I had a direct tv tech out to my house yesterday to install the dish and it has to be on a pole because im renting the place, he placed the pole on the corner of my house and my neighbor has direct tv and our houses are only like 8 ft apart and their dish was on the side of their house maybe only 3 ft higher then my dish which was installed on a pole well anyways he says he can not find a signal and it cant be installed. Can he check the signal from outside i thought he had to check on the tv? The guy had beer on his breath so i dont know if that had anything to do with it but my question is if direct tv could not find a signal would i be able to use dish network? and he just connected it through my cable lines that are already have and the previous owner has not had the cable turned off yet i dont know if that would make a difference or not. thanks for the help
