Available in PDF, EPUB and Kindle. Book excerpt: Your how-to guide to become a ham Ham radio, or amateur radio, is a way to talk with people around the world in real-time, or to send email without any sort of internet connection. It provides a way to keep in touch with friends and family, whether they are across town or across the country. It is also a very important emergency communication system. When cell phones, landlines, the internet, and other systems are down or overloaded, Amateur Radio still gets the message through. Radio amateurs, often called "hams," enjoy radio technology as a hobby, but are often called upon to provide vital service when regular communications systems fail. Ham Radio For Dummies is your guide to everything there is to know about ham radio. Plus, this updated edition provides new and additional information on digital mode operating, as well as use of amateur radio in student science and new operating events. • Set up your radio station • Design your ham shack • Provide support in emergencies and communicate with other hams • Study for the licensing exam and choose your call sign If you're looking to join a college radio club or just want to learn the latest tips and tricks, this book is a helpful reference guide to beginners, or those who have been "hams" for years.

The new edition has been revised to include further cases of propagation, additional antennas and also two new chapters - Small Loop Antennas (a topic of considerable interest, which has been the subject of much recent debate in the amateur radio press); and Yagi Beam Antennas (widely used at HF and VHF). The CD software has also been updated.Joe Carr's expertise in the area of antenna design is legendary. Antenna designers, whether hobbyist or technician, can be assured they need look no further than Antenna Toolkit for the complete guide to understanding the practicalities of using and designing antennas today.A complete solution for antenna design in one package.Includes free CD-ROM with state of the art software for all design calculations.The definitive guide to antenna design for radio amateurs and short-wave listeners.

Available in PDF, EPUB and Kindle. Book excerpt: THE DEFINITIVE ANTENNA REFERENCE--FULLY REVISED AND EXPANDED! Design and build your own antennas with the help of this unique guide. Updated and revised to provide clear answers to questions frequently asked by hobbyists and electronics technicians, Practical Antenna Handbook, Fifth Edition blends theoretical concepts with hands-on experience--requiring only high school mathematics Reorganized to flow logically from broad physical principles to specific antenna design and construction techniques, the book begins by covering the fundamentals. Then the half-wave dipole is discussed both as an excellent antenna in its own right and as a conceptual tool for predicting the performance of other designs. Transmission line impedance matching techniques--and a companion Smith chart tutorial--lead into "must have" accessories for tuning, monitoring, and troubleshooting antenna system performance. Other tools, such as antenna modeling software and network analyzer add-ons for PCs and Macs, are addressed, and concluding chapters offer fresh insights into support structures and installation techniques. NEW TOPICS COVERED INCLUDE: Characteristics of all-driven and parasitic arrays Beverages and small MF/HF receiving loops Top-loaded shunt-fed towers and other verticals Theory and design of Yagi beams Effect of real ground on propagation and antenna patterns, impedance, and efficiency Lightning protection and four kinds of ground systems Zoning and restrictive covenants COVERS A WIDE VARIETY OF ANTENNAS: Dipoles and inverted-Vs Quads, delta, and NVIS loops Wire arrays (bobtail curtain, half-square, rhombic) Verticals and shunt-fed towers Rotatable Yagi beams MF/HF receiving antennas (flag, pennant, K9AY, Beverage) Mobile and portable antennas VHF/UHF/microwave antennas And many more GO TO WWW.MHPROFESSIONAL.COM/CARR5 FOR: * Tables of worldwide geographic coordinates and antenna dimensions vs. frequency * Supplier updates * Author's blog * Additional photographs and schematics * Links to tutorials and specialized calculators

Download or read book Amateur Radio HF Antennas written by Claude Jollet and published by Claude Jollet. This book was released on with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Poynting Vector Antenna written by Ted Hart and published by Bookbaby. This book was released on 2016-08-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Poynting Theorem states that radiation is a product of the Electric (E) and Magnetic (H) fields of an antenna. The fields must occur simultaneously and have the proper curvature. This is accomplished in the Poynting antenna. A conceptual antenna has two hollow cylinders. A tuning coil resonates with the capacity between the two cylinders, thus developing a high voltage between the cylinders which creates the E field. The cylinders are very short with applied voltage on one end and open on the other. This allows RF current to flow on the cylinder which creates the H field. The two fields are in time phase and are orthogonal, thus satisfying the Poynting Theorem. The shape of the antenna may vary from two flat plates to a Flute configuration, and virtually any shape between. The significance of the Flute is that the shape follows a cosine function allowing both fields to be active along the length of the antenna. The Flute antenna may be tuned (simply by varying the inductance of the tuning coil) over a wide range. One of these has a total length of four (4) feet and may be tuned from 2.5 to 25 MHz with high efficiency (loss of less than 1 dB at the lowest frequency). The +/- 3 dB bandwidth is nominally one tenth (0.1) the operating frequency. Thus Q=10. The radiation pattern is isotropic and the polarization is elliptical. This virtually eliminates fading due to Faraday rotation for HF communications, and at VHF frequencies prevents nulls due to multiple reflections from large buildings. The optimum size of the antenna is typically 3% of a wavelength, but may be less if wide bandwidth is not a design criterion. Because the radiation pattern is isotropic and radiation occurs at the antenna, two (2) or more Poynting Vector antennas may be used to form a directional array while the individual antennas are not affected by mutual coupling of the H fields. The text of the book presents new physics concepts including a mathematical description of Radiation Resistance and suggested changes to Maxwell's Equations. The book will be useful to every Ham operator, all Antenna Engineers, and every person concerned with Physics. Because this is a paradigm shift in antenna technology, the book is an excellent text for a graduate level antenna course.
