I recently purchased a satellite dish, it is a DISH 500, 50' of coax cable and a tripod to use when we are at the race track. My receiver is a model D07/D08. I cannot get a signal, regardless of where I sit it or how I angle it. I have one RG coax cable connected to the 119 side on the dish. My receiver has splitter going to TV1 and TV2 where it says dp+. That splitter and another cable that is connected to an input that says channel 21 -69 out go into a splitter that has the one coax cable from the satellite. No amount of adjusting gets me a signal strength. I don't know what else to do. Any help is GREATLY appreciated.
