Receiving Antennas for the Radio Amateur
Authored by Eric P. Nichols, KL7AJ . Published by ARRL.

Transmitting and receiving antennas have different jobs to do.

Although the fundamental characteristics of antennas apply to both transmission and reception, the requirements and priorities of receiving antennas can be vastly different from those of transmitting antennas. Receiving Antennas for the Radio Amateur focuses entirely on active and passive receiving antennas and their associated circuits. There are relatively few cases where a radio amateur cannot benefit from a separate, well-designed receiving antenna or antenna system. On the low bands, including our new allocations at 630 and 2,200 meters, heavy emphasis on the receiving end of these radio paths is essential for success.

The active antenna holds a prominent position in this book, as it offers good receiving performance while taking up minimal space. Recent developments in radio frequency (RF) semiconductors, especially low-noise RF operational amplifiers, have made a number of previously difficult-to-implement active antenna designs a very simple task.

Exploring the Magic of Wireless Communication!

There are countless ways for radio signals to travel from transmitter to receiver, and understanding how radio waves interact with their environment is an important factor in successful radio communications. While amateurs can maximize station performance and reliability with the right equipment, knowledge and skill, we cannot control propagation. Through scientific exploration and experimentation, we can improve our understanding of propagation and how it affects radio signals.

Propagation and Radio Science presents a comprehensive overview of one of the most fascinating and rewarding activities in Amateur Radio. Author Eric Nichols, KL7AJ, uses his lively, engaging approach to present the complex subject of radio propagation in simple, easy-to-understand terms. This book covers topics ranging from theoretical exploration to practical application. It explains the phenomena we observe on the amateur bands and invites you to embark on the journey through the still-unknown radio propagation universe.

“THIS IS AN EXCITING TIME TO BE INVOLVED IN SCIENCE AND TECHNOLOGY, PERHAPS THE MOST EXCITING IN HISTORY”
-- David Saltzberg, the science consultant for "Big Bang Theory”

You can contribute to big science as a radio amateur! Regardless of your experience and resources, as a ham radio operator you have what it takes to make a meaningful contribution to science and technology. You have a window into the universe not available to most people--as every physical phenomenon, from the galactic to the microscopic, interacts with radio in some manner. Radio Science for the Radio Amateur will lead you to horizons of scientific exploration and discovery.

Radio Science for the Radio Amateur explores and explains the often profound differences between science and technology, and dispels the notion that we know all there is to know about radio. Using a fresh, playful approach, Author Eric Nichols, KL7AJ, will guide you through some of the most fascinating “nooks and crannies” of the radio universe. Along the way, you’ll find out how solving long-standing mysteries of radio, of which there are still many, doesn’t require expensive hardware, but merely a scientific mindset and attention to detail.
