They are the same in they both receiver the 110, 119, & 129 locations.
They are different in size as the 1000.2 is larger. Also the 1000.2 uses a DPP LNB that will run 3 receivers so up to 6 tuners with seperators. The 1000 was set up to use seperate LNB's for the sat locations either 3 seperate LNB's, a twin and a dual + a switch, or a DPP Twin and a DP Dual.
