Alas, if only this was true.
Google "radial system design and efficiency in hf verticals" and you should get
a cached version of Rudy Severns' paper of the same name. In it he states:
"Alternately we can graph efficiency in terms of Ga as shown in figures 3 and 4.
Unfortunately this also shows how inefficient verticals are even over very good
ground. Very depressing! For example, with very good soil (0.02/30) and 128
1/2-wave radials, the efficiency of a 1/4-wave vertical is still only -2.76 dB
(53%)!"

It doesn’t take much effort to get to 50% efficient with a quarter wave or
longer wire, and a few short radials.
