I have had problems with Sky installations including second old Sky boxes used just for Freesat reception, or multiple standalone Freesat STBs. One box alone works fine, but a second or further box either does not work properly or the first system develops problems.
Some of the boxes or just some channels on boxes report "No Signal" etc.
This problem can sometimes be sorted by connecting the cable shield to the domestic earth. - a plug just wired to the earth terminal, and connected to the chassis of the STB.
Sky Dish installations are almost never earthed by the installers.
If you want to this properly, and take precautions against lightning strikes on the satellite dish, the cable from the dish should travel down the outside wall to an earthing bar, where the cable sheathing is connected to a good earth point (earth rod or domestic earth bond) before the cable enters the house. The dish itself should also be bonded to the earthing bar.
