Abstract : Ground-to-ground path loss measurements are tabulated and discussed for paths terminated in surface and buried antennas, with and without security fences. Both horizontally and vertically polarized antennas at 415.9 MHz were used. Path lengths varied from 15 m to 17 km, and depths ranged from 0 to -2.25m. Conical pits 3 m deep were dug into the earth and filled with fuel oil, which served as a homogeneous dielectric surrounding the antennas and formed a smooth, level boundary layer at the surface. Data showing the effect of off-path, terrain reflections on transmission loss between low antennas are presented. (Author)
