I purchase this unit about 2 month ago . before I get it , I be use a Radio Shack brand amp . I get that amp originally because of the distortion , and freezing up of the picture , many time a day . it help a little bit , but not half of what it should have do . now I do some research and find this Motorola unit . so far , it have work fairly well . I hook it up outside my home where the cable come to my home . it be inside the plastic housing where the one cable be split into 6 to feed 6 different outlet . I have 5 tv 's and the other be split between my cable modem and another tv set . the internet connection be amplify , but so far have not affect it be function . we be get a great reception on all we set also . that be most of the time . I say this because the digital picture , although very clear and crisp , it do have a hiccup-where the picture will freeze for maybe a second . that do not happen very often . this amp be extremely easy to use , and I would recommend this product .
