The Monster Power Home Theatre POWERBAR™ 1100 is equipped with fast-acting, high capacity Multiple SurgeGuard™ Circuitry which instantly detects any voltage surge or spike and immediately suppresses it BEFORE it can even reach your components. Plus, we've designed the POWERBAR 1100 with 3 sets of coaxial connections and 1 pair of phone jacks, so you can hook up your satellite receiver, cable box or HDTV antenna for total home theater system protection. BEST of all, unlike other surge protectors, Monster's ultra low loss RF circuitry provides maximum protection with virtually NO SIGNAL LOSS.
