While Belden makes the best Ethernet cable by far, I have not found it to 
make any improvement in RFI. As others have noted, it's all common mode on 
the cables, and BOTH ENDS OF EVERY CABLE IS A NOISE SOURCE! Radiation is 
NOT the result of any defect in the cable, but rather inferior output 
transformers that put common mode onto that cable. 



Quite so and thanks for the help..
The PDF also makes several point 

one about ground loops 

and another point how streaching of the cable affects
the rfi/emi preformance.
