I had my sky installed last week. House south facing at the back so dish had to go there. Cable guy put it as neat as possible just below guttering on back of house, over the roof in a neat line, tacked down along the guttering between my house and next door and drilled a small hole through the brickwork and into the cable box.
I told them I was not getting a telephone so I have no unsightly wires everywhere inside the house.
Was happy enough with the installation, it looks neat and the wires even outside are hardly visible. The dish is put in a place that it is not obvious either.
Some of the other cable jobs on the adjoining houses are absolutely awful, white wires dragged horizontally across the front of the roof, wires going in through the front door, etc.
Have to say, the guy knew what he was about and very professional with his work. Was very happy with the installation and I am a fusspot.
