How to Choose the Right SDI Cable
For Racks and Short Connections
Choose Mini RG59 when space, flexibility and cable weight matter. Belden 1855A is designed for up to 6G-SDI applications, while Belden 4855R supports professional 12G-SDI and 4K UHD workflows.
View Mini RG59 options →For General Studio and Production
Standard RG59 offers a practical balance of flexibility, durability and signal performance. Choose 1505A for 6G applications or 4505R for 12G applications.
Browse professional SDI cables →For Longer Cable Runs
RG6 provides lower signal loss and is typically preferred for longer distances. Choose 1694A for HD, 3G and 6G systems or 4694R for professional 12G-SDI and 4K UHD systems.

Frequently Asked Questions About Buying SDI Cables
Where can I buy professional SDI cables?
AV-Cables sells professional 3G, 6G and 12G SDI cable assemblies directly online at AV-Cables.net. Available options include BNC, HD-BNC, DIN 1.0/2.3, Mini RG59, RG59, RG6, plenum, extension and multi-channel snake cables.
What type of cable should I use for 12G-SDI?
Use a cable designed and rated for 12G-SDI. Belden 4855R Mini RG59 is a compact choice for shorter and medium-length connections, 4505R RG59 provides additional distance capability, and 4694R RG6 is generally preferred for longer 12G-SDI runs.
Can a 12G-SDI cable also carry 3G or 6G video?
Yes. A properly built 12G-SDI cable is backward compatible with 6G-SDI, 3G-SDI, HD-SDI and SD-SDI signals, provided the connected equipment supports the selected video format.
Are ordinary BNC cables suitable for SDI video?
Not necessarily. Professional SDI systems require true 75-ohm cable and connectors. Generic 50-ohm RF cables or cables not designed for the required SDI data rate can cause signal loss, intermittent video or complete signal failure.
Does cable length affect SDI performance?
Yes. Higher-bandwidth formats such as 12G-SDI generally have shorter maximum transmission distances than HD or 3G-SDI. Cable construction, connector quality, patch points and equipment performance also affect the usable distance.
Does AV-Cables make custom-length SDI cables?
Yes. AV-Cables manufactures standard and custom-length SDI cables, custom connector combinations and multi-channel cable assemblies for broadcast, production, commercial AV, government, integrator and OEM applications.
Are AV-Cables SDI assemblies tested?
Yes. AV-Cables hand assembles its professional cable assemblies in the USA and individually tests completed cables before shipment.
