I live in central Arkansas and we like going camping on the river about 30 min south from home. First off after reading lots on here I know that I don't know much about all this so please bear with me. I have a Dish 722 receiver at home for 2 TV's that is eastern ark using the 61.5 and 72 sat. I just picked up a 211 k box and was given a dish by a friend to use. where we normally set the camper up has a good opening to the south, south east so I would like to try to use these same satellites. how can I tell if the dish I have will work with this? thanks for the help.
