ARRL Introduces Book on Selecting, Using Antenna Tuners in Your Station
Antenna tuners are devices often misunderstood in the Amateur Radio world. While not every station requires an antenna tuner to transmit radio signals, without one an incompatibility between the transmitter and the antenna system can result in poor performance. The ARRL Guide to Antenna Tuners: A Radio Amateur’s Guide to Antenna Matching by Joel R. Hallas, W1ZR, will help you understand how to select the right tuner for your needs and how to use it in your shack.
The ARRL Guide to Antenna Tuners discusses the details of the different configurations and requirements of antenna tuners. It explores the design, construction and applications of the different types available. You’ll be able to determine if one is necessary in your station, what type of tuner is needed and where to install it for maximum improvement. This book will give you a better understanding of your antenna system and the way it can be improved through the selection and use of the appropriate antenna tuner.
