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.

To answer your question Larry, I don't see any reason why a folded dipole would receive any less noise (local or otherwise) than a single wire dipole.

 If the folded dipole fits in the backyard and the classic dipole needs to be strung over a house, the folded dipole probably will be quieter. Experimentation is key.
