[TowerTalk] Kraus's book "Antennas" is available for free at archive.org

[Jim Lux]

2nd edition, which is fine for most uses..

One of the best antenna textbooks out there, in my not so humble 
opinion.  Any text which has pictures of the author standing in the 
backyard in front of antennas he/she built is a good one.

It has all the the theory and the math, but is accessible without it, 
and doesn't require you to derive everything from Maxwell's equations to 
understand it.

Anyone building HF antennas, and in particular, using modeling tools, 
needs this book or an equivalent.. Balanis is the other famous text, but 
I find he's a more "start with the theory and see what happens", while 
Kraus is a "here's what happens, let's figure out why" sort of approach.
