You gotta either use a permanent dish mounted to ur trailer, or a portable one on a stand outside...my setup goes from the outside dish to the 'switch' which is plugged into the external sat input, then on the inside i have a dual tuner box plugged into the sat output with an hdmi cable to the main tv, then the second tuner output backfed through the trailers cable input. So i can watch one program in the main room and something different in the bed, bunk, and outside. 4 tv's total....but yes....the connections you have are just for connecting dish....you still need the sat and receiver boxes.
