[Antennas] Diminishing Returns

[Chris Boone]

Elevated radials, you get beyond 4 radials at 90deg to each other and you
don't see much improvement for the extra work...buried radials are another
issue. Check out W4RNL(SK)'s posting now at DXEngineering....its free..you
only have to register....www.cebik.com is the link to his former site...and
TONS of great antenna data...and he answers your question better than I
could :) IF YOU CAN, elevate the radials 8ft above ground...even if the
vertical is ground mounted (there are AM Broadcast stations done that way
and they get OUT like crazy!)

I realize you can't have too many radials for a vertical antenna, but 
where do you reach the point of diminishing returns.  Out of necessity 
my Butternut HF6V vertical is set on a narrow strip of land and I can't 
fan the radials out in a 360 degree pattern.  I can get about two sets 
of radials for each band fanned out at about 180 degrees, but beyond 
that the spacing between more radials will become rather close.  Would 
more radials placed close together be beneficial or do I have about the 
best I can expect?

I have no previous experience with verticals.
