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.

The PDF also makes several point
one about ground loops
and another point how streaching of the cable affects
the rfi/emi preformance.
