I have this equipment ordered after many other attempts (eg single amplifier etc.) have failed to get an interference-free television picture. On my cable connection running two flat screens, each with digital cable TV. The first connected TV had from the beginning, crystal-clear image. However, the second television had a bad picture (block noise, etc.). After connecting the distribution amplifier both TV had a good picture. The distribution amplifier has definitely paid off and is worth every penny. I would recommend it at any time !!!
