VHF and up isn't forgotten with a selection of antennas for microwaves, 2m, 70cm that includes horn, beams and log periodic varieties. Selected from around the amateur radio World and from some of the great names of antenna design there is much here that will inspire 'You to want build! Nichols, KL7AJ Although the fundamental characteristics of antennas apply to both transmission and reception, the requirements and priorities of receiving antennas can be vastly different from those of transmitting antennas. Receiving Antennas for the Radio Amateur focuses entirely on active and passive receiving antennas and their associated circuits.
There are relatively few cases where a radio amateur cannot benefit from a separate, well-designed receiving antenna or antenna system. On the low bands, including our new allocations at and 2, meters, heavy emphasis on the receiving end of these radio paths is essential for success. The active antenna holds a prominent position in Receiving Antennas for the Radio Amateur, as it offers good receiving performance while taking up minimal space.
Recent developments in radio frequency RF semiconductors, especially low-noise RF operational amplifiers, have made a number of previously difficult-to-implement active antenna designs a very simple task. Receiving Antennas for the Radio Amateur is a wide ranging book readers will find chapters covering Preamplifiers, Power Gain, Small loops and a wide array of other antennas.
If you are looking to maximise your receive capabilities, this book provides the ideal guide to this topic and is a must for every radio amateur's bookshelf. Written in a question and answer format the column dispenses practical answers troublesome problems, myth busting and great ideas covering a range of topics. Each question is treated to an answer written an eminently readable form that informs, provokes and stimulates. There are dozens of designs, practical solutions to an array of antenna issues included from the pages of QST.
If you're puzzling over how to improve your station antennas, or solve a problem with your antenna system, chances are someone else has shared the same questions with - and received helpful answers from - The Doctor. International Antennas brings together some of the very best material that has been published in recent years.
International Antennas has an emphasis is on practical rather than theoretical.
The Antenna Theory Book Reviews
You will find descriptions of the construction and performance of antennas enabling the reader to build their own versions. These articles have been written by experienced radio amateurs who have been so pleased with the performance of their particular antenna, that they have been moved to put pen to paper to share this experience. There is a huge range of antennas included in this book, covering 17 bands from VLF through to 70cm.
You will find articles covering the 'stealthy' antennas through to novel approaches to classic antennas. There are verticals, loops, beams and a host of unusual designs. International Antennas is a fabulous collection of antenna articles from around the world. It is intended for everyone who is interested in amateur radio antenna design or is just looking for practical antennas to study and build. Whilst this book provides a US view of what constitutes a small antenna it is still a valuable resource filled with practical advice. For outdoors there are dipoles, inverted Ls, end-fed wires, loops, verticals and temporary antennas for HF.
You will find compact omnidirectional and directional antennas for VHF that you can install anywhere. There are a number of new projects including a "privacy fence" stealth antenna, self-supporting inverted V dipole and the extended double Zepp dipole. This book even provides tips to get you started that include optimising your limited space station, feed lines, SWR, RF amplifiers, operating modes and RF safety. If you think your antenna dreams mean you're effectively off the air - think again ARRL Small Antennas for Small Spaces provides ideas and projects that will get you on the air regardless of where you live!
Zavrel, Jr, W7SX For most radio amateurs who learned basic antenna theory when they studied for licences and may have even have built an antenna or two, the physics of why particular designs work and others don't can be a mystery. Antenna Physics: An Introduction sets out to extend the insight how an antenna works without resorting to degree level texts. Antenna Physics: An Introduction explains many of the underlying principles of antennas and antenna physics and introduces the reader to the mathematics behind these principles.
Written by Robert J. Zavrel, Jr, W7SX, a well-known author and professional antenna engineer this book allows readers to follow along and understand the concepts without needing to solve the complex equations presented. Readers will also find chapters dedicated to Antenna Physics Fundamentals, Radiation of Radio Waves, Dielectric Effects upon Radio Waves, Transmission Lines, Specialised Antenna Configurations, and much more For those who are interested in the how antennas work, the theoretical and mathematical approach that Antenna Physics: An Introduction provides can be of great insight.
Portable operating is gaining popularity in the Amateur Radio community. For amateurs who are unable to install permanent outdoor antennas at home, portable installations are often the only way they can get on the air. There are also amateurs who simply enjoy operating outdoors, in nature. For them, portable antennas are necessities. Readers will find HF Antennas with single and multiband designs for all bands from 80m - 10m. With over thirty antennas included there is a wide choice of easy to build and easy to use antennas for every band.
Masts and other supports are not forgotten and you will find ingenious ideas for getting your portable antenna off the ground and keeping it there. Featuring easily constructed antenna systems, ARRL Portable Antenna Classics offers practical ideas and projects to get you on the air from anywhere. But few have ever considered anything beyond the basic antenna designs - this book tries to set that right with a myriad of 'novel' antenna designs from around the world.
What is a 'novel' antenna anyway? This book does not include designs for standard Yagis, quads, quarter-wave verticals, horizontal loops, delta loops, magnetic loops, off-centre-fed dipoles or any of the more standard antenna designs that are found elsewhere. Although you won't find a standard dipole in this book, you will find the choke dipole; magnetic loops tuned by a variable inductance or a novel home-made capacitor rather than the usual vacuum variable; the 'Super Moxon', which adds a pair of directors to the standard Moxon Rectangle design; an orthoganally steered receive antenna that provides incredible levels of rejection of interfering signals; the home-made 'Wonder Whip' for QRP portable operation; a mobile antenna that can double as a car roof rack and, yes, the original Spiderbeam construction project described by its designer.
This is a major constructional project in which the physical length of the elements are automatically adjusted to provide not just monoband but mono-frequency performance. Originally published in the Radio Society of Great Britain's journal RadCom this is the first time it has appeared in print, in full.
With material included from no less than 57 different authors it shows the ingenuity of radio amateurs around the world knows no bounds. This brand new second edition has been expanded and updated and now provides even more for those with tiny postage stamp-size gardens, intolerant neighbours, planning permission problems or living in apartments. Many amateur radio operators are faced with the fear of interference being caused to televisions, telephones, hi-fi systems and anything with a plug on it.

In these circumstances a stealth antenna may be the solution to allow you to get on the air or even the answer to your planning difficulties. From using house rain gutters and drain pipes, or a magnetic loop in the loft, through to a tuned loop around the window frame Stealth Antennas provides a wide range of ingenious antenna solutions.
Designs include magnetic loops, tuned wire loops, small verticals, zig-zag loaded dipoles and even reviews of a number of commercially-made stealth antennas. Along with new antenna reviews there are two completely new chapters covering Receive Antennas and Top Band Antennas. While easier to conceal because of their small size compared with HF antennas, what are the effects of mounting a VHF antenna in the loft?
Roof tile absorption is discussed, as are the effects of detuning caused by copper water pipes or house wiring. If you are able to put up a ft tower and 6-element beam this book may not be for you.
The Radio Amateur Antenna Handbook
For the rest of us, Stealth Antennas has dozens of original and ingenious ideas for antennas for radio amateurs who might have thought they were radiationally-challenged. Stealth Antennas should persuade anyone with an amateur radio licence that they can work the world without a beam, tower and linear amplifier. Stealth Antennas continues to be the 'must have' antenna book for everyone. This book brings together in a scrapbook format his work from this regular column and a collection of other antenna articles from over the years that have appeared in RadCom.
Antennas Mastered is packed with everything imaginable connected with antennas. Readers will find practical solutions that cover all bands, antenna types, ATUs, Meters, Software and much besides. Peter set out the intention in writing the 'Antennas' column was as he stated "The main purpose of this column is to address problems readers may have installing and adjusting antennas from suburban sites that may be regarded as a challenge; although any antenna subject that is considered to be of interest to readers will be discussed or described".
This has held true over the years and readers will be staggered by the breadth of material covered in over A4 pages of antenna gold. Being a regular columnist Peter also updated and exchanged ideas with readers and discussions were often determined by readers' feedback and questions, making for some fascinating reading. Also contained within the Antennas Mastered pages you will find several standalone articles written for RadCom, the first of these being a method of modelling HF antennas using VHF antennas written in December ; long before computer modelling was available to amateurs.
Organised in the order they were written Antennas Mastered provides a fascinating look at the practical side of antennas and the comprehensive index provided allows the reader to access any specific subject. Peter Dodd, G3LDO has created in his 'Antennas' column one of the best archives of antenna material available and Antennas Mastered provides this for everyone interested in antennas and the practical solutions they need. The arrival of computer based antenna modelling programmes has changed this.
By the time you have finished you should be able to model a whole host of antennas including dipoles, the G5RV, the W3DZZ trapped dipole, verticals, off-centre fed dipoles OCFD , magnetic loop antennas and many more. Computerised antenna modelling for many radio amateurs looks like a black art - needing expensive programs that look like you need a degree in astrophysics to get them to work. This book dispels that provides a straightforward way to design antennas with predictable results. Building antennas can be hard work.
You have to work out what you want to build, source the appropriate copper wire or tubing, measure everything carefully and spend hours putting it all together. There are also over 30 other amateur radio programmes included. This is the third volume of the popular Wire Antenna Classics collection and gathers together the best antenna projects and innovative designs from the ARRL magazine QST from through to Spanning over 10 years this book features more than 40 practical designs for a wide range of wire antennas, from simple projects to more complex.
As you read, you'll discover new ways to experiment with wire antennas and why they are so rewarding to use. Even More Wire Antenna Classics has a wide range of content and you will find details of portable antennas that are both inexpensive and easily constructed antennas systems for operating on the go. There are directional antennas that maximise and focus your signal along with multiband antennas that provide new ways to explore a variety of bands with a single antenna. The efficient and amongst the easiest to build single band antennas are not forgotten and nor are stealth antennas that make the most of space limitations.
From the most complex to the very basic, these antennas have provided radio amateurs with much food for thought and practical designs to build. HF Antennas for Everyone draws on 90 of these RadCom and Radio Communication articles from the last forty years, providing a comprehensive collection of HF antennas, with something for everyone. The selection in this book is a deliberate mix of the traditional and more recent designs. Sub divided into broad sections including horizontal, vertical and loop antennas, there is much variety to be found here. There is however much more than this.
Conventional wisdom of HF antennas says you will need lots of space and money in order to put up suitable aerials. HF Antennas for Everyone shows that no matter the size of the available space you will find antenna designs that will help you get your signals in and out. Feeders are also not forgotten with a section devoted to this fascinating and often overlooked topic. But what if your local regulations prohibit the erection of antennas? That needn't get in your way, because this book even contains a section on Stealth antennas that are either essentially invisible or disguised as something quite different.
It is often said that there is nothing new in aerials, but HF Antennas for Everyone shows this isn't so.
This book demonstrates a considerable number of developments and innovations from the last 20 years in particular, that show designers are starting to find innovative solutions to the age-old problems. Whichever bands you want to work on, whatever the state of the sunspot cycle and however large or small your garden, in HF Antennas for Everyone you'll find an antenna that will get you heard.
Experience the satisfaction and enjoy the benefits of building your own wire antennas. Inside, you'll find more than just creative ideas. Size xmm pages. An ideal book for Field Day planners or the next wire antenna project at your home station. Packed with the very latest wire antenna designs and developments from around the world, it covers a vast array of wire antenna designs including dipoles, doublets, verticals, loops and end-fed wires, as well as subjects such as impedance matching, ATUs, baluns, feeders, antenna masts and rigging and there is even an introductory chapter covering the antenna basics.
Successful Wire Antennas has much more content than its predecessors and many subjects get covered for the first time or in much greater detail than before. There is much more besides and the old favourites have not been forgotten, as we go back to the original words used by Louis Varney, G5RV, to describe his eponymous antenna - as well as providing a 21st century analysis of it.

Successful Wire Antennas even includes many examples of the results of computer modelling of the antenna designs featured. Successful Wire Antennas is of inestimable value to radio amateurs world-wide, whatever their level of experience may be.
Free from any difficult mathematics, this book is a lavishly illustrated guide to building wire antenna systems that will be successful for you! But is it working effi ciently? How can it be improved?
Radio Antenna Engineering
Well-known antenna expert Peter Dodd explains what makes an effective HF antenna, how to build one and how to measure its performance. The book deals with real locations, such as small gardens, apartment blocks, lofts, etc and how to obtain optimum performance within the constraints of your location. The construction of all manner of antennas is described including single and multi-band antennas, with and without the need for an ATU. There are also simple wire antennas, loops alongside beams such as the Quad and Yagi. There are variations on these which use less space.
Feeding, matching and tuning are included as well as how to terminate coaxial cable in a variety of plugs. There is advice on how to check that your antenna is working using a few simple pieces of test equipment. This is quite simply everything you will need to make the best use of your location, and to build a successful HF antenna.
While not every station requires an antenna tuner to transmit radio signals, often the incompatibility between the transmitter and the antenna system results in poor performance. An antenna tuner between them is often the way to obtain efficient operation The ARRL Guide to Antenna Tuners discusses the details of the different configurations and requirements of antenna tuners.
