I run my cable from the dish LNB direct to the Key tv box screw it to the satellite connect connection from there it goes to the receiver box from box to tv with HDMI cable works perfect. IF something wrong with Key tv box you can remove it and unscrew cable from back off satellite connect and tie your dish LNB cable to cable going to receiver with a barrel connector. If I recall there are four different cables connected to the back of Key tv box all different colors going to different places in the camper. Just check color find it at the tv.
