at different times of the day. The path loss exponent (n) of 4.7 reveals that Olu-Obasanjo road is an urban area. As the location changed, the path loss exponent (n) increased to 15.4, revealing the interference of tall buildings, and other forms of obstruction. The exponential shape of the graph shows a decaying signal along the distance axis with distance, expatiating that the inverse relationship between powers received (dbm) and distance (km). Attenuation was observed to have increased while increasing the distance between the transmitter and receiver. The results obtained were analyzed using the log-distance empirical model to obtain both the parameters of Path loss exponent and the Mean Square Error (MSE).
