The 25th edition of the ARRL Antenna Book is on the shelf now, joining the 22nd edition book I picked up when I was first licensed in 2012.
It’s a pretty big book, and the digital download weighs in at about 1 GB (~1.4 GB uncompressed). About 1GB of that is the supplemental content, software, propagation prediction, and antenna modeling files. By contrast, the CD included with the 22nd edition was just under 650 MB.
Content wise, it’s pretty similar to the 22nd edition with some expanded sections on antenna modeling and propagation. Where this version shines is in all the extra content provided in the digital download. The supplemental files for each chapter alone accounts for about half the size of the digital download (about 770 MB).
The 25th edition goes for the same simple black cover and silver text as the 100th edition ARRL Handbook.
Looks pretty good next to the 2014 Centennial edition and 2023 100th edition of the ARRL Handbooks.
