This is just surge protection (supposedly). Also most "grounding" by installers is not NEC-compliant. Note that grounding is designed to protect people - not equipment. So even in the best of circumstances things get fried. Grounding as practiced is designed to draw static from the dish and route induced voltages away from your home. A direct lightning strike is going to melt any ground you have. So do as much as you can afford. If you have an adverse event and nobody is injured - it's a success.charlesm said:The system was grounded by the installer. My question is if you use one of those power strips that have in/out connections for the Satellite cable, should you use them or will this create a ground loop?
