By installing the Intermatic 1-Line Coax Cable Protector where your coaxial line enters your home, you'll be protecting your cable or satellite line from the surges that can destroy its connected components. The Intermatic 1-Line Coax Cable Protector even carries a 5-year warranty with a $10,000 connected-equipment warranty.

  • More Info

    The surface-mounted 1-Line Coax Cable Protector features two F-thread connectors for IN and OUT connections in addition to a bonded ground lead. Made of epoxy-enameled steel, the 1-Line Coax Cable Protector has been designed to provide protection with a very minimum amount of impedance or signal attenuation. The protection element is completely shielded to eliminate noise intrusion and signal loss. Protection for a second coax line is optional.
