this professional , durable booster work better than expect . I think I would need to call in the cable company to re-wire the whole house , but this thing do the trick . in a 3-floor house where the cable enter at the top floor , I be have difficulty on the first floor receive a signal on my digital cable box . I call the cable company , which the automate announcement say that it be go to send a signal to the box , but that do not work . I call the main number , and they want to send someone out . I have get my signal split so many time , and I do not want to be scrutinize , although it be all legal I learn later . after install this booster inside the house on the top floor where the line be split the first time , the box way down on the first floor show some activity on the display that I do not get originally without the booster . I then call the automated number of the cable company , and it send a signal to my box . it work this time ! and the picture look great with no pixelation ! it be worth a try . very easy to install . durable construction -- not like the cheap one that be on the market year ago before digital .
