I have 2 bedrooms back to back with cable termination in just one of the rooms. Can I split the cable (using a standard coax splitter from Radio Shack) and have uverse in each room (provided I have 2 of their boxes of course)? If that won't work can I split the cable and have uverse in one room or the other by moving the existing box between the rooms? If a splitter will work what type do I need? I bought one that supports up to 2350 hz - the standard ones are up to 900 hz (at least that is what I've found).
