Path loss models are essential in the planning of wireless networks. However, peculiar ambient characteristics geographical locations necessitate a wide range these to take into consideration different terrain dielectric, scattering irregularities, and clutter. This study investigates effects clutter on frequency‐dependent path very high frequency (VHF) ultra (UHF) bands using multi‐transmitter scenarios. Seven transmitters 15 measurement routes were covered an Agilent N9342C spectrum analyser. The measured results show that models' prediction errors (PEs) follow profile also noticeable along each route with varying degrees impact. Near constant standard deviation (SDEs) observed across all for specific as well strong dependency clutters routes. UHF VHF have average SDEs 10.5 7.5 dB, respectively. A three‐dimensional digital elevation model (DEM) showing PE was developed. Contour lines extracted from advanced spaceborne thermal emission radiometer global DEM data sets. Visualisation achieved ArcScene software environment.
