🧠📡 BNC • BNC Cable

This cable connects two devices with BNC ports, transmitting video, RF, or sync signals over shielded coax. Available in 75Ω (video) and 50Ω (RF/test) variants, it’s used in everything from CCTV to broadcast switchers to oscilloscopes.
 
🔧 Cable Format & Use Case
🔌 BNC Male → BNC Male
BNC plugs into both source and destination devices
Use Case: Transmit analog or digital signal between BNC-equipped gear
Common in SDI video, RF labs, and surveillance systems
 
🖥️ Compatible Devices
📹 CCTV cameras, DVRs, and monitors
📺 SDI switchers, recorders, and broadcast gear
📡 RF generators, analyzers, and modulators
🧠 Oscilloscopes, signal testers, and lab equipment
🛠️ AV racks, patch bays, and coaxial distribution panels
 
✅ Common Uses
🧠 Transmit composite or SDI video between devices
📡 Carry RF signals in test and measurement setups
🛠️ Sync timing signals across lab instruments
🔁 Connect surveillance cameras to recorders or monitors
🧪 Patch coaxial signals in modular AV environments
 
🧠 Signal Format Notes
⚙️ BNC: 75Ω for video (RG59/RG6), 50Ω for RF/test (RG58)
📡 Supports analog composite, SDI (up to 12G), RF, and sync signals
🔁 Shielded coax minimizes EMI and signal loss
📉 Cable length affects signal quality—use RG6 for longer runs
🔊 No audio—video/RF only
 
⚠️ Things to Watch Out For
🚫 Not suitable for HDMI, Ethernet, or audio signals
🔌 Match impedance—don’t mix 50Ω and 75Ω without proper termination
🧯 Poor-quality cables may introduce reflections or ghosting
📉 Tight bends can degrade high-frequency signals
🧪 Always test with known-good endpoints before deployment
 
🛠️ Quick Tips for Beginners
🧠 Identify BNC by its twist-lock barrel and center pin
🔍 Use labeled cables—especially in SDI or RF setups
🧲 Choose molded connectors with strain relief for durability
🧼 Clean contacts gently—dust can cause flickering or sync issues
🏷️ Label both ends clearly—especially in multi-rack environments
