TopBand: ground losses

[sears@rell.com]

     A ground mounted 1/4wave vertical with the highly conductive Gumbo 
     soil of North Texas really helps the far field pattern.

Following on from Jim's point, how far out from the base of the vertical 
do you need to go with a method of reducing ground losses? Intuition 
suggests there would be advantages of getting out into the far field, 
probably a half wavelength or so. However, the USAF study on antennas for 
airborne SINGCARS suggested that a vertical over an infinite resistance 
ground gave the best low angle radiation. So maybe a vertical dipole in 
Arizona?
