It's a bit of a stretch to call it a "book" -- it's a well-written, 
well-documented engineering report on the well-planned and well-executed 
antenna measurements that Steve and Ward did something like 12-15 years 
ago. This report, another on companion tests on HF verticals, and N6BT's 
"Array of Light" book are all available from Steve's Champion Radio 
website, and all are worth far more than what you pay for them.

The N6BT book is really about antenna design, discusses the designs of 
his Force 12 antennas, and includes designs for a nice variety of HF 
antennas. The only thing it lacks is an editor -- several chapters are 
redundant. One of the chapters debunks the inflated gain claims of 
antenna manufacturers, showing that the advertised gain numbers for 
their tri-banders were 3-6 dB greater than the maximum possible gain for 
a monoband Yagi of comparable size.
