A MATCHING PRINCIPLE The first approach was to make use of a principle described by the writer in Amateur Radio, December 1985. Referring to Figure 1, a network is made up in two sections, an antenna phasing section which cancels any antenna reactive component and an impedance matching section (often called an L match) which transforms the remaining
An antenna tuner. Yes, a balanced tuner is optimal, but with the right balun the typical unbalanced T-match tuner will work just fine, as long as the antenna side impedance is high, not low where T-tuners become very inefficient. ...
