Got an old prime star dish and LNB with the dualoutputs(H and V) I want to get the 121 sat on both my Blackbird and DP501 receivers if posible. Whats my cheapest and easiest way to do this? I have a DP QUAD set-up and some legacy single LNB set-up to work with. I also have a DP34 multi switch in the closetand some old sw21 switches too.
