75 Ohm SDI Coax, RG-6, 18 AWG Solid Silvered Copper Conductor, PE Insulation, Foil + 95% Tinned Copper Braid Shield, PVC Jacket, CMR. Belden's skin/foam insulation process provides the right amount of conductor adhesion for easier stripping and improved connector reliability. Specially formulated gas injected high density foam polyethylene is more crush-resistant than standard polyethylene. Even with rough handling during installation, it resists deformation and maintains impedance and return loss characteristics. Belden's Precision Video Coax provides significant RL headroom to account for potential losses elsewhere in the transmission line.
