Antenna analyzers are arguably one of the most important pieces of equipment in an Amateur Radio station. Designed to measure impedance or standing wave ratio (SWR), the properly used antenna analyzer determines the details of an antenna?s tuning characteristics and helps maximize its performance. Even the simplest antennas can benefit from using one, and your success on the air may depend on it, but only if you understand and avoid the common pitfalls.
Understanding Your Antenna Analyzer is an introduction to the various types of analyzers available, their component parts, how they operate and how to utilize them to get the best possible data. It discusses how to adjust your antenna, enhance your antenna analyzer and the ways certain analyzers can be used as general purpose test instruments in an Amateur Radio lab. Includes product review testing and an in depth look at representative antenna analyzers available today.
