I buy this 100% John. Ask Paul C about TX loop results when he mounted one 
next to his tower.

The 're-radiation effect' from other conductors is exemplified to a 'T' by 
trying to test a loop close to the house. Not only is the directional 
pattern messed up but the noise is horrendous! And it's usually not the kind 
of noise that is generated IN the house. The network of house wiring 
becomes, as that old TV commercial for plug-in antennas says, "a giant 
receiving antenna"  ......and the loop couples right into it. I still have 
an image in my mind of someone's large LF loop mounted on their back deck. 
This can't be even close to the best location. I always measure a 35ft 
minimum acceptable distance from the house when I walk a loop around the 
property while listening to the portable SVM.

NC was getting just too much recognition :)
