I am going to be putting a wall socket in for my sky and tv ariel. I would like to know what good quality cables there are to go from the wall socket to the sky box, the only F Type connector cable i can find is the cheap bog standard ones(think argos sells them) and one by QED called Qunex STV which is about £35. How good is the QED one and how much does it improve the picture?? what other ones are there that i can check out ? looking to get one that gives high quality picture, i dont really want to use one of those bog standard ones.
