How many RG6 cables do I need to run from the approximate location of my HDTV dish to the structured wiring panel of my house prior to drywalling to assure I have enough? The dish will have 2 dual LNBs and the third LNB for the local stations in Greenville SC(110 degrees). Does that mean 5?? Do the new dishes come with a 4 output switcher to allow up to 4 recievers?? Thanks for the help. We are drywalling this week.
