Extending coax cable - ground wire needed?

While I have the walls open for some other work, I'm looking to add another coax jack. I have seen some coax labeled as "with ground wire" and others not marked as such.

I have satellite TV. As far as I can tell, things seem to be properly grounded where the service enters the house. There is a solid copper conductor that runs from the cable box on the side of the house, and into the main panel in the basement. Do I need to use coax in the house which is marked as "with ground wire?"
