Abstract :
A theory accounting for attenuation caused by tree cover for line-of-sight propagation paths at VHF using vertical polarization is presented. An approach to implementing this theory using a terrainsensitive GTD propagation model is also given. Comparisons of model predictions and airborne measurements show that the approach is valid.
