ARRL publishes a handful of titles that occupy the pinnacle in ham radio publishing, including their license manuals, Operating Manual, Handbook, and, of course, the Antenna book. There is nothing that really compares to ARRL's antenna book in terms of either raw coverage or quality. While there are engineering texts and a ham radio titles that dive far deeper on narrow topics, the ARRL Antenna book covers a vast range of antenna types and topics - and in more detail than the majority of hams will ever care to absorb. This book can be read for its more advanced technical content or, alternatively, be used quite effectively as a project book. I don't often see this book discounted. I couldn't find it new at a discount at the last hamfest I attended, for example, nor is it discounted at my local (unnamed) ham radio store. Couple that with free shipping from Amazon, and it's a deal!
