What Are RG6 and RG11?
RG6 and RG11 are both 75Ω coaxial cables designed primarily for video and data transmission. They're used in applications ranging from residential TV to professional broadcast installations.
RG6 – The Industry Standard
RG6 is the most common coaxial cable worldwide. It's used in millions of homes for cable TV, satellite TV, and broadband internet connections. RG6 offers an excellent balance of performance, flexibility, and cost.
RG11 – The Long-Distance Champion
RG11 is a thicker, lower-loss cable designed for long cable runs. It's used in commercial installations, large buildings, and anywhere signals need to travel over 150 feet without degradation.
Construction Differences
The physical differences between RG6 and RG11 are significant and directly impact performance.
| Component | RG6 | RG11 |
|---|---|---|
| Center Conductor | 18 AWG (Copper or CCS) | 14 AWG (Thicker) |
| Dielectric (Insulation) | Foam PE (4.57mm) | Foam PE (7.11mm) |
| Shield | Single, Dual, or Quad | Dual or Quad (Thicker) |
| Outer Jacket | PVC or PE (6.9mm diameter) | PVC or PE (10.3mm diameter) |
| Overall Diameter | ~6.9 mm (0.27 inches) | ~10.3 mm (0.41 inches) |
| Weight per 100ft | ~6 lbs | ~14 lbs |
Key Takeaways
- RG11 is significantly thicker and heavier – Approximately 50% larger in diameter
- RG11 has a thicker center conductor – Lower resistance = less signal loss
- RG11 has more dielectric material – Better insulation and lower capacitance
- RG11 is stiffer and harder to bend – Requires larger bend radius
Performance Comparison
The thicker construction of RG11 directly translates to better performance, especially over longer distances.
Signal Loss (Attenuation) Comparison
| Frequency | RG6 (dB/100ft) | RG11 (dB/100ft) | RG11 Advantage |
|---|---|---|---|
| 50 MHz | 1.8 dB | 1.2 dB | 33% less loss |
| 100 MHz | 2.5 dB | 1.6 dB | 36% less loss |
| 400 MHz | 5.2 dB | 3.3 dB | 37% less loss |
| 750 MHz | 6.8 dB | 4.2 dB | 38% less loss |
| 1 GHz | 8.5 dB | 5.4 dB | 36% less loss |
| 1.5 GHz | 10.5 dB | 6.7 dB | 36% less loss |
| 2 GHz | 12.0 dB | 7.8 dB | 35% less loss |

When to Use RG6
RG6 is the default choice for most installations. Here's when to use it:
Residential Applications
- ? Cable TV (CATV) – Standard for connecting cable boxes and TVs
- ? Satellite TV – Dish to receiver connections (quad shield recommended)
- ? Broadband Internet – Cable modem connections
- ? Home Theater – Video distribution throughout the home
Commercial Applications
- ? Office Buildings – CATV and broadband distribution
- ? CCTV Systems – Video surveillance (runs under 150 feet)
- ? Hotels – In-room TV distribution
- ? Schools – Video distribution for classrooms
When RG6 is the Right Choice
- Cable runs under 150 feet – RG6 performs well up to this distance
- Standard home installations – Most homes never need anything more
- Flexibility is important – RG6 is easier to route through walls
- Budget-conscious projects – RG6 is significantly cheaper
- DIY installations – Easier to handle and terminate
When to Use RG11
RG11 is the professional choice for demanding installations. Here's when to use it:
Commercial Applications
- ? Large Buildings – Main distribution lines (risers, trunks)
- ? Hotels & Resorts – Long runs from head-end to guest rooms
- ? Campuses – Between buildings or across large campuses
- ? Satellite Master Antenna TV (SMATV) – Multi-dwelling distribution
Professional Applications
- ? Broadcast Studios – Long video runs
- ? Professional CCTV – Long-distance surveillance
- ? Hospitals – Reliable video distribution
- ? Industrial Facilities – Harsh environment installations
When RG11 is the Right Choice
- Cable runs over 150 feet – RG11's lower loss is essential
- Multiple splitters in the line – Each splitter adds loss; RG11 compensates
- High-frequency signals – RG11 performs better at higher frequencies
- Critical installations – When signal quality is paramount
- Future-proofing – Higher bandwidth capability for future upgrades
Maximum Distance Comparison
The maximum distance for a cable run depends on the frequency and the signal quality required.
Recommended Maximum Distances
| Application | RG6 | RG11 |
|---|---|---|
| Cable TV (CATV) – 50-750 MHz | 150-200 ft | 250-350 ft |
| Satellite TV – 950-2150 MHz | 100-150 ft | 200-300 ft |
| Broadband Internet – 5-1000 MHz | 150-200 ft | 250-350 ft |
| CCTV – 0-30 MHz | 200-300 ft | 400-600 ft |
| HD-SDI – 1.5 Gbps | 100-150 ft | 200-300 ft |
| 3G-SDI – 3 Gbps | 50-100 ft | 150-200 ft |
Calculating Your Needs
To determine which cable you need:
- Measure your cable run – Include all walls, ceilings, and bends
- Add 10-15% for service loops – Always add extra length
- Check your frequency – Higher frequencies require lower loss
- Consider splitters – Each splitter adds 3.5 dB loss per port
- If total loss exceeds acceptable levels – Use RG11 or add an amplifier
Cost Comparison
RG11 is significantly more expensive than RG6. Here's what to expect:
| Item | RG6 | RG11 | Cost Difference |
|---|---|---|---|
| Cable (per 500 ft spool) | ~$80 | ~$200 | 2.5x more |
| Connectors (per piece) | ~$0.50-1.00 | ~$2.00-3.50 | 3-4x more |
| Stripping Tool | ~$15 | ~$40 | 2-3x more |
| Installation Time | Standard | 50-75% more | More expensive |

Frequently Asked Questions (FAQ)
1. What's the main difference between RG6 and RG11?
RG11 has a thicker center conductor (14 AWG vs 18 AWG) and larger overall diameter, which provides lower signal loss over longer distances. RG6 is thinner, more flexible, and less expensive.
2. Can I use RG6 for a 200-foot run?
It depends on the frequency. For cable TV (under 750 MHz), RG6 can work at 200 feet, but you may need an amplifier. For satellite TV (1-2 GHz), RG6 is limited to about 150 feet. RG11 is recommended for runs over 150 feet.
3. Can I use RG11 connectors on RG6 cable?
No. RG11 connectors are larger and won't fit RG6 cable. You must use the correct connector for each cable type.
4. Is RG11 better than RG6?
RG11 performs better over long distances but is overkill for most residential installations. "Better" depends on your specific needs—distance, frequency, and budget.
5. How far can I run RG6 for satellite TV?
For satellite TV (950-2150 MHz), RG6 is typically limited to 100-150 feet. For runs longer than that, use RG11 or add a signal amplifier.
6. How far can I run RG11 for cable TV?
RG11 can handle cable TV signals (50-750 MHz) up to 250-350 feet without significant signal degradation.
7. Is RG11 worth the extra cost?
Yes, for long runs or commercial installations. For standard home installations under 150 feet, RG6 is more cost-effective.
8. Can I run RG11 and RG6 together?
Yes, you can use RG11 for the main trunk line and RG6 for shorter drops. Just use proper connectors and splitters.
9. What connectors do I need for RG11?
You need RG11-specific connectors. F-Type connectors for RG11 have a larger barrel, and BNC connectors for RG11 are also larger.
10. Is RG11 harder to install than RG6?
Yes. RG11 is stiffer, heavier, and requires larger bend radius, larger conduit, and different tools. Installation takes 50-75% longer.
11. Which cable is better for CCTV?
For runs under 200 feet, RG6 is fine. For runs over 200 feet, RG11 provides better video quality with less signal loss.
12. Can RG6 do 4K video?
Yes, RG6 can handle 4K video signals when using proper connectors and short-to-medium runs. For longer runs, RG11 is recommended.
