I had difficulty my first time as well with the same setup. On the outside you should have two inputs TV and Satellite. Use the satellite connection and connect from the dish. Then on the inside there are two connections, TV and antenna. The antenna is for use specifically with the antenna. Connect the TV connection to the input of your satellite In on the receiver. Then you will need the RGB cables from the reciever to the television. Hopefully that should work. Then download a satellite finder app to your phone. There are some pretty good ones out there for free. Find the satellite, adjust your dish. Usually a two person job. One moves the dish the other tells you the signal strength. If you are dealing with trees, that makes it tough. Good luck.
