1 What s New in the 21st Edition of The ARRL Antenna Book? By R. Dean Straw, N6BV Senior Assistant Technical Editor, ARRL Dayton, May 2007
2 What s New in the 21st Edition of The ARRL Antenna Book? It s hard to imagine that this is the fifth Edition of The ARRL Antenna Book for which I ve been Handling Editor! Goodness, how time flies.
3 Changes in the 21 st Edition About 20% of the book changed materially. The complete printed book is on the CD- ROM bundled with the book, just like the 20 th Edition. Plus there are software programs and data on the CD-ROM.
4 Changes in the 21 st Edition I received tremendous help from the following contributors: Roy Lewallen, W7EL Chap 8, Multielement Arrays Rudy Severns, N6LF -- Chap 27, Measurements
5 Changes Here are some examples of the kind of changes you ll find in the paper book. As usual, you ll find lots of comparisons of antennas thanks to the latest computer modeling software. Here are some highlights from Chapter 6, Low-Frequency Antennas.
6 Chap 6, Low-Frequency Antennas The importance of low angles for low-band DXing.
7 Chap 6, Low-Frequency Antennas NVIS More coverage of NVIS techniques.
8 Chap 6, Low-Frequency Antennas NVIS More coverage of NVIS techniques.
9 Chap 6, Low-Frequency Antennas
10 Chap 6, Low-Frequency Antennas A 40-meter CVD Compact Vertical Dipole.
