RADIO SCIENCE FOR THE RADIO AMATEUR

“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.

See order form for SARL member special price

Every chapter of this 22nd Edition has been updated or rewritten to some degree, including entirely new chapters on limited-space antennas, portable and mobile antennas, receiving and direction-finding antennas, building towers, antenna system troubleshooting, and updated listings for antenna system materials and service suppliers. The chapters in this edition have been re-organized to progress from principles through practical applications.

You can build it! Even the novice builder will appreciate the complete construction notes for dozens of antenna designs including wire and loop antennas, verticals, and Yagis. New designs in this edition include a C-pole ground-independent HF antenna, patch and Vivaldi antennas, “cheap” VHF and UHF Yagis, a 40 meter Moxon beam, a TV-to-ham log-periodic conversion, and improved half-element designs for Yagis. The antennas in this edition benefit directly from the latest computer modeling techniques.

Short Antennas for 160 Meter Radio

Compact Antennas Are Possible on Top Band!

160 metres is known to radio amateurs as “top band.” However, 160-metre antennas can be large and difficult to install due to lack of available space.

Short Antennas for 160 Meter Radio dares to discuss the possibility of smaller antennas for this intriguing band. Intended for amateurs with advanced skills in antenna modeling, Grant Bingeman, KM5KG, walks you through the theory behind innovative designs for relatively compact antennas. You’ll learn how to enhance bandwidth, minimize loss, and employ other techniques to enjoy 160 meters with limited real estate.
