To some degree. If possible, try running the counterpoises out by
zig-zagging them, running them along a fence, or both.

Just womdered if the performance of a counterpoise is compromised if it is
coiled up rather than laid out straight? I have a whole bunch of quarter
wave counterppise wires for my end fed long wire. Am I shortening their
electrical length by coiling them?
