I have an elliptical dish for my direct tv receivers. I have two LNB's at 119 and 101 degrees. I have two cables going to my TIVO in one room and I have two cables going to another room ( I wanted the option one day of adding TIVO to the other room.) I just bought an HDTV Direct TV receiver. I see that TERK has a Upgrade kit for SAT-C for 110 degrees LNB so I can get HDTV signal to my receiver. The question I Have it looks like you combine SAT-B with the SAT-C with a splitter. Will this affect my other BOX without HDTV. and if eventually I Upgrade the other BOx do I have to I get Sat-C to my other room.( Another splitter?) please help
