Having a Faraday screen (yes, a real Faraday one) on a receiving loop can be an advantage, if the area around it is full of e-field interference.

This can be done by having the loop made as a ring of coax. THe ends of the inner used as the loop and going to the preamp, while the braid is cut short a little at both ends and the loop of braid is NOT completed, but gets a single point connection to a local earth.
