Either (the wing dish with a DP Dual and a DPPlus Twin on the main dish, or a 1000.2) will work to get 129, but you might actually need to get 61.5 instead, if your locals or your local RSN is on 61.5 and not 129. The national HD channels are mirrored on both. If you need 61.5, a wing dish is the way to go.
