    You're right. There was an article in QST about that last year some time; the authors erected a quarter-wave vertical and played with various numbers and positions of radials. 32 flat on the ground was indeed the sweet spot but they found that 16 was probably adequate in most cases. Interestingly, they found that if you elevate the radials to about five feet (1.5m) off the ground, you could get by with a lot fewer of them. I can't remember the exact numbers but it was a significant difference.

    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.
