73 Vertical Beam and Triangle Antennas by Edward M. Noll

73 Vertical, Beam, and Triangle Antennas by Edward M. Noll (160 pages). This is a fantastic book that covers all aspect of building your own antenna setup. From the Preface: An often-heard comment of the present is: “The days of amateurs building and operating their own equipment are a thing of the past.” To a great extent this is true, since the advent of sophisticated single-sideband equipment has convinced many hams that construction of their own gear is no longer practical. The one big exception to this is in the field of antennas. The amateur, at very little expense and without the requirement of an R&D laboratory, can indulge in experimentation with antennas, sometimes with startling results. 73 Vertical, Beam and Triangle Antennas is the second of a series of books which can make the hobby of amateur radio more than an operational spectator activity. Each antenna described in this book was constructed by the author without assistance. A minimum of tools and equipment were used. You can do the same and use the world as your testing ground. Many of the antennas described in this book compete with, and sometimes surpass, the performance of commercial beams. A number of new approaches in the construction of basic antenna types are detailed. The book is not so much a rehash of common antennas and basic theory as it is a coverage of new approaches and ideas not often used by the amateur. There are 73 individual vertical and beam antennas included in an order that begins with simple construction and progresses in a sequential manner to more complex arrangements. However, if you are interested in only one particular type, you can locate that type immediately and proceed with its erection. 73 Vertical, Beam, and Triangle Antennas is an invitation to some inexpensive education and fun. You will find it very educational and satisfying to put up an antenna that you have calculated, erected, and tuned. You have also gained a conversation peak that can bring you that much nearer to other radio amateurs all over the world. There are very few of them who are not interested in antennas.
