im in an apartment complex. 3 rooms upstairs, and my place in the back lower level. the 2 boxes are upstairs in the 2 of 3 rooms. My remote has to be moved all around to get a signal, and i looked on the back of the dvr box. It looks like a standard cable hookup, could i connect my 25 foot cable and extend the antenna? I'm the one paying for the dish bill, so i want the best service possible. thanks!
