Influence of Horizontal Ground Wires on Low Angle Radiation from HF Antennas.

Abstract

Digital computer programs are being developed to evaluate the effects of horizontal ground wire systems on the low angle radiation from vertically polarized HF antennas. An extensive method of moments program (WF-LLL2A) has been modified for this purpose. An alternative approximate method has also been studied and the results compared. Results to date indicate the feasibility of these types of calculations and that a low angle field enhancement of 20 to 25% by design of the ground wire system may be possible at the higher frequencies in the HF band.
