I live in pittsburgh, pa. i bought a vip 612 receiver to use with dish network. can i set up a dish 1000.2 triple lnb and run 1 coax to my receiver with a dish seperator to get all of my programming? i am just using this 1 receiver. I only have about a 50' cable run so can i get away without running a power inserter? just want to make sure i will be able to get all of my hd channels with this setup.
