[BC] Ground system

[Tom Spencer]

OK; I can see that, but then - real world experience seems to indicate 
that with buried radials, the improvements drop off after about 90 
radials, and the difference between 120 and 160 is negligible.

And from what I recall reading not too long ago, elevated radials tend 
to maximize efficiency at four.  Adding two more - for a total of six - 
offers little or no improvement in far-field signal strength.

Or did I misread something?

Therefore, the cross section of each spalyed section is more or  less irrelevant.   What is important, is how much of the field is intercepted by  the return conductor, and how much is not.
