After describing the typical configuration of the ground-plane range in this chapter, we discuss the main feature influencing its design and operation: the ground itself. We resort to idealizations of the ground plane using omnidirectional antennas at first, but then we become a bit more realistic by investigating the effects of directive antennas and imperfectly conducting soils. At the end of the chapter we analyze two methods of defeating the ground plane, both of which have been abandoned in practice, even though the analysis suggests that one may be reasonably effective.
