Hi, this is Mike with DISH Network. As everybody has mentioned up to this point, you will need a new dish. The designated dish is dependent upon where your HD locals are found (Eastern Arc 1k.4 or Western Arc 1k.2). Most Dish'n It Up's (upgrades by their promotional name) will come with the best box available based on supplies in your particular market area. As of right now, that box is typically a 722/722k. Also, I would like to give props to everyone who posted this information prior to me. It is always nice to hear that your experience with DISH Network was good, as Argji posted. Let us know if you have any further questions as we're here to help!
