      Well - there are a few applications which use the 8 cores separately rather than as 4 balanced pairs. STP might come in useful there.
     
      Also, it's useful in factory / industrial environments. If you want cable to go anywhere near a blast-furnace, say.

      I've never seen an application that called for it in a domestic / office environment.

            Mark,
           
            If CAT5 is designed for balanced signals, which are (relatively) immune to interference, what then is the point of screened CAT5?
            It's a question I've been meaning to ask for a while (following a previous discussion about ethernet being balanced) and you've just reminded me of it.
           
            Any ideas?
           
            Tony

                  You CAN, if you really feel like it, wrap the CAT5 cable in kitchen foil, and ground one end, which will help a bit...
                 
                  ... But it's fundamentally a crap way to do it. If you're going to carry signals over CAT5, then they need to be balanced. The whole point of balancing is in the rejection of interference (such as shortwave radio.)
                 
                  Doesn't matter whether you're talking 10baseT ethernet, 100baseT ethernet, or KAT5 audio... balancing is the only way to go.

                        I lay as a temporary solution a cat5 cable and i run audio down
                        it to the a set of mulitmedia pc speakers in the bedroom.
                        and for some reason it picks up radio. I can hear
                        a radio program in the audio.
                       
                        any ideas ?
