Went out Easter weekend for the first time in a year. Had a few glitches but the worst was no sat. tv. I have used in the past a portable sat. dish on a tri-pod with the receiver from one of the spare bedrooms. Well earlier this year we had a up grade on our receivers with hi def in the living room and standard receiver in the bedrooms. When I went to hook up the dish at the campground I could not feceive or find a sat. signal. The sat. finder I was using would not pick up a signal or the signal strentgh through the receiver would work. A camper nex to me was also using Sat. TV and also Direct TV. He helped me with the correct asmut and elevation but still got no signal. When I got home and set it up to the exact settings it still would not work. My question is Would the receiver and dish not be working together, this is the only thing I can think of. HELP
