Just left directv for dish network hd gold package with locals. I have a 622 hd dvr downstairs and a 625 dvr upstairs. Both are dual tuner mode for single tvs. Installer put up a dish 1000 and after a while of tinkering got the 129 signals to come in just over 60. Works for clear weather, but I'm worried about rain fade and would like to go ahead and bump up the signal as much as possible with a second dish (say dish 500). My question is how do I do this? What additional equipment/switches do I need? How should the cables be run and connected? My current install has 2 coax cables running from the dish 1000... one going to each receiver. At each receiver the single coax run from the dish is split into 2 coax cables for sat 1 and sat 2 input on the receivers. Feel free to offer any other recommendations or suggestions. Thanks for the help!
