Who is the cable company?
If it's Cox or Comcast they use quad-shield cable, usually Commscope F6SSVV. I have seen TFC (Times Fiber Coax) cable used also, but not within the last several years.
If it's Adelphia, they were using double-shield cable because they were too poor to pay for quad-shield
I have no idea what they're using now that Comcast owns them. Probably quad-shield.
