A new and systems oriented method of directional antenna tuning

The AM antenna tuning method presented takes into account and absorbs stray inductances and capacitances, and mutual coupling between components with very high initial adjustment accuracy. Besides an antenna monitor and a field strength meter, the equipment used for tuning consists of a high-precision reflectometer, a spring-loaded and side-handled split toroidal clamp-on ammeter, and a Hewlett-Packard HP-15 programmable calculator programmed with routines used to analyze measured raw data. These programs are written to determine power distribution, transmission line matching conditions and phase shifts. The techniques described inherently minimize the number of different ground points one must refer to. In addition, the few grounds needed with these techniques are much closer to true ground.<
