A loop can be very efficient to null out one source of QRM/QRN, due to the very sharp minimum. Further is is rather insensitive to local electric field QRN, provided the shielding is good. But the maximum of a loop is very broad so I'm afraid it won't give any improvement in regard with atmospheric QRN. Maybe a phased array improve SNR due to directivity, at least for those who have the space and a several 100m of coax. 73, Rik ON7YD
