  Direct Burial HDTV Coax  
         
   
  High Definition coax for direct burial applications. The direct burial series features the same precision center conductor, gas-injected dielectric, and broadband shielding as the riser rated versions, but with a polyethylene jacket and water blocking tape. The polyethylene jacket is exceptionally puncture resistant and inert, while the water blocking tape absorbs moisture and prevents migration. As with all Gepco High Definition cables, the direct burial series has a 3GHz bandwidth, low attenuation and return loss, and meets or exceeds SMPTE 292M standards for uncompressed High Definition video interconnects.
