Abstract:

High-speed computations were made of the improvement in low-angle vertically polarized radiation obtainable with various sizes and configurations of ground systems, for various frequencies, ground constants, and elevation angles. It was shown that, in general, a ground screen of radius 250 feet produces an improvement of 3 to 9 dB on poor to fair soil conductivity 10 millimhos per meter at frequencies of 8 to 32 Mcs. Improvement is greater with larger ground systems, higher frequencies, poorer soils, and at lower elevation angles. Author
