📺 F-Type Coax • Composite RCA Adapter

This adapter converts between F-type coaxial connectors and RCA composite video jacks. It’s used to repurpose coax cable runs for composite video signals, enabling flexible routing between TVs, VCRs, cameras, and analog AV gear.
 
🔌 Adapter Varieties
🔹 F-Type Male → RCA Male
Form: Screw-on coax plug → RCA plug
Use Case: Directly connect coax cable to RCA input
Examples:
Coax wall jack → TV composite input
Surveillance coax → RCA monitor
RF modulator → RCA-equipped display
Note: Both ends plug in—no jacks required
🔸 F-Type Male → RCA Female
Form: Screw-on coax plug → RCA jack
Use Case: Connect coax cable to RCA cable
Examples:
Coax run → RCA cable to VCR
Coax camera → RCA extension
RF modulator → RCA patch cable
Note: RCA cable plugs into adapter
🔸 F-Type Female → RCA Male
Form: Coax jack → RCA plug
Use Case: Connect RCA plug to coax cable
Examples:
RCA output → coax cable to TV
Composite source → coax infrastructure
RCA camera → coax patch panel
Note: Coax cable screws into adapter
🔹 F-Type Female → RCA Female
Form: Coax jack → RCA jack
Use Case: Bridge coax and RCA cables
Examples:
RCA cable → coax cable
Composite signal → coax extension
Embedded AV → legacy coax routing
Note: Both ends accept cables
 
🖥️ Compatible Devices
📼 VCRs, DVD players, RF modulators
📺 CRT TVs, analog monitors
📹 Surveillance cameras, AV baluns
🧪 Embedded boards with RCA output
🏠 Coax wall jacks, legacy AV panels
 
✅ Common Uses
🔄 Convert coax cable runs to composite RCA paths
📺 Connect RCA video sources to coax-equipped TVs
📼 Patch analog AV gear into coax infrastructure
🧰 Extend composite video using existing coax
🧪 Prototype analog video paths in embedded builds
 
🧠 Signal Format
F-Type Coax:
75Ω impedance
Typically RG59 or RG6 cable
Screw-on threaded connector
RCA Composite:
Unbalanced analog video
Yellow jack = video signal
Behavior:
No signal conversion—passive physical adapter
Requires compatible analog video signal
 
⚠️ Things to Watch Out For
🔄 Not for RF signals — composite video only
🧬 No audio support — RCA video only (yellow jack)
📏 Signal degradation — long coax runs may reduce clarity
🎛️ Impedance mismatch — use 75Ω coax for best results
🔊 No power pass-through — not suitable for powered coax lines
 
🛠️ Quick Tips for Beginners
🧠 Use with analog composite video only—not HDMI or RF
⚡ Match male/female ends to your cable setup
🧰 Great for retro AV setups and coax reuse
🎛️ Test signal path before permanent install
🧪 Ideal for embedded builds needing analog video routing
