6.1 Base Drive Voltages

NEC-2 requires the broadcaster to change his starting parameters from field ratios to the voltages present at the drive point of the towers. Although there are several ways to accomplish that, this section describes a modified version of the method given by Trueman in IEEE Transactions on Broadcasting, March 1988. The process, as applied to broadcasting, is explained in the sections that follow.

First, however, a word of encouragement is in order at this point. The sections that follow present some rather laborious and boring mathematics. They develop the procedure for calculating the drive point voltages that create ...
