The definitive antenna reference-thoroughly revised and expanded to cover the latest technologies!This fully updated handbook lays out complex antenna fundamentals in simple terms for ham and short wave radio hobbyists and electronics technicians. The book begins with quick explanations of present day antenna theories and practices before providing start-to-finish instruction on the fabrication and installation of real antennas. You will explore every type of antenna system-from VHF/UHF to mobile/wireless and everything in between.Practical Antenna Handbook, Sixth Edition bridges the gap between the highly theoretical mathematics of antenna engineers and the "hands-on" focus of radio amateurs and experimenters. The book covers key areas such as multiple antenna families, inexpensive or free software modeling tools, and "near-professional" network analyzers. You will get coverage of new antenna types for low-frequency applications only now being opened to radio amateurs.Contains everything hobbyists and technicians need to know about antennasBlends theoretical concepts with hands-on experience-requires only high school mathWritten by an electrical engineer and amateur radio enthusiast

Strategic Guide to help prepare for Armageddon, Natural Disasters, Nuclear Strikes, the Apocalypse, and Every Other Threat to Human Life on Earth It seems many people are in denial about the potential difficulties that lie ahead for us and how those difficulties (and potential disasters) might impact them. Some people believe that life will continue on as it always has, or in the event of a disaster, the Government will come to the rescue. Others just prefer to live in denial and ignore the signs that are pointing to serious challenges ahead.

Teaches readers the basics of performing the tests and measurements used in radio-frequency systems installation, proof of performance, maintenance, and troubleshooting. This work examines the instruments used in the various types of measurement before moving on to specific measurement methods.

Intended for technicians and hands-on practitioners, this title features illustrations, and contains information on cutting-edge receiver equipment as well as the most popular types used in a variety of markets.

A hands-on guide to finding the sources of electromagnetic interference and then fixing the problems. It includes basic theory of EMI as well as explanations of why this problem is becoming more serious as the international scope of the communications and electronics industries grow.

Fully revised and updated, the fifth edition of this classic antenna resource includes new information on wireless devices, radio frequency interference (RFI), and the latest antenna modeling software.
