I just joined up, retired from Data Telecommunications.. Telephone and Data Network. Did Central Office, Special Apps, Sales, Installation/Service, Network engineering, CAMA ID, VOIP, MUX... Now trying to set up my Dish service.. ha.. House was hit by lightning about a day after I finished building it, almost have it rebuilt now.. It took out ALL electronics in the house and outside.. burned up the TV, Computer, Telephones, Security system, everything attached to all low voltage wiring, which included my outsid DISH.. so, now I have a Dish 500 + dish and a Dish 1000 Network dish.. the 1000 has what looks to be a 3LNB on it.. wondering the difference in the two, what is required to use the better of the two, and which is the better? Thanks.. looking forward to a great forum.. Wayne
