Product Description
Professional Long-Distance 6G HD-SDI Performance
The AV-Cables Belden 1694A RG6 6G HD-SDI BNC cable is built for professional broadcast, video production and commercial AV applications requiring dependable signal integrity over longer cable runs.
Constructed using genuine Belden 1694A low-loss RG6 precision video coax and professional true 75-ohm BNC connectors, this assembly supports SD-SDI, HD-SDI, 3G-SDI and 6G-SDI video systems.
The full-size RG6 construction provides lower attenuation than Mini RG59 and standard RG59 cables, making 1694A an excellent choice for production facilities, stadiums, mobile trucks, engineering racks and permanent professional installations.
Why Choose Belden 1694A RG6?
Belden 1694A combines a larger 18 AWG solid copper conductor with professional foil-and-braid shielding and full-size RG6 construction. This reduces signal loss compared with smaller coaxial cables and makes 1694A the preferred 6G-SDI option for longer professional video runs.

Long-Distance SDI Signal Performance
Belden 1694A is designed to carry professional SDI signals over greater distances than smaller Mini RG59 and RG59 cable constructions.
| SDI Format | Performance | Common Application |
|---|---|---|
| 6G-SDI | Long-distance 6G performance | High-bandwidth professional video systems |
| 3G-SDI | Extended-distance operation | 1080p professional video |
| HD-SDI | Longer broadcast runs | 720p and 1080i HD video |
| SD-SDI | Maximum-distance operation | Standard-definition serial digital video |
Maximum transmission distance depends on the signal format, source and receiving equipment, connectors, patch panels, bulkheads and installation conditions.
