🧠📡 BNC • BNC Splitter

These splitters allow a single BNC signal to be routed to two destinations. They’re passive, compact, and essential for duplicating analog video or RF signals in modular setups. Each variant supports standard 75Ω coaxial transmission and is widely used in CCTV, SDI, and lab-grade signal routing.
 
🔧 Splitter Variants & Use Cases
🔌 1× BNC Male → 2× BNC Female
Use Case: Split a single BNC output to two receiving devices
Devices: DVR → two monitors, or camera → monitor + recorder
Ideal for signal duplication in surveillance or broadcast setups
🔌 1× BNC Female → 2× BNC Female
Use Case: Split a signal from a male BNC cable or port
Devices: RF generator → two analyzers, or video source → dual display
Useful in test benches and coaxial signal routing

🧠 Signal Format Notes
⚙️ BNC: 75Ω coaxial interface for analog video or RF
📡 Passive split—no amplification or buffering
📉 May introduce slight signal loss—best used with short, shielded cables
🔊 No audio—video/RF only
🔁 Compatible with NTSC, PAL, SDI, and RF modulation formats
 
⚠️ Things to Watch Out For
🚫 Not suitable for digital HDMI or Ethernet signals
🔌 Passive splitters may degrade signal—use amplifiers for long runs
🧯 Impedance mismatch can cause reflections or ghosting
📉 Not all devices tolerate split input—verify compatibility
🧪 Always test with known-good cables and endpoints
 
🛠️ Quick Tips for Beginners
🧠 Identify BNC by its twist-lock barrel and single center pin
🔍 Use gold-plated or nickel-plated connectors for better contact
🧲 Choose molded splitters with strain relief for rugged setups
🧼 Clean contacts gently—dust can cause flickering or sync issues
🏷️ Label each leg of the splitter clearly—especially in AV or RF racks
