This book is one of a series designed to help anyone who wants to construct antennas for radio transceivers but who has only a basic knowledge in radiocommunications technology. The approach applied in this book is similar to the do-it-yourself methods of trade books and theories are kept to a minimum. Detailed illustrations are extensively used throughout the whole process of antenna construction to simplify the otherwise difficult to comprehend technical jargon.

The antenna designs presented here are specifically cut to the dimensions necessary for proper operation in 140-150 MHz VHF band. Each chapter deals with a particular design and an extra chapter at the last part is added to help the constructor in converting the given antenna dimensions for other frequencies. However, the formulas for conversion give only a generalized information and much of the fine-tuning of the new dimensions is left to the actual experimentation of the constructor. A highly detailed no-guessing antenna dimensions for other frequency bands are described in other books in this series written by the author
