It's good to learn new things.
There may be a reason why a folded dipole
could receive less noise than a single-wire dipole. It has to do with balance and the ingress of noise (probably mostly local noise) via common-mode on the feedline (in the case of coax feed). I came across the link below, wherein there is some information on the self-balancing nature of folded dipoles. The self-balancing minimizes common-mode feedline radiation, even in the case of imbalance in the feedline/system. Less feedline radiation, and possibly the antenna balance itself, could result in less receive noise, in some cases.
