book that does not?

Kraus, _Antennas_
Johnson, _Antenna Engineering Handbook_
Lo and Lee, _Antenna Handbook_
Balanis, _Antenna Theory_
King and Harrison, _Antennas and Waves_
Jordan & Balmain, _Elecromagnetic Waves and Radiating Systems_
King, Mimno, and Wing, _Transmission Lines, Antennas, and Wave Guides_
Brown, Sharpe, Hughes, and Post, _Lines, Waves, and Antennas_
Stutzman & Thiele, _Antenna Theory and Design_

to name a few. I'm sure there are many more, but those are the ones
currently on my shelf.

Several of these authors use an image to analyze a vertical antenna over
a perfectly conducting ground of infinite extent. None use it for any
other situation, including elevated radials. And for a very good reason
-- it's not valid for other situations.
