HF EXTENDED GROUND SYSTEMS: RESULTS OF A NUMERICAL ANALYSIS.
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 Mc/s. Improvement is greater with larger ground systems, higher frequencies, poorer soils, and at lower elevation angles. (Author)
