In most cases, they will have higher performance than conventional magnetic flux-coupled transformers. We would swap them in and out as necessary. In a perfect world, we would have 3 different baluns, one for 160/80, one for 40/30 and one for 20-10m. Readers are encouraged to look beyond the design examples to learn the basic theory that makes transmission line transformers different. A GENERAL PURPOSE TUNER BALUN: The selection of components for your tuner balun will depend on the required bands it must cover as well as the power level it must handle. The new edition contains all the valuable information from earlier editions: the classic techniques of Guanella and Ruthroff as well as hundreds of real transformers constructed and measured to establish the practical levels of bandwidth and loss performance. Im looking for something to balance the feed from whatever rg6 random wire I might be trying or a good 'go-to' balun when nothing else is around, if one exists. Understanding, Building, and Using Baluns and Ununs: ISBN 9780943016245 (978-0-94) Softcover, CQ Communications, Inc.
