after go through 2-3 different signal booster -lrb- both active and passive powered\/non-powered -rrb- I end up with this . why ? simply because it do what be advertise and continue to do so . Cable TV\/Cable Modem signal booster . I have try several other brand and they work fine for period range from 3 month to just over 1 year , and then there be signal loss through certain bandwidth or the entire unit fail . enter this unit , which I buy through a recommendation by a friend who I have see use it for over 3 year . simply plug and play , and it work . do not get any easier . Cable modem for datum , and tv all work wonderfully and have not fail . so far it have and continue to be the longest lasting signal booster I have use .
