Just moved into a new house, and the laundry room door is about 4 feet away from the utility pole that provides the coax cable for internet service. So, I can literally plug my modem directly into the splitter at the top of the pole. However, I need to route this cable to a more practical location within the house, which means putting on a splitter and running the cable in the attic. Should this cable be grounded to something, like a piece of conduit or a water pipe? Or is that not necessary? I assume it's grounded at the pole, but should I ground it to something in the house just in case?
