Did they only give you one satellite box? Typically, a satellite system needs a single box per TV, hence only the one connection in the front. You could pull another line and move the box back and forth...buy another satellite tuner box and add it to the setup and of course call the satellite provider and let them know so they can add it to your bill, or go with a slingbox/slingcatcher setup. The last probably being the most expensive.
