On the surface this seems to agree with what I find. There are dozens of
ways to have about the same results. I wonder what Grant has in the book?
I recently purchased a copy from the ARRL and it's well worth the $20 price.
Table of Contents:
- Short Antenna Behavior
- A Better Way to Define Antenna Bandwidth
- Why Top-loading Can Improve Short Antenna Performance
- Top Hat Arrangements
- Inverted Cone Antennas
- Closed Antennas
- Antennas with Two Driven Elements
- T-shaped Antennas
- Inverted L-shaped Antennas
- Antennas with Four Driven Elements
- Spiral Antennas
- Small Horizontal Antennas
- Quadrature Feed Arrangements

While looking for something entirely different, I came across this. I
wonder if anyone has this book?
Grant, KM5KG, is one of the most experienced broadcast engineers around.
http://www.km5kg.com/160meter.htm
Grant claims:
"A New Book from Grant Bingeman, KM5KG
112 pages 8.5 by 11 inches
This book presents 30 practical wire antenna designs that fit inside a 40
by 40 by 30 foot tall space, including the ground system. This report is
specially written for the ham radio operator who lives on a typical
quarter acre lot and has to maintain a practical budget.
E field radiation efficiencies of 75 percent are possible over a very
limited ground system of 18 buried radial wires only 20 feet long."
