The narrower bandwidth of arrays has to do with geometry (spacing,
azimuth, elevation) and phase relationships between the drive to the
elements. I wouldn't expect fattening the conductors to have MUCH
effect on that. But it would certainly broaden the resonance and
reduce the losses of a single element.
