Superbat SDI BNC Cable 12G/3G 4K 8K RG6

Superbat SDI BNC cable (Belden 1694A) is a professional 75Ω coaxial video cable with gold‑plated BNC plugs designed to carry SD, HD, 3G, 6G and 12G/4K–8K signals reliably over distances from 1 to 300 feet.

This precision coax is built on the Belden 1694A platform to deliver low attenuation and a wide 4.5 GHz bandwidth in an RG‑6 form factor. Its combination of a solid 18 AWG copper conductor, gas‑injected FHDPE dielectric and dual shielding (tinned copper braid plus foil) gives stable impedance and excellent rejection of interference. Gold‑plated BNC connectors ensure secure, low‑loss connections with professional cameras, switchers and recorders from trusted broadcast brands.

How does this cable maintain signal quality for 3G/6G/12G video?

The cable's materials and construction are chosen to minimize signal loss and preserve timing integrity for serial digital video standards. A solid .040" copper conductor and FHDPE dielectric reduce attenuation while the combined braid and foil shielding keeps electromagnetic interference out.

• Belden 1694A RG‑6 design with 18 AWG solid conductor for low loss
• 95% tinned copper braid plus 100% foil Duofoil for superior shielding
• 4.5 GHz effective bandwidth supports up to 12G/11.88 Gbps signals
• Gold‑plated BNC male connectors for consistent contact and low resistance

Which devices and video standards is this cable compatible with?

This cable is engineered for professional SDI workflows and consumer/prosumer HDTV environments. It supports SD‑SDI, HD‑SDI, 3G‑SDI, 6G‑SDI and 12G‑SDI standards as well as related signals such as component, composite, word clock and MADI where SDI coax is used.

• Compatible with Blackmagic, AJA, Grass Valley, Evertz, Marshall and similar gear
• Works with cameras, monitors, switchers, converters and recording devices
• Suitable for broadcast, live events, studio installs and post production
• Supports both point‑to‑point and rack‑based cabling runs up to specified lengths

What lengths, connectors and physical specs are available?

Superbat offers this cable in a wide range of lengths so you can pick the right run for a studio or venue. The product features BNC male plugs on both ends, 75 ohm impedance, and RG‑6/U style construction using Belden 1694A specifications.

• Lengths: single‑piece options ranging from 1 foot up to 300 feet (select at purchase)
