VHF/UHF, Trees, guided propagation and canyon effect.
Trees have an important influence on propagation.
Usually, they are considered as obstacles causing
propagation attenuation. Conversely, in this paper we will
demonstrate that trees along road sides contribute to signal
strengthening in what is similar to canyon effect resulting
from propagation in tunnels or street-guided propagation
in urban, to name few examples.
