Viper Series 12G SDI BNC Cable

The Monoprice Viper Series 141297 is a 100-foot BNC cable built for professional UHD-SDI workflows. It carries 12Gbps bandwidth to handle 4K video at 60Hz across studio, mobile truck or home installations. The RG-12 coaxial design uses a solid 16 AWG annealed copper centre conductor for reliable signal integrity over long runs.

Dual Shielding and 75-Ohm Connectors

Dual copper and aluminium braided shields protect the signal from interference while keeping the cable flexible for routing. True 75-ohm BNC male connectors with gold-plated contacts and nickel bodies maintain impedance match. Highly foamed PE insulation minimises attenuation across the full 30.48-metre length.

Upgrading from 3G or 6G SDI Links

This cable replaces older 3G or 6G SDI runs that cannot sustain 4K 60Hz without compression or signal loss. The jump is worth it when moving to 12G-SDI equipment that demands the full 12Gbps path. It is not suited for applications requiring fibre-optic reach or multi-camera sync over a single strand.

Questions about this item

How do I install the 16 AWG solid copper centre conductor with the 75-ohm BNC connectors, and what step do people get wrong?

Strip the highly foamed PE insulation cleanly to expose the 16 AWG centre conductor, then crimp or solder the gold-plated BNC pin; the common mistake is nicking the conductor or leaving dielectric debris, which raises VSWR on 12G-SDI paths.

What maintenance or replacement will the dual copper-and-aluminium shielding need later?

Inspect the braided shields periodically for oxidation or braid breakdown at flex points; if attenuation rises on 4K@60Hz runs, replace the cable — no user-serviceable parts inside.

What limit appears first during sustained 12 Gbps UHD-SDI transmission over the 100-foot length?

Attenuation of the RG-12 coaxial construction at 6 GHz (12 Gbps) is the first limit; signal loss grows with length and temperature, so verify eye-pattern margin at the far-end 75-ohm load.
