Laird Belden 4855R 12G-SDI Cable HD-BNC Male to BNC Female 1 Foot

The Laird Belden 4855R HD-BNC Male to Standard BNC Female 12G-SDI Cable 1 Foot is built for tight broadcast racks, high-density routers, jackfields, and video distribution systems where clean signal performance matters.

This low-profile adapter cable connects an HD-BNC male end to a standard BNC female end, making it useful when working with compact 12G-SDI gear and traditional BNC infrastructure. It is designed to carry high-resolution, uncompressed 12G-SDI and 4K UHD video signals with reliable 75-ohm performance.

Built with Belden 4855R low-loss Mini-RG59 coax, the cable supports 12G-SDI transmission distances up to approximately 149 ft / 45m. The silver-plated copper conductor, gas-injected foam HDPE insulation, bonded Duofoil shield, and tinned copper braid help improve return loss and reduce attenuation compared to many standard coax designs.

The HD-BNC connector uses a familiar bayonet-style lock, similar to a standard BNC, so it feels secure and practical during installation. Fully compatible with SMPTE ST 2082-1 and ST 2081-1, this cable is a solid choice for 4K broadcast, post-production, routing, and signal distribution workflows.
