Category 7 cable has each cable pair shielded, along with an overall shield. If your network is not Cat7 then the screens are floating, and, as one end is connected to the Touch, which *does* have a connection to the screen contact you will get an effective radio aerial. If the screens in a Cat7 installation are properly grounded to a common point, then you have the opposite occurring - you have a very effective Faraday shield, and the screens do not act as an aerial. There's nothing wrong with using Cat7 cable, but, as you have found, a single piece inappropriately used can be pretty disastrous.
