This review is from: Yagi Antenna Design (Radio amateur's library) (Hardcover)

This is actually a compilation of articles written for "Ham Radio" in the 80's by James L. Lawson, W2PV. It is a very thorough walkthrough, starting from deriving equations for mutual and self impedance of parasitic elements in chapter 1 and going on through simple antennas, performance optimizations, loop antennas, the effects of ground, stacking, and several practical designs, including those for 7,14,21, and 28 MHz. As the editor, Bill Myers puts it, "the very large ratio of figures and tables to text has made the logical presentation of this material exceptionally challenging." There are lots of polar plots and tables for gain and front to back ratio. There are plenty of formulas with experimental verification/validation included. Feedpoint resistance/reactance is mentioned, but there aren't too many details in manipulating the resistance, partly because the author feels that discussion is trivial and because it is only valid at single operating point. The computer modeling methodology is somewhat dated and broad band yagis are barely touched on. Other than that, this book is the best I've found on Yagis. With this book, you can reverse-calculate all the assumptions that the other guys made when they wrote their books. Not perfect, but still 5 stars.
