Topband: Question about on ground radials field.

[Artek Manuals]

Not a simple , on size fits all answer

What happens depends on the frequency  you are talking about     ( I 
assume 1.825 but if it is a multi band vertical ..then???) and how much 
above the ground plane you are talking about

And the approximate foot print of your radial systems ( square lot 
filled in with radials ?)

on 160M the raising of a few feet will likely have little affect if any 
on the overall efficiency of the antenna if that was what you were hoping?
