we house have 3200 + sq. ft. of live space on three level with several cable tv outlet throughout the house . the associate cable run for these outlet be long and thus a lot of signal loss . in fact i do not have enough signal to operate a cable box anywhere except for one location in the house . needless to say the tv reception be marginal at best in most of the house . after install this product I have enough signal strength to put a cable box anywhere in the house . the tv have never have such good picture quality . my internet speed increase substantially . installation be a breeze . I would definitely recommend this product for those experience problem such as mine .
