I just recently replaced the cable from my living room to the splitter that feeds the house and it made a HUGE difference. You'd be surprised how much is lost by old crappy cables. I use to have to use two amps, one at the box and one at the splitter under the house, just to get a decent signal to my living room. With the new cable run I don't need any amps at all and I still get 95% or better on all my channels.
