ABSTRACT

This work exhibits the performance of path loss models for low band very high frequency (VHF) in urban and rural environment by juxtaposing path loss models such as: Egli, free space, Hata Okumura, CCIR and Cost 231 Hata models using MATLAB. The path loss value changes while varying the frequency, antenna height over path distance. Reviewing the simulation, Hata Okumura and CCIR models outperforms in the urban environment while CCIR and Free Space models surpasses in the rural environment. Making CCIR model suitable for both environments. This study examines the viability of forecasting signal losses for low band very high frequency (VHF).

Keywords: Path loss, Very High Frequency (VHF), Transmission antenna height (TAH), Reception antenna height (RAH)
