Most people fail to realize that ON4UN's single elevated radial per 
element 80 meter four square is placed above his 160 meter ground 
plane.  On page 9-40 of "Antennas and Techniques for Low Band DX-ing" 
John writes, "I use quite an extensive radial system, consisting of 
approximately 250 radials ranging from 18 m (60 ft) to 75 m (250 ft) 
in length."  

On page 11-55 ON4UN writes, "While modeling the array, I found that 
the quality of the ground under the array was important to the gain 
as well as front to back ration at low angles."
