This book is a college text and engineering reference on antennas. A
pretty thorough theoretical treatment along with practical information
on antenna design.

Apparently the copyright has expired on these books, so they are not
pirated. I actually own a copy of the Kraus book, but it is attractive
to have a copy on my laptop.

The copyright on that edition was renewed in 13 November 1978
(Registration # RE-7-717, original reg# A47618), so it's still in
copyright (until 95 years after publication: year 2045). This isn't
particularly unusual, since it's a standard textbook, and the second
edition didn't come out until 1988, so the publisher would have made
sure the copyright was renewed, even if W8JK didn't.
