Cable Type

Hi All,

I currently have the floor up in my lounge and thought that this may be a
good time to put in some cabling ready for surround sound speakers (I'm
intending to buy a system soon).

The previous occupants of the house left behind a large amount of the coax
used to run to the Sky dish. My question is, would this cable be suitable to
use or am I best to go and buy something suitable?

Cheers,
Chris
