Topband: Anyone purchased the ARRL book on Short Antennas for160???

"Such characteristics would apply to the use of elevated radial systems by 
ham radio operators as well as they do for AM broadcast stations."

Just to note that several installations of new AM broadcast antenna systems 
using elevated radials have been installed at sites where rocky earth 
prevented the use of ANY buried radials, and none ever were installed.

Even though earth conductivity at / near those sites was very poor, the 
radiation efficiencies of those antenna systems were very close to those of 
perfect monopoles over a perfect ground plane.
