Connect High-Density and Standard BNC Equipment
HD-BNC is a compact professional 75-ohm connector used on broadcast equipment that requires more video connections in a limited amount of panel space. Standard BNC remains widely used on cameras, switchers, monitors, converters and other professional video equipment.
This HD-BNC-to-BNC cable connects those different interfaces while maintaining a professional 75-ohm signal path. It is ideal when one device has an HD-BNC port and the other has a traditional BNC port.
Belden 1855A has a nominal outside diameter of approximately 4.04 mm, making it smaller and lighter than full-size RG59 or RG6. Its compact construction helps simplify cable routing through crowded equipment racks, mobile production trucks, fly packs and camera systems.

HD-BNC vs. Standard BNC
HD-BNC and standard BNC can both provide professional 75-ohm SDI performance, but they use different connector sizes and are not directly interchangeable.
| Feature | HD-BNC | Standard BNC |
|---|---|---|
| Nominal impedance | 75 ohms | 75 ohms with professional video connectors |
| Connector size | Compact high-density design | Traditional full-size design |
| Connection style | Bayonet-style locking connection | Bayonet-style locking connection |
| Primary advantage | More connections in limited panel space | Widely used traditional broadcast interface |
| Directly interchangeable? | No—requires a matching HD-BNC port | No—requires a matching standard BNC port |

6G HD-BNC to BNC Cable FAQs
What connectors are installed on this cable?
This cable has one genuine Kings 75-ohm male HD-BNC connector and one genuine Kings 75-ohm male standard BNC connector.
Is HD-BNC the same as standard BNC?
No. HD-BNC is a smaller high-density connector. HD-BNC and standard BNC have different physical sizes and cannot be connected directly to each other.
Does this cable support 6G-SDI and 4K UHD?
Yes. Belden 1855A is a 6 GHz professional video cable designed for compatible 6G-SDI and 4K UHD equipment.
Does this cable support 12G-SDI?
No. This Belden 1855A assembly is intended for SDI formats through 6G-SDI. Select a Belden 4855R HD-BNC cable when single-link 12G-SDI support is required.
Can this cable carry 3G-SDI, HD-SDI or SD-SDI?
Yes. It is backward compatible with compatible 3G-SDI, HD-SDI and SD-SDI equipment.
Why should I choose Mini RG59?
Mini RG59 is an excellent choice when flexibility, reduced cable weight and compact routing are important. Its smaller diameter is particularly useful in high-density racks, routers, patch panels, fly packs and mobile production systems.
What jacket colors are available?
Standard colors include black, blue, red, yellow, green and white. Availability may vary by selected length and current material inventory.
Are custom lengths available?
Yes. AV-Cables can manufacture custom lengths, matching cable sets and production quantities for studios, broadcast facilities, production companies, integrators, government installations and OEM projects.
