I'd guess the sum of all the individual loops, which should be in their average direction, i.e. with the flux coming out of the middles of the remaining quarters not covered with wire.=20 So I'd guess that you'd have the same radiation pattern as a similar coil wound all in one plane. 73, Chris G4OKW
