That W1DX article appeared in QST three times, November 1991, April 1977, and March 1956. There is a lot of misinformation about transmission lines/SWR in the amateur community and I suspect ARRL feels it is worthwhile to republish the article once in a while. There are several excellent books about the subject available that can clear things up. I highly recommend the ARRL publication "Another Look At Reflections" by the late Walter Maxwell, W2DU. Although he puts on the afterburners once in a while, his information appears to be correct - and a real eye opener for someone who has misinterpreted transmission line theory.
