If you’ve ever shopped for TV cabling or worked on a signal distribution project, you’ve probably come across two seemingly similar terms:
“Coaxial cable” and “aerial cable”
Are they the same thing? Can you use one in place of the other? And does it really matter for your signal quality?
In this article, we’ll break down the differences (and similarities) between coaxial cables and aerial cables, helping you avoid confusion, poor signal, or incompatible components—especially in professional television signal and antenna projects.
What Is a Coaxial Cable?
A coaxial cable, or “coax” for short, is a type of signal cable designed for high-frequency transmissions. Its layered structure includes:
- A center conductor (solid copper or copper-clad steel)
- An insulating dielectric
- One or more shielding layers (braid and/or foil)
- An outer protective jacket
This structure allows coaxial cables to:
- Prevent electromagnetic interference (EMI)
- Carry high-frequency RF signals (up to GHz range)
- Be used across various applications: TV, satellite, RF, broadband, CCTV
What Do People Mean by “Aerial Cable”?
Unlike “coaxial cable,” the term “aerial cable” isn’t a technical classification. It’s an application-based name, commonly used—especially in the UK, Australia, and parts of Europe—to refer to:
The cable used to connect a TV aerial (antenna) to a television or receiver.
In practice, most aerial cables are coaxial cables, typically 75-ohm RG6 or similar.
So why the different name?
- “Aerial cable” highlights what the cable is used for
- “Coaxial cable” describes the technical structure
Are Coaxial and Aerial Cables the Same?
Short Answer: Yes, most aerial cables are coaxial cables.
However, not all coaxial cables are suitable aerial cables.
Let’s compare the two:
| Feature | Coaxial Cable | Aerial Cable (TV Use) |
|---|---|---|
| Naming Style | Technical (structure-based) | Application-based |
| Impedance | 50Ω / 75Ω (varies by type) | Always 75Ω |
| Typical Models | RG6, RG59, RG11, LMR400, etc. | RG6 / RG59 (75Ω variants) |
| Usage | TV, CCTV, RF, Internet, etc. | Connecting TV antenna to receiver |
| Weatherproofing | Varies by jacket and shielding | Outdoor aerial cables often weather-rated |
| Connectors | F-type, BNC, SMA, N, IEC, etc. | F-type or IEC (depends on country) |
Can I Use RG6 Coax as an Aerial Cable?
Absolutely. In fact, RG6 is the most recommended cable for aerial use.
Why RG6 Works for Aerial Applications:
- 75Ω impedance: Matches TV tuner and set-top box requirements
- Low attenuation: Supports longer runs without signal degradation
- Shielding options: Foil + braid shielding reduces interference
- Wide compatibility: Works with both analog and digital broadcasts (DVB-T/T2, Freeview, etc.)

Solid copper RG6 from Bafitop is your best choice.
When Might “Aerial Cable” Be Different?
While most aerial cables are coaxial, there are cases where marketing terms or local suppliers use “aerial cable” to refer to:
- Thin, low-quality cables without proper shielding
- Low-cost alternatives with CCA (copper-clad aluminum) instead of solid copper
- Cables that are not UV-resistant or suitable for outdoor exposure
Warning:
Some “aerial cables” on the consumer market:
- May lack true coaxial shielding
- May not support HD broadcast or DVB-T2
- Could suffer from high signal loss over distance
Always check:
- Impedance: Must be 75 ohms
- Shielding: Prefer foil + braid combo
- Conductor: Ideally solid copper for long runs
Choosing the Right Coax Cable for Aerial Use
Here’s a helpful comparison to guide your selection:
| Attribute | Recommended Spec for Aerial Use | Why It Matters |
|---|---|---|
| Impedance | 75Ω | Ensures signal matching |
| Conductor | Solid Copper / CCS | Lower resistance = better signal |
| Shielding | Double (foil + braid) | Protects from nearby EMI sources |
| Jacket Material | UV-resistant PVC / PE (outdoor) | Prevents cracking from sun/weather |
| Connector Type | F-type / IEC-male | Matches TV and set-top box ports |
For satellite TV: Use RG6 Quad-Shield with solid copper
For indoor aerials: RG59 may work for short runs (<10m)

FAQs: Coaxial vs. Aerial Cable
Q1: Is an aerial cable just another name for a coaxial cable?
Yes—most aerial cables are 75Ω coaxial cables used for antenna connections.
Q2: What’s the best coax for aerial signal?
RG6 with double shielding and solid copper is ideal for long-range aerial reception.
Q3: Can I use satellite coax for my TV aerial?
Yes, as long as it’s 75Ω RG6. Satellite coax often has better shielding, which helps.
Q4: What’s the difference between 50Ω and 75Ω coax?
75Ω is for TV/audio/video; 50Ω is for RF/data/radio systems. Don’t mix them.
Conclusion: Same Cable, Different Name—Choose Wisely
To sum up:
- “Aerial cable” is a use-case name
- “Coaxial cable” is a technical name
- For TV antenna systems, RG6 75Ω coax is the right choice
Don’t let naming confusion compromise your system performance. Use standardized, verified coax for long-term signal quality.
