I pre-wire new homes for telephone and coax. I work with the local Dishnet guy on all of the new homes I do. I also install computer networks in new homes. Sometimes I just run all the cat5 and punch them down in a patch panel and sometimes I set up the whole thing. It all depends on what the customer wants. I don't run cat3 for anything anymore. All cat5. Blue for the computer and yellow for phones. My current custom home wants RG6 ran for the Dish and another RG6 for CATV. They'll use CATV for cable modem and Dish for TV. Every phone/computer/RG6 location gets a steel box with conduit to the crawl or attic so there will alwas be access for future upgrade/reconfiguration.
