I am almost done with my installation of my 8 foot C-Band system. I have one last question. The back of my 4DTV 922 receiver has an LNB input for both C-band and KU-Band. But, my LNB seems to have the C-Band and KU-Band merged into one with a cable cord hook up and 1 output to go to my TV. Will this single cord bring both C-Band and KU-Band into my house and if so, do I hook it up to the C-Band or KU-Band connection in the back of my receiver? My installer wants to know if he needs to string a second line into my house.
