I am looking to possibly add a Dish 500+ for my 110 / 118.7 / 119 satellites and leave my Dish 1000 dedicated to the 129 satellite......In searching for the DPP44 I have seen it listed with a power inserter. Some vendors show the DPP44 switch with no mention of a power inserter. My receiver is a VIP622......Is this something that is required for the switch to function properly?? Does it automatically come with the power inserter and its just not listed......Any advice would be greatly appreciated......Thanks
