Product Description
Professional 6G-SDI BNC Male-to-Female Extension Cable
Extend an existing SDI cable without using a separate barrel adapter. This professional BNC extension cable combines one BNC male connector with one female BNC jack and is manufactured with genuine Belden 1505A full-size RG59 75-ohm coaxial cable.
Belden 1505A uses a larger 20 AWG solid-copper center conductor and professional double-shielded construction. It is an excellent choice when you want a more substantial RG59 cable for broadcast, production and installed AV applications.
Every extension cable is hand assembled in the USA, individually inspected and tested for dependable professional video performance.

Extend Your SDI Cable Without a Barrel Adapter
A traditional SDI extension often requires a separate female-to-female BNC barrel coupler between two standard BNC male cables. This extension cable incorporates the female BNC connection directly into the assembly.
Instead of using:
BNC cable → barrel adapter → second BNC cable
You can use:
Existing BNC cable → AV-Cables extension cable → equipment
This reduces the number of separate components and provides a cleaner, more convenient extension connection.

6G-SDI BNC Extension Cable FAQs
How does this extension cable connect?
Connect the female BNC jack to the male BNC connector on your existing cable. Connect the BNC male end of the extension to your compatible SDI equipment.
Do I need a separate BNC barrel adapter?
No. The extension cable has an integrated female BNC jack, eliminating the need for a separate female-to-female barrel adapter.
Does this cable support 6G-SDI?
Yes. Belden 1505A supports SD-SDI, HD-SDI, 3G-SDI and 6G-SDI applications. Maximum distance depends on the video format and complete cable path.
Does this cable support 12G-SDI?
No. Select the Belden 4855R extension cable for single-link 12G-SDI applications.
Why choose Belden 1505A instead of Mini RG59?
Belden 1505A is a full-size RG59 cable with a larger 20 AWG conductor. It is a good choice when a more substantial cable is preferred over the smaller, lighter Mini RG59 construction.
Can every available length support 6G-SDI?
No single distance applies to every video format. Longer options are generally intended for lower-bandwidth SDI formats. Contact AV-Cables for help selecting a cable for critical long-distance applications.
Is the cable directional?
No. This is a passive 75-ohm cable assembly. The connector arrangement determines how it physically connects, but it does not convert or change the video signal.
Where is the cable assembled?
Every cable is hand assembled and individually tested in the USA.
