The 100th edition of The ARRL Handbook for Radio Communications



Handbook 100 is by far the most extensively revised and expanded edition in recent years - including new and revised topics, content, and projects. It is written by radio amateurs who share their experience, learning, and discovery from across the state-of-the-art and emerging technologies. Each chapter is authored and edited by experts in the subject.



The ARRL Handbook strikes the perfect balance between comprehensive RF engineering reference and practical treatment of basic electronic fundamentals, circuit design and equipment construction, antennas, transmission lines, safe electrical, RF practices, and more.

Each chapter is filled with the most up-to-date knowledge representative of the wide and ever-expanding range of interests among radio amateurs. There are practical, hands-on projects for all skill levels - from simple accessories and small power supplies to legal-limit amplifiers and high-gain antennas.
