Dish Network uses two arrangements, Eastern Arc and Western Arc.
Western Arc is 110,119,129. Eastern Arc is 61.5 and 72 (77 has been taken out of service in most if not all of the US).
A Wally will receive either. If you have conventional tripod mounted dish you will need either 2 dishes, one for EA and one for WA so you can choose, or if you can find a 1000.4 Eastern Arc dish it can be used with a western arc LNB with a small mod to the LNB.
The further east you are western arc becomes more amd more problematic because 29 is low in the sky, if you have tall trees in the line of sight you're done. The eastern arc sats are much higher above the horizon.
At home I hit the western arc sats, at the campground I use the same Wally on Eastern arc 99% of the time.
