Book Synopsis VHF and UHF Antennas by : R. A. Burberry
Download or read book VHF and UHF Antennas written by R. A. Burberry and published by IET. This book was released on 1992 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: The purpose of this program is to design, build, test and deliver a VHF-UHF fixed station mast mounted antenna system. Antenna Products proposed three configurations to investigate in an effort to achieve an acceptable system. Configuration A consisted of combining a VHF monopole/counterpoise antenna and a UHF collinear antenna. During the investigation it was found that the counterpoise did not properly terminate the radiating structure when the radials are less than a quarter wavelength long. The performance is characterized by a loss of gain at the lower frequencies. A full size structure would be larger and heavier than a dipole antenna. Therefore, no further investigation of configuration was undertaken. Configuration B consists of combining a VHF vertical half-rhombic antenna system and a UHF collinear antenna. The rhombic antenna system was envisioned as two rhombic curtains mounted orthogonally about a 10 meter mast and would serve as guys for the mast. The UHF antenna would mount on top of the mast. It has been determined that to achieve reasonably omnidirectional azimuth patterns it is necessary to use four rhombic curtains in an azimuth array. At the interim report, the height of the antenna was 10 meters and the radius was 25 meters. Further investigations have lead to a 10 meter tall structure with 10 meter radius that uses six equally spaced slant wires that are fed in-phase near ground and connected at the top of the tower. A UHF collinear dipole array mounts on top of the dielectric mast. A prototype of this antenna is available for shipment to CECOM for further evaluation. The propagation mode for this antenna is surfacewave instead of spacewave as commonly experienced when two antennas are mounted on masts above the earth's surface. Therefore, field tests should be conducted to determine the suitability of the antenna for the application.

Book Synopsis Amateur Radio HF Antennas by : Claude Jollet
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.

Available in PDF, EPUB and Kindle. Book excerpt: As a result of a 10-month study funded by the Air Force Space and Missile Systems Organization and carries out by ESSA's Institute for Telecommunication Sciences, four UHF antennas were designed and their gains versus elevation angle up to 45° and horizontal plane patterns for a 5°elevation angle were measured with each antenna buried beneath 1 m of refractory concrete. Techniques were developed and used to measure loss tangent and dielectric constant of plane ground and large samples of refractory concrete versus drying time and temperature. Theoretical studies of buried annular slots, buried antenna patterns, encapsulant geometry, and dielectric-coated linear antennas paralleled the measurement effort.
