Contenido: Volume 1 begins with a necessary review of existing quad arrays, ranging from basic 2-element monoband beams to large multi-band designs. Throughout, quads are analyzed using current method-of-moments computer techniques to determine their HF characteristics: the goal is to find the actual bandwidth of basic performance parameters, such as gain, front-to-back ratio, and feedpoint impedance. The analysis attempts to isolate basic properties that affect overall quad performance. As well, various common point and individual element feed systems are analyzed to show their effects on performance. Full dimensions appear for each quad design, along with antenna model descriptions for those wishing to extend the analysis. Each chapter in this 220-page book is fully illustrated with sketches, graphs, and antenna patterns. There are 125 of these illustrations plus over 80 Tables about performance, dimensions, and parameters for modeling exercises.

Contenido: In this second volume, these factors lead to a rethinking of quad design and to some total redesign of monoband quad arrays. Among the factors influencing the rethinking of quad design are these: the relative narrow-band properties of the quad, the critical dependence of quad design on the diameter of its elements, the requirement for more spacing between quad elements to achieve optimal coupling relative to linear elements, the need for elements as thick as those used in Yagis if that quad is to net its theoretical gain advantage over the Yagi, and the relatively rapid rate of change of reactance across the quad operating passband. Volume 2 of this series results in computerized monoband quad design programs for 1 to 4 element arrays, as well as in a consideration of larger designs, narrow-band design, VHF designs, and factors influencing the elevation patterns of quads.
