I should think a combination of both.. The counterpoise serves as the 
"other plate" of a capacitor formed between it and the topload.  From an 
E-field standpoint, you want to have something that extends far enough out 
to cover most of the flux.  From a losses standpoint you want to have low 
impedance within the plate, so high "solidity" is important, although I 
suspect that chicken wire (aviary netting) is more than solid enough.
