well the reason y i asked this is because i recently got a dish 500 from dish network and i cant seem to find a signal. i noticed that in the system info section there was a internet address. which leaves me to believe that it the reciever has to connect to the internet in order to recieve dish channels. i could be wrong. my parents called cs and they said that a phone line was not required. i did some internet research and found out that if u paid a 5 dollar phoneline fee then it isnt required. but i also read that this type of dish required a phoneline. i think that this one is a dual because there are to slots but one is for 119 and the other is for 110. i guess that u could have one reciever set to 110 and the other to 119. either way i still cant find a signal. it seems that everything is connected correctly. there are trees but only in the back yard. theres like one in the front. we cant put it on the house. so i was goin to nail it to the only tree in the front yard and go from there. i spent all day yesterday moving around with the satellite trying to get a signal but i cant seem to find one. if there are any satellite peeps out there i could really used the help. thanks for the help
