For what it's worth, I wired my whole house with unshielded CAT 6 cable, 
before the shielded stuff and connectors were available. While I do have 
a bunch of ferrite on the cables at the router, etc., I've had no 
incoming RFI problems, even on 160, where I feed 1.5 kW to my shunt fed 
tower about 15 meters from the house. I suspect some of the router 
birdies I hear are coming from my own router, and perhaps shielded 
cables would have reduced them. I'm not sure how much it would really 
help, as all my neighbors have routers, too. In any case, I'm all done 
crawling around in the attic insulation, so those cables aren't going to 
get shielding.
