HD-SDI & 4K UHD Coax

HD-SDI & 4K UHD Coax

Belden SDI-HD and UHD coax cables and connectors are designed for high-performance signal transmission in professional broadcast and AV applications. Engineered to support HD, 3G, 6G, and 12G-SDI signals, these cables ensure superior signal integrity, low attenuation, and robust shielding to minimize interference. The UHD coax series is optimized for ultra-high-definition video, enabling seamless 4K and 8K signal delivery over longer distances. Paired with precision-matched Belden BNC connectors, these cables provide reliable, high-bandwidth connectivity for demanding environments such as studios, live productions, and OB vans.

Features & Benefits

  • 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 skin/foam insulation process provides the right amount of conductor adhesion for easier stripping and improved connector reliability.

  • Compared to SMPTE’s return loss limit, Belden’s Precision Video Coax provides significant RL headroom to account for potential losses elsewhere in the transmission line.
