A little background first, we have DirecTV installed and it runs from the dish to the cable cabinet in the master closet where the swm module is installed with a splitter. From that splitter there is coax to the master bedroom where there is another splitter with one connection to the box there and the other connection goes outside and then downstairs to the main box. The problem is the cable that is outside has been chewed off by our dog. I looked into it and there is a pre run cable in the wall from the cable cabinet to the main box. I checked continuity and there is a solid connection but when I connect ot to the splitter the box will cannot connect to the dish. It's hard to believe that the pre run cable would not support the directv signal because from the dish to the cable cabinet it is using the pre run cable. Has anyone seen this before? Should I just replace the cable outside?
