The RF Notch Filer blocks incoming cable TV channels 75-80, allowing the Media Center Modulator or Component Modulator to broadcast an in-house "security" or "entertainment" channel without interference. The Notch Filter simply couples to the coaxial cable TV input on either a splitter or an active video distribution device such as the Leviton 3x8 Enhanced RF Distribution Module. Once installed, it filters out six cable channels to make room for any home security or entertainment video application. It also blocks outgoing signals, such as cameras, from being broadcast outside the home.
