You may need a "power pass splitter". It will allow an injected current to go down your coax cable to your dish in the case of automatic dish antennas. Regular splitters will not allow this and generally have no place to inject power. Not sure if this is the OP's problem. It was mine and a power pass splitter fixed it. I use the King Quest Sat Dish with Direct TV.
I use the King Quest Automatic Dish and receiver at my TT, home, cabin and boat. As long as they are both together, it works great and I get local channels.
Only three connections, power, HDMI and coax cable. Otherwise, you would have to pay $7 a month for each receiver. I'm too cheap for that.
