This Publication provides radio amateurs and short-wave listeners with the definitive design guide for sending and receiving radio signals with Antenna Toolkit 2nd edition.Together with the powerful suite of CD software, the reader will have a complete solution for constructing or using an antenna - bar the actual hardware! The software provides a simple Windows-based aid to carrying out the design calculations at the heart of successful antenna design. All the user needs to do is select the antenna type and set the frequency - a much more fun and less error prone method than using a conventional calculator to solve formulas. 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 to the author'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.

Cabling is one of the fastest changing technologies, and Data, Voice and Video Cabling, 3rd Edition, has been updated to address all the latest developments in premises cabling, including technologies and applications in copper, fiber, and wireless cabling. This text is organized to aid in the understanding of cabling, by following a logical format that covers background information on communications systems and media first, and then delves into more detailed discussions on each media type: copper, wireless, and fiber. Separating the key concepts into specific sections also helps to minimize confusion between the unique installation practices among the different technologies. Within each section, topics progress from the basics to components, installation, and testing to assist in the development of individual skills. This book also provides readers with important background and resources regarding the most recent cabling standards, which are an integral part of this fast-paced industry.
