Why Use a Multi-Channel SDI Snake?
Running several individual SDI cables can create clutter, tangles and identification problems. A custom SDI snake keeps related video lines together in one manageable assembly while maintaining an individual precision coaxial cable for each signal.
Faster Deployment
Deploy and retrieve several SDI connections together instead of handling each cable separately.
Clear Channel Identification
Color-coded breakout cables help technicians identify matching channels quickly at both ends.
Protected Cable Bundle
Expandable braided sleeving helps protect the cable group from tangles and abrasion while maintaining flexibility.
Built for Your System
Choose the channel count and length required for your broadcast, production or professional AV application.
Belden 4855R Mini RG59 Construction
Each channel is constructed with genuine Belden 4855R Mini RG59 precision video coax. Its compact approximately 4.5 mm outside diameter helps keep the completed multi-channel assembly lighter and more manageable than snakes built with full-size RG59 or RG6 coax.
Belden 4855R supports professional 12G-SDI video while providing the compact construction needed for equipment racks, fly packs, mobile production systems and portable broadcast installations.

Frequently Asked Questions
What does the channel-count option mean?
Each channel is one independent 75-ohm BNC-to-BNC SDI cable. A six-channel snake, for example, carries six separate SDI video signals.
Can this snake carry 4K UHD video?
Yes. Each Belden 4855R channel supports 12G-SDI and single-link 4K UHD video within appropriate transmission distances.
Are all channels tested?
Yes. Every completed channel is individually tested before the snake assembly is approved for shipment.
Can AV-Cables build a configuration not shown?
Yes. Contact us about custom channel counts, lengths, fan-outs, labeling, cable colors and alternative connector configurations.
