Sinusoidal Current Distribution
Since the earliest days of radio, analysis of the vertical radiators and directional arrays of AM radio stations has made use of assumed current distribution for each tower. For the sake of simplicity, uniformity and convenience, sinusoidal current distribution was assumed. This simplified the mathematical integration of current along the length of each radiator for calculating its radiation characteristics. The reality is that this wasn’t a bad assumption—it was the best we had to work with. But out in the real world, and especially when dealing with a multi-tower directional array, top loading ...
