If installed over salty marsh.
Ever tried to model or compare any vertical over average and "perfect" sea 
ground and see the gain at LOW angles?

The higher and larger the current carrying portion of the radiator, the further 
out it is "looking" for (good) ground.

Example of well working vertical installation is at 
http://www.teslaradio.org/w8lrl.htm
"wasting" 360 radials 200 ft long. 

Most studies have addressed the quarter wave or shorter verticals and their 
radial fields, but situation is different with longer verticals and more 
extensive radial fields (morfing into perfect ground).
