Book Description
The contents of this book are mostly aimed at the amateur radio beginner and aspiring ones. Therefore, this book provides answers to basic questions like: What is the best HF antenna for my needs and location? What type of stand-alone antenna tuner should I use and which should I avoid? How can I hide my HF antenna from the neighbors and still get acceptable performance from it? What about lightning protection? This book will supply immediately useful answers to the above questions and many more. A properly designed and installed amateur radio HF antenna system can potentially make the humblest ham radio equipment perform like stations worth thousands of dollars. We are confident that the antenna experimenter will find the information given here priceless. Furthermore, any ham radio operator, armed with the information this book contains, will become a much better informed buyer of commercially made HF antenna systems and accessories. This special compendium edition is published in response to ham radio operators who wrote to ask that all the basic information, on and related to amateur radio HF antennas, be made available in one book instead of four, arguing that it would be more convenient. The author and publisher agree. Therefore this edition contains the complete four-book series on Amateur Radio HF Antennas published by Claude Jollet, VE2DPE.

Book Description
Reflecting a growing interest in phased array antenna systems, stemming from radar, radio astronomy, mobile communications and satellite broadcasting, Array and Phased Array Antenna Basics introduces the principles of array and phased array antennas. Packed with first-hand practical experience and worked-out examples, this is a valuable learning tool and reference source for those wishing to improve their understanding of basic array antenna systems without relying heavily on a thorough knowledge of electromagnetics or antenna theory. Features a general introduction to antennas and explains the array antenna principle through discussion of the physical characteristics rather than the theory Explores topics often not covered in antenna textbooks, such as active element pattern, array feeding, means of phase changing, array antenna characterisation, sequential rotation techniques and reactively loaded arrays Guides the reader through the necessary mathematics, allowing them to move onto specialist books on array and phased array antennas with a greater understanding of the topic Supported by a companion website on which instructors and lecturers can find electronic versions of the figures An ideal introduction for those without a background in antennas, this clear, concise volume will appeal to technicians, researchers and managers working in academia, government, telecommunications and radio astronomy. It will also be a valuable resource for professionals and postgraduates with some antenna knowledge.

Book Description
Describes the VHF and UHF antennas for the 30-3000 Mhz range that have been developed over the past 50 years, including many designs that have not previously been treated in detail, and several new uses for old designs. Among the topics are methods of predicting and measuring the performance of antennas, and how it is affected by the local environment, both normal and adverse, and by the structures on which the antennas are mounted, both fixed and mobile (including humans). Addressed primarily to practicing antenna engineers; the basic theory is assumed to be known except for the less known types. Distributed by INSPEC.

Book Description
“Super-Dipole Antennas” is a book that introduces a completely new “Unified Broad-Banding Method”. This method primarily consists of the use of a 1/2 wavelength Dipole, which is fed with a 1/4 (or shorter) wavelength resonant line. The amount of coupling between these two components is greatly reduced and controlled to produce a wide SWR bandwidth. This Broad-Banding Method is referred to as “Critically-Coupled Broad-Banding”. There are many different configurations that are possible and these are presented in a logical sequence, showing how each has evolved from the previous one. Some use “Low Impedance Coupling”, while others utilize “High Impedance” and both can achieve low SWR bandwidths. Most all of the configurations are adaptable to the various radio Amateur bands, from 160m to above the 6m band. Some utilize wire radiators, while others at the higher frequencies, utilize aluminum tubing. Large numbers of antennas are presented covering most all of the wider Amateur radio bands where Broad-Banding is most desirable. The completely new and unique configurations introduced will completely change the perception of how antennas are Matched and Broad-Banded. Many of the configurations are very simple and easy to understand. Most have been reduced in complexity, cost of materials, and can readily be assembled and these are referred to as “Super-Dipole Antennas”. Other methods of Broad-Banding are also presented, which have unique advantages, while some others have Multi-Band capabilities. Almost all of the configurations presented include charts showing how the Far-field gains and coaxial losses vary across each of the bandwidths, giving a good perception of the efficiency on each band. Each antenna configuration has been carefully computer-modeled, making certain that all of the critical requirements are taken into account and checking the consistency of results, thus giving an assurance of good modeling accuracy. This book has been written to purposely keep it simple, point out the pertinent details, make comparisons between different antennas, in the simple straightforward manner, while avoiding any complicated formulas. It is meant to be a tutorial on Broad-Banding, along with the catalog of practical antenna configurations in order to encourage further interest, imagination and experimentation.
