Abstract

Computer modeling studies indicate that an elevated vertical monopole antenna with four elevated horizontal radials produces more ground-wave field strength than does a conventional ground-mounted monopole with 120 buried radials. For the analysis, the length of the radials and the height of the monopole were set equal to 0.25 free-space wavelength, and the frequency of operation was fixed at 1.0 MHz. Three different sets of ground constants were used, simulating “average”, “very good”, and “very bad” soil electrical parameters. The computer code used for this work was NEC-GS, a “Method of Moments” program which was developed at Lawrence Livermore National Laboratory.
