The correct place for the ground wire is on the outside of the house. Lightning follows gradual bends of the ground wire better then sharp bends of the ground wire. Installing the ground wire can be the last to do , get the system up and running first. At my house I have a coax ground block installed on the ground wire that is connected to the mount of the antenna and then coax enters the attic through a roof vent. Most houses are wired with coax that all of the separate coax wires go to location where the house electric service is because thats where the ground rod is at. Cable Tv and Satellite Tv also ground at that location. Some buildings are coax wired so the separate coaxes go to a location some where in the building and then separate coax/s will go to the outside of the building where electric service and ground is at. When building a house it is always a good idea to have a extra coax pulled to each location , comes in real handy later on.
