I am helping a friend re do an old instillation. The installer used perfect vision rg6 cable 2 conductor with a ground. He came out of the house and buried it about 4" underground to run to the pole mounted dish. We are moving the dish due to obstructions and I am going to run a new wire. Question I have is is this cable ok to use for direct burial? Or does it have to be a direct burial cable? It is going to buried underground about 100ft from the house to the dish. I looked a the cable and it does not say burial on it anywhere. It is the standard rg6 all the installers in cincinnati use.
