Actually, I was told this by W8JI. It's in the TowerTalk archives 
somewhere (See: <http://www.contesting.com>)

I just spent some time in the archives. I can't find the article I 
remember reading, but I did find this excellent summary: 
<http://lists.contesting.com/_topband/1996-October/012621.html>

Take note of the actual experiments W8JI (his call is listed as W8JIT for 
some reason) did with both elevated and ground-mounted radials.

The field-strength measurements don't bare out the claims of NEC modeling 
for elevated radials.

Bottom Line: if you can only afford 4 radials -- you should elevate them. 
If you can put down 30 or more -- you should put them on the ground. 
(Unless, of course, you can elevate radials 1/4 wavelength or more above 
ground, in which case the 4 elevated radials win)
