RG11 cable is a type of coaxial cable known for its low signal loss and long-distance performance, making it a popular choice for high-frequency signal transmission in both residential and commercial applications.
what is rg11 cable used for
If you're building a home network, installing a satellite dish, or wiring a CCTV system, understanding when to use RG11 can help you get the best signal quality and reliability.
What Is RG11 Cable?
RG11 is a 75-ohm coaxial cable with a thicker diameter than other RG cables (like RG6 or RG59). It's designed to carry high-frequency signals such as video, internet, and satellite transmissions over longer distances with less signal loss.
✅ Key Features:
Impedance: 75 ohms
Outer Diameter: ~10.5 mm (thicker than RG6)
Center Conductor: Often solid copper for better performance
Shielding: Quad or dual shielded for noise protection
Frequency Range: Up to 3 GHz (depends on construction)
Low attenuation: Lower dB loss per 100 ft than RG6
What Is RG11 Cable Used For?
📡 1. Long-Distance Satellite and TV Signal Distribution
Ideal for running cable over 100 feet
Used between satellite dish or antenna and receiver
Maintains signal quality where RG6 would lose performance
🌐 2. Cable Internet Connections
In backbone runs from the street tap to the home, RG11 is sometimes used for high-speed DOCSIS 3.0 or 3.1 systems
Used by ISPs to reduce signal drop in long runs before the modem
🎥 3. CCTV and Surveillance Systems
Transmits analog video or HD-SDI signals in large buildings or campuses
Often used between DVR and distant cameras or junction boxes
🏢 4. Structured Wiring in Commercial Buildings
Backbone cable in head-end distribution systems
Used to distribute signals to multiple floors or buildings
RG11 vs RG6: What’s the Difference?
| Feature | RG11 Cable | RG6 Cable |
|---|---|---|
| Diameter | Thicker (~10.5 mm) | Thinner (~6.9 mm) |
| Signal Loss | Lower (better for distance) | Higher over long distances |
| Flexibility | Stiffer, harder to bend | More flexible, easier to run |
| Max Length | Up to 300 ft+ | ~100–150 ft before signal loss |
| Cost | More expensive | More affordable |
Use RG11 when you need long-distance runs with minimal signal loss.
Use RG6 for shorter runs inside homes or buildings.
Installation Tips for RG11
Use RG11-specific connectors (larger than RG6)
Avoid tight bends; maintain a larger bend radius
Consider using signal amplifiers if splitting signals after a long RG11 run
Ensure connectors are properly terminated for best performance
Conclusion
RG11 cable is the go-to coaxial solution when distance matters—ideal for delivering satellite, TV, and internet signals with minimal loss. While bulkier and costlier than RG6, its superior performance over long runs makes it indispensable for many professional and residential wiring setups.
