All of the unshielded CATx cables have very good immunity to external RF 
and noise if each signaling circuit is carried by one of the twisted 
pairs. The CATx cable carries RS232, which requires two pairs. The two 
remaining pairs connect the key line and logic circuit (ACC2).

In general, a high quality twisted pair is far more important than a 
cable shield ff the CATx cable is properly wired (that is, one pair for 
each signalling circuit). The primary advantage of is higher CAT spec is 
reduced crosstalk between pairs, which is a big deal for Ethernet, but 
much less so for applications like this.
