There is a question or two on the Extra Class Exam
that makes the same point. You add ground radials to
to a quarter wave vertical antenna to increase low radiation
angle. Gordon West says so on his audio discs.... ;-)

Hi Rick,
I'll have to review this, maybe I am suffering from a false memory, or
an accurate memory of false information. I thought that a poor
counterpoise under a vertical reduced the overall efficiency AND had a
negative effect on the pattern diminishing the low angle radiation more
than the higher angle radiation. N6LF's studies may help clear it up.
The number of radials won't really affect the angle of radiation.
With a poor ground, you will still have a low take-off angle; you'll just
had a heck of a lot of ground losses.
