RG59/U 75 Ohm BNC Cables
Professional 75 Ohm RG59 BNC Cable Assemblies
Professional RG59/U BNC-to-BNC coaxial cables for CCTV, video monitoring, studio, commercial AV and other compatible 75-ohm video applications.
Built with 75Ω dual-shield RG59/U coax and professional BNC connectors for reliable video signal connections in fixed and portable systems.
75 Ohm RG59 BNC Cables for Professional Video
RG59/U is a widely used 75-ohm coaxial cable construction for video and other compatible 75Ω signal applications. These assemblies provide a straightforward BNC-to-BNC connection for equipment requiring standard RG59/U coax.
AV-Cables RG59/U assemblies use 75-ohm dual-shield coax with a foil shield and copper braid to provide shielding against interference while maintaining a flexible, practical cable construction.
Common RG59/U BNC Cable Applications
- CCTV and security cameras
- Video monitoring systems
- Studio video equipment
- Commercial AV systems
- Boardroom video systems
- Video distribution equipment
- 75Ω equipment interconnects
- General-purpose video connections
RG59/U Cable Construction

Standard RG59 BNC vs. SDI BNC Cable
Both use 75-ohm BNC connections, but the cable requirements are different depending on the signal and equipment. For professional SDI systems, choose a cable specifically designed and rated for the required SDI format and transmission distance.
| Cable | Impedance | Best Use |
|---|---|---|
| Standard RG59/U BNC | 75Ω | CCTV, monitoring and compatible general-purpose video systems |
| Professional SDI BNC | 75Ω | HD-SDI, 3G-SDI, 6G-SDI and 12G-SDI broadcast video |
75 Ohm vs. 50 Ohm BNC Cable
BNC describes the connector style, not the impedance. These RG59/U assemblies are 75-ohm cables intended for compatible video and 75Ω equipment.
If your equipment requires a 50-ohm connection for RF, wireless, communications or test applications, use a properly matched 50Ω cable such as RG58 or RG223 instead.

RG59 BNC Cable Frequently Asked Questions
Is RG59 a 75-ohm cable?
The RG59/U cable assemblies in this category are built for 75-ohm applications and terminated with BNC connectors.
What is RG59 BNC cable used for?
RG59 BNC cable is commonly used for CCTV, video monitoring, studio equipment and other compatible 75-ohm video connections.
Can I use this RG59 cable for SDI?
For professional SDI video, use a 75-ohm cable specifically rated for the required SDI format and transmission distance. AV-Cables offers dedicated SDI BNC cable families for those applications.
Is 75-ohm BNC the same as 50-ohm BNC?
No. BNC connectors are used with both 50-ohm and 75-ohm systems. Match the impedance of the cable to the requirements of the connected equipment.
