Topband: Question - optimum number of radials

[Joe Subich, W4TV]

N6LF has done quite a bit of actual testing of various in ground and 
elevated radial systems.  See: http://www.antennasbyn6lf.com/

K3LC has done extensive modeling of both in ground and elevated
radial systems: http://www2.gcc.edu/dept/elee/Faculty/Christman.htm

However, if the majority of your on/in ground radials are only 0.1 wave
you won't need many before the point of diminishing returns.
