RG11 Coaxial Cables
RG11 coaxial cables carry signals over longer distances than any other coax type on the market, with lower attenuation than RG6 or RG59 at the same length. Discounted Cables stocks RG11 cable in riser (CMR) and plenum (CMP) jackets, built on 14 AWG copper-clad steel conductors with dual and quad aluminum shielding for CATV trunk lines, satellite feeds, and commercial broadband distribution. Every order ships tax-free across the USA, so the price you see is the price you pay.
What Makes RG11 Coax Cable Different
RG11 cable uses a thicker 14 AWG center conductor than RG6 (18 AWG) or RG59 (20 AWG), which cuts signal loss dramatically over long runs. The larger conductor and denser shielding result in attenuation of roughly 1.5-2.5 dB per 100 meters at 5 MHz and remain usable out to 3.0 GHz, depending on the shield configuration.
Key specs across our RG11 coax cable line:
-
Conductor: 14 AWG solid copper-clad steel (CCS)
-
Impedance: 75 ohms, standard for CATV and broadband
-
Shielding: 60% aluminum braid with bonded foil (dual shield), or a quad-shield build combining foil and braid layers for tougher RF rejection
-
Dielectric: Foam polyethylene or FEP, depending on jacket type
-
Frequency: Swept and tested to 3.0 GHz
-
Jacket options: CMR (riser-rated PVC) for vertical in-building runs, and CMP (plenum-rated) for air-handling spaces where fire code applies
-
Reel length: 1000 ft, with a nominal weight between 63 and 64 lbs. per reel
Every RG11 cable roll we sell carries an ETL listing through Intertek and meets SCTE IPS-SP-001, UL 444, UL 1655, UL 13, and RoHS compliance. Plenum-rated stock also meets NEC requirements for installation inside air plenums, which matters if your local fire code calls for it.
Where RG11 Cable Gets Used
Because it holds signal strength over longer runs, RG11 coax cable shows up wherever distance or interference resistance matters more than flexibility:
-
CATV trunk and backbone wiring in apartment buildings, hotels, and multi-dwelling units
-
Distribution runs from a rooftop dish or building entry point to a signal amplifier
-
Campus and multi-building broadband backbones, where RG11 handles the long haul and shorter drops switch to RG6
-
Satellite feed lines that exceed the practical range of standard coax
-
Commercial security camera and CCTV backbone runs where the distance from camera to head-end goes past what RG6 can support without a booster
A commercial RG11 cable install typically stays on the backbone segment. Individual room or unit drops still call for a thinner, more flexible cable once the signal reaches its final stretch.
Jacket and Shielding Options
You select the right RG11 cable for your installation:
-
PVC Jacket: For standard indoor use.
-
PE Jacket: For outdoor or direct burial, offering UV and moisture resistance.
-
CMR (Riser) Rated: For vertical runs between floors.
-
CMP (Plenum) Rated: For air-handling spaces that meet strict fire codes.
-
Dual/Quad Shield: For environments with high electromagnetic interference.
RG11 vs. RG6 vs. RG59
All three share a 75 Ohm impedance and F-type connector compatibility, but they serve different jobs. If your run stays under roughly 150-200 feet for standard cable TV frequencies, our RG6 coaxial cable line covers it at a lower cost and with far easier handling. For short CCTV or composite video runs, RG59 cables remain the lighter, more economical pick. RG11 earns its place when a run exceeds 400-600 feet or when the installation demands minimal signal degradation, such as trunk lines feeding multiple RG6 drops downstream.

Buy Bulk RG11 Coaxial Cable
Contractors and system integrators who buy RG11 coaxial cable in bulk get a lower per-foot cost and fewer reel changes on long jobs. Each RG11 cable 1000 ft reel here ships ready for pull, with color options in black and white depending on the build. For bulk RG11 coaxial cable orders in the USA across multiple job sites, request a quote, and we'll work out reel counts and freight in advance.
Discounted Cables ships every order tax-free within the USA, and stock moves fast since every listed reel reflects live inventory. Buy RG11 coaxial cable here and get manufacturer-tested specs, verified compliance documentation, and support from a team that knows the difference between a riser job and a plenum job.
FAQs
What's the maximum distance for RG11 coaxial cable?
RG11 typically holds a usable signal for CATV distribution up to 400-600 feet, well beyond the 150-200 foot practical range of RG6, though the exact distance depends on frequency and signal strength at the source.
Can I use RG11 and RG6 on the same run?
Yes. A common setup runs RG11 for the long trunk or backbone segment, then transitions to RG6 for the shorter final drop to a TV, camera, or outlet. Both share 75 Ohm impedance, so there's no mismatch at the connector.
Is RG11 cable good for outdoor or underground installation?
Riser and plenum builds are rated for in-building runs; if your project needs direct burial or extended outdoor exposure, confirm the jacket rating on the specific reel before installation, since not every RG11 build is direct-burial rated.
What connectors work with RG11?
RG11 takes F-type connectors, though the larger cable diameter requires connectors and compression tools sized specifically for RG11 rather than the standard RG6 hardware.
Why does RG11 cost more than RG6?
The thicker 14 AWG conductor, additional shielding layers, and larger jacket use more raw material per foot, which raises production cost. That extra material is also what delivers the lower attenuation over long distances.
