Thank you for the reply. Now I am even more confused as I have heard it both ways! If I could ground it inside (or find any other way to have the coaxial not run the length of my house) I would gladly pay DTV to come out and rewire it.
Unfortunately they won't touch it. Back in the day we could do what ever we wanted then they slowly started making changes (weekly basis) and now it's become if we can't photograph it on the outside of the home it's a fail. If it's not Directv approved cable (says Directv and is solid copper) it's a fail, if the ground block is mounted to inside a cable box (outside of the home) it's a fail, they've changed so much that it's become almost impossible to pass a QC these days.
