PRODUCTS / SPECIALTY CABLE / HYDROBLOC™ WATER-RESISTANT CABLE / Coaxial
 
     
  HydroBloc™ Coaxial  
         
   
  The Gepco® Brand HydroBloc™ high-definition & CATV video coax series for wet locations features a precision center conductor, TactiCel™ gas-injected foam dielectric, excellent crush resistance, and broadband shielding. The gas-injected foam dielectric and precision process control are critical factors in achieving superior electrical performance including faster velocity of propagation, tight impedance tolerance, low attenuation and low structural return loss across the entire 4.5 GHz bandwidth (HD Coax). Conductive elements consist of a precision-drawn solid copper center conductor with 100% foil shield (HD Coax) and 95% braid coverage for complete broadband shielding. The water-blocked construction with a two-ply water-blocking tape prevents transverse and longitudinal water ingress.
