AND -- a critical part of the design of these structured cables (CAt5, 
5e, 6, etc.) is that they each have a different "lay" (the technical 
turn for number of turns per inch) to minimize crosstalk, so a single 
CAT6 could conceivably carry signals from for antennas. And, because 
they are carrying data, they also have fairly good bandwidth.

Several years ago, I published an applications note on the design of 
common mode chokes for receiving antennas using a single CAT5 pair on 
small ferrite cores, and for isolation transformers for RX antenna. It's 
son my website, k9yc.com/publish.htm
