[Exede] grounding question

Hi Everyone, Newbie with a question. I had Excede installed on the roof of my home and the installer drove a 8 ft grounding rod to ground the system. It is on the other side of my home from the Homes Electrical grounding rod. The cable comes from the dish into a ground block and then a ground wire goes to the rod in the ground. Does this grounding rod need to be connected to my Homes Main grounding rod? If so, how should I do this or should I call Excede and have them come out to do this? Thanks in advance for any help.
