I Live In Minnesota (chatfield). I Live In An Apartment. I Have Had A Dish 500 Here For 5 Years. I Want To Upgrade To Hd Programing. My Dish Is Not Grounded. If I Try To Upgrade Will I Loose My Dish Because It Is Not Grounded?? There Is A Extra 500 Right Next To Mine. Is It A Good Idea To Try And Get The Tech To Use It For My Hd Programing?? Hope I Am In The Right Spot To Ask This. Excuse The Caps
