I just had Dish installed yesterday. They left me a Extra Dish (DISH 500),Tripod and cable wire to hook up to my camper. I have the dish hooked up to the Tripod and the cable comming straight from the dish to my box inside the camper. They told me I can take my 722 Duo Box and use it with my 500 Dish I just wont pick up HD. I only need standard when I cam anyway. I have the Box Plugged in the wall and the coax wire comming straight from the dish plugged in DISH 1. I have the tripod level and pointed to where the POINT DISH Menu shows. It keeps comming up Total Loss Signal. Is there a special way I have to hook it up in my camper????????? How do I hook it up to make it work. is there a setting or something I have todo???? I called dish put they could help me too much.......
