SKY/satellite cable quality
Discussion
Hello all, first time posting in this section 
The position of my TV means that the cable from the sky dish will have to come down an internal wall (if it enters the house from an external wall it won't be anywhere near the telly).
There is an existing crappy old co-ax cable in an ideal place that I can use to pull through a new length of decent stuff. However, it is extremely close to a ring main for the downstairs sockets.
Is there a decent satellite cable available that is sufficiently shielded so that even if It's run alongside mains cable it won't pick up any interference?
I don't yet have sky installed but I want to run the cable in myself as I'm sure the sky man will want to drill it through an outside wall for convenience and quickness.
If I can run it where the old co-ax is it will save me hacking out the plasterboard, I'm sure that cable runs through another internal walk upstairs and them into the loft (previous house owner must have installed it).
Any help much appreciated.

satellite lnb cable is co-ax.
Yes, but sky uses something with two separate feeds I believe (like a pair of cables joined together)? Is the stuff they use sufficiently shielded against mains interference? If not, what is? Judging by the rest of the previous owners DIY efforts, the existing co-ax will be dog poo quality.

Isn't the two feeds thing just for SKY+ so you can watch one thing while recording another?Judging by the rest of the previous owners DIY efforts, the existing co-ax will be dog poo quality.
Mains interference isn't that big a deal with digital RF, you won't get noise or hum particularly so all you really need is a low loss shielded cable. CT100 would be fine, and it's fairly cheap. It's what we use with radio cameras on live broadcasts, with runs of up to 100 metres without major issue, and we are passing a much higher bitrate down it than you'll be receiving on your SKY dish.
Thanks for all the replies, very helpful
I'll use two lengths of decent cable as recomended, rather than the "single" dual pair type stuff that SKY use.

If you want to read about cable for satellite use and related topics have a mooch around the Satcure site.
That a very informative site, thanks for the link Gassing Station | Home Cinema & Hi-Fi | Top of Page | What's New | My Stuff
