Radio propagation models play a vital role in designing wireless communication systems. The models are used to estimate the location and number of transmitter stations as well as predict the transmitter coverage area. Different models have been developed in literature to predict radio propagation behavior for wireless communication systems in different operating environments. In this paper, least square regression analysis was employed to develop a versatile propagation model for very high frequency broadcasting radio station in vegetation and/or rocky environment. The developed model was later evaluated by comparing its path loss prediction result with two existing path loss models in literature. The results of the comparative performance analyses show that the two existing models predict highest difference in propagation path loss compared with that from the developed least square regression model. The developed model when compared with the estimated value was found to perform favorably well for each route and the entire coverage area of the transmitter station used as case study. In addition, the result of the study confirms the findings of other researchers that there is no single or universal propagation model that exactly fits all terrains, applications and environments.
