ncrease your station’s receive performance with new book Receiving Antennas for the Radio Amateur by ARRL author Eric P. Nichols, KL7AJ.
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.
Receiving Antennas for Radio Amateurs is available from the ARRL Store or your ARRL Dealer. (ARRL Item no. 0789), ISBN: 978-1-62595-078-9, $27.95 retail, special ARRL Member Price $24.95). Call (860) 594-0355 or, toll-free in the US, (888) 277-5289. It will soon be available for the Amazon Kindle.
