摘要：
Propagation studies conducted in India are reported. The attenuation measurements were made in the frequency range of 50-800 MHz and distances from 40 m to 4 km. Both horizontal and vertical polarisations were used. The results on the nature and magnitude of the attenuation caused by the presence of vegetation are presented. They support the theory of lateral-wave mode of propagation of radio waves in jungle environment. These results have been compared with those of sub-tropical pine forest.
