Your Sunrise has a coax cable in the basement electrical compartment that is intended for cable TV hookups. You can do one of two things. You can either use this cable for satellite TV or you can string a new one for SATV.
If you use the one that's there you'll have to do some switching on the other end. As it is, it goes to the cable TV input on the video input selector switch by your VCR. This takes standard RF signals and routes them to your TVs and the VCR. You would have to disconnect it and reconnect it to your SATV receiver or else you could hook up an A/B switch to send it to the SATV reciever or the CATV input on the video selector. Then you just flip the switch, depending upon what kind of signal you have hooked up to the other end of the line.
If you don't want to do this, you can just string a second coax cable from the basement up to the satellite receiver. That's what I did on my 2003 Suncruiser. Then you don't have to worry about flipping switches or goofing anything up.
