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.
