ARRL introduces book on selecting and using antenna tuners

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.
