I am kind of new to this unit, but have aimed dishes. The unit is fixed for 101 satellite is this the main Directv sat? Does the unit still work as it is?, or will I need to use a different receiver?

Does anyone know where I can find a replacement battery for my SatGo unit? Internet searches have been fruitless. I stumped the guys at BatteriesPlus. I thought about disassembling the pack and seeing if I could replace the cells. But that is a last resort. Thanks. Sean
