When installing or upgrading a satellite TV system, one of the most frequent questions we receive is:
Can I use an existing RG59 coaxial cable to connect a satellite dish?
This is a valid concern—especially for those working with older buildings or inherited infrastructure. While RG59 cables may still function in certain cases, satellite systems have specific performance demands that most RG59 cables struggle to meet. In this guide, we’ll explain the technical reasons behind cable compatibility and help you make an informed decision for your satellite installation project.
What Is RG59 Used For?
RG59 is a type of coaxial cable commonly found in older systems. It was designed for low-frequency applications and is typically used for:
- Analog CCTV camera installations
- Analog television signals (VHF/UHF)
- Short-distance video transmission
Key characteristics:
- Thinner center conductor (~0.64mm)
- Limited shielding (often single-layer)
- High signal loss over distance
- Performance optimized below 500 MHz
While it may suffice for low-bandwidth or short-distance setups, RG59 is not designed for high-frequency signals like those from satellite dishes.
What Frequencies Do Satellite Systems Use?
Satellite TV systems rely on high-frequency signals that demand low-loss transmission paths. Typical satellite frequency ranges include:
| Signal Path | Frequency Range |
|---|---|
| LNB to receiver (L-band) | 950 MHz to 2150 MHz |
| Ku-band satellite | 10.7 GHz to 12.75 GHz (converted to L-band) |
| HD / 4K TV systems | High signal-to-noise ratio (SNR) required |
These frequencies require coaxial cables with consistent impedance, superior shielding, and low attenuation. RG59’s electrical limitations make it a poor match for such needs.
Can RG59 Handle Satellite Signals?
Let’s look at signal loss comparison over 100 feet (30.5 meters):
| Frequency (MHz) | RG59 Loss (dB) | RG6 Loss (dB) |
|---|---|---|
| 500 | ~6.0 | ~3.9 |
| 1000 | ~10.3 | ~6.5 |
| 1500 | ~13.5 | ~8.8 |
| 2150 | ~17.0 | ~11.5 |
Conclusion: RG59 suffers from much higher attenuation at satellite frequencies. As a result, signal quality may degrade significantly, especially on long cable runs.
Quick Assessment: Can I Use RG59 for My Satellite Setup?
Ask yourself the following:
- Is your total cable length less than 10 meters?
- Are you using an SD (standard definition) satellite receiver?
- Is the RG59 cable new, undamaged, and properly shielded?
- Are there no additional splitters or connectors?
If you answered “yes” to all the above, RG59 may function in a temporary or low-demand setup. However, it is not recommended for any modern or long-term satellite installation.
RG59 vs RG6 vs RG11: Technical Comparison Table
| Parameter | RG59 | RG6 | RG11 |
|---|---|---|---|
| Core diameter | ~0.64 mm | ~1.02 mm | ~1.63 mm |
| Max frequency | ~500 MHz | ~3 GHz | ~3 GHz |
| Typical use case | CCTV, analog TV | Satellite, HDTV | Long-distance SAT |
| Signal loss (100 ft) | High | Medium | Low |
| Shielding | Single | Dual/Quad | Dual |
| Impedance | 75 Ω | 75 Ω | 75 Ω |
When to Replace RG59 with RG6 or RG11?
You should replace RG59 if:
- You’re installing or upgrading to HD or 4K satellite systems
- The cable run exceeds 10 meters
- There are multiple splitters or junctions in the signal path
- The existing cable shows signs of oxidation, age, or physical damage
RG6 is the industry standard for satellite installations. It offers low loss, good shielding, and is cost-effective.
RG11 is recommended for long cable runs or high-demand commercial systems.

Frequently Asked Questions
Q1: Is RG59 ever acceptable for satellite TV?
Only in very short runs (<10 meters) with low-bandwidth systems. For standard installations, RG6 or better is recommended.
Q2: Can I use adapters to make RG59 compatible?
You can connect RG59 physically, but signal integrity won’t improve. The cable’s characteristics (loss, shielding) remain the same.
Q3: What is the risk of using RG59 for satellite?
Signal degradation, loss of channels, audio-video lag, and long-term reliability issues.
Q4: How do I know which cable my project needs?
