Definitely run the cat 5 like Claude suggested, as many set-top boxes now have ethernet and use it for various functionality. Not just Dish, but also DirecTV, Tivo and cable, and even some TV's. In Dish's case, if you have broadband run to one or more of the boxes, you don't need the landline to the boxes. RE: buying v. leasing, many here will say it's generally better to lease now, as you don't save anything on monthly fees any longer - you get charged the same monthly receiver fees whether you own or lease. Dish will probably install for free for what you're needing, since you've already run your own cabling, and they'll bring everything you need - likely a western arc dish and your receivers. They usually want an installer to do the install, and won't let you do your own, in order to assure it's done properly. (I'm assuming you're a new customer for them.) I'll let others here who are installers answer the code questions, but you shouldn't have anything to worry about there if you get a good installer. If you don't like the way he's doing it, don't sign off on it and have Dish send someone else.
