Link-Coupled Antenna Tuners: A Tutorial

L. B. Cebik, W4RNL

In recent editions of various amateur radio handbooks in English, information on inductively coupled (link-coupled) antenna tuners has decreased just to the degree that data on unbalanced network tuners has increased. We may be passing a certain critical threshold below which the information is insufficient for a good understanding of inductively coupled circuits. In response to a number of requests, I have pulled together materials from some older sources (from the 1940s through the 1970s) to make available a more complete and hopefully more cohesive account of link- coupling. The account might be made even more complete, but at the risk of making it excessively obscure. As with every tutorial, one draws a line and takes a risk that enough has been shown to aid understanding without breeding misunderstanding from what has not been said.
