We can find all sorts of articles based on models.

The only A-B comparisons I'm aware of where only radials 
were changed are mine and N7CL's.

There are some FS measurements at WVNJ, but since that is a 
directional array they might be the subject of some 
scrutiny.

After two tests on 80 at two locations and a test here on 40 
meters, the claim four elevated radials can only be equaled 
by 60-120 buried radials is wrong.

Also Hams tend to think in terms of too many radials. Things 
get really flat after 50 radials.

The most surprising thing I learned is how little base 
impedance actually means when guessing efficiency.
