Dwight, here’s one example of a shield twisted pair: Belden 12/2 5000FE:

Twisted pair. Foil shielded. Ground.  I looked at this and found a cheaper, 
non-plenum version from another brand (will get you the exact name in a 
separate post). 
So I’ve replaced all zip cable lines and many of the smaller Elecraft lines 
too. Trashed the noisy Samsung switching PS (14V DC) used for the Elecraft SVGA 
display and made a new shielded cable to the Powererx PS and on and on.
Highly effective method to reduce RFI. Pretty convinced noise is not going to 
enter the system through these shielded cables.
