I'm building a new house and have run RG6 from a central structured wiring panel to all TV locations as well as two runs into the attic to the area where the dish will be mounted. Right now those two cables are just hanging on a truss in the attic, and I'm wondering if there's anything else I should do with those two cables while everything is still open to make it easier on the dish installer so he doesn't have to crawl back into the furthest recesses of my attic to do something I could have done beforehand. Where do installers usually make the penetration from the attic to run the coax outside? Do they typically go directly through the roof? Or do they go through the fascia on the edge of the roof? Or should I just leave it alone at this point and trust that the installer will take it from there when we move in?
