The table 1 shows the statistical data for all the data plotted in Figures 3 and 4. The CGR model provides the best fit to the
experimental measurements data, and closely followed by GR model. The FSA model of radio wave propagation loss, since it is
based on free space communication links (LOS), does not include the additional loss on the propagation components such as
direct wave and reflected, refracted, diffracted waves etc through the complex communication channels like forest, and
therefore, it does not have ability to model forest links accurately. Also, based on the results obtained, SUM(CGR, ITU-R) and
SUM(CGR, Weissberger) models which incorporated the foliage-induced excess loss for the radio-wave propagation through
the forest medium have failed to adequately handle the radio waves propagation loss at VHF band through long forest depth
