Grounding a satellite dish

Page 2 of 2  


ALL GROUNDS MUST BE UNIFIED THAT IS CONNECTED TOGETHER FOR SAFETY. As long as they are unified, no ground loops can occur ------------------------------------------------------------------------------------ However, as far as electronics are concerned ground loops can form wherever grounds are connected in two or more locations instead of a tree or starburst arrangements. They can even form on a circuit board if a ground plane is interconnected. If the sheath of the cable is grounded and the electronic equipment is also grounded a loop can form and introduce audio or video noise. In this case a cable isolation device must be used to eliminate such loops.
