I'm wanting to add Indy HD locals to my Absolute package. Currently have Two dish 500's,one with the single adapter pointed at 61.5. My question is, would my signal strenghs be higher with present set repointed at 129 or using a used Dish 1000.2 I can purchace off of Craigs list at a good price. I only run a VIP622 and have two lines run to the tuners. Any advice?? Thanks
