Computational economies in the prediction of characteristics of HF ` long-wire ´ antennas mounted on large aircraft

This paper examines the consequences for calculations of near-field (antenna reactance) and far-field (antenna resistance and radiation patterns) dependent parameters of an installed `long-wire´ antenna of removing the wings from a mathematical model of a medium-sized passenger aircraft. In the context of calculating link budgets, it is considered that the absence of the wings is not likely to perturb these properties to an extent which is of great practical importance and that neglect of this part of the airframe may be a useful way of making the solution of problems involving larger aircraft with a similar antenna installation both tractable and affordable
