INTRODUCTION
Antenna systems have been analyzed and designed using computer simulation for many years by academics and those designing antennas for the military. By comparison to electromagnetic simulation of aircraft and ship structures, modeling medium wave antenna systems is an almost trivial exercise. It has been the experience of this writer and other consultants that a relatively short time spent modeling an AM array can save a great deal of trial and error time tuning up a directional array (DA). FM and television antennas can also be modeled using moment method programs for analysis of the ...
