When working with video distribution or antenna installations, the terms “coax cable” and “TV cable” are often used interchangeably. But are they really the same? This guide explains the structural and functional aspects of these cables, clears common misconceptions, and helps you choose the right cable for your TV or communication project.
Understanding the Basics
What Is a Coaxial Cable?
A coaxial cable (coax) is a type of electrical cable featuring:
- Inner conductor: carries the signal
- Dielectric insulator: maintains spacing and consistency
- Outer conductor or shield: prevents signal leakage and blocks interference
- Protective outer jacket: provides physical protection
Popular coax types include:
- RG6 – commonly used for cable TV and satellite
- RG59 – legacy analog TV and CCTV
- RG58 – 50Ω, used for RF communication (not TV)
What Is a TV Cable?
“TV cable” is a functional term, typically referring to coaxial cables used in:
- Television signal transmission
- Set-top box connections
- Indoor/outdoor antenna systems
Most TV cables are 75Ω impedance, especially RG6 and RG59, which support broadcast frequencies and minimal signal loss.
Are They the Same Thing?
Yes – In Many Cases
TV cables are almost always coaxial cables. The RG6 coax is the de facto standard for modern digital television.
No – Not All Coaxial Cables Are TV Cables
While structurally similar, not every coaxial cable is suitable for TV signal transmission. Factors like impedance, shielding, and frequency range matter.
| Cable Type | Impedance | Common Use | TV Compatible? |
|---|---|---|---|
| RG6 | 75Ω | Cable/Satellite TV | ✅ Yes |
| RG59 | 75Ω | CCTV, Analog TV | ⚠️ Partial |
| RG58 | 50Ω | RF Modules | ❌ No |
Common Misconceptions and Mistakes
Mistake #1: Assuming All Coaxial Cables Are Interchangeable
A mismatch in impedance can lead to:
- Signal reflections
- Quality degradation
- Equipment malfunction
Mistake #2: Judging by Connector Alone
While F-type connectors are common in TV systems, other cables may also use them. Verify impedance and use-case before connecting.
How to Choose the Right Cable for TV Systems
Key Selection Criteria
- Impedance: Must be 75Ω
- Shielding: Dual or quad shielding reduces interference
- Frequency support: Should cover 5 MHz to 1 GHz or more
- Installation factors: Indoor/outdoor rating, flexibility, UV resistance

FAQs – Clarifying the Confusion
Q1: Is RG6 better than RG59 for TV?
A: Yes, RG6 has better shielding and supports higher frequencies.
Q2: Can I use RG58 for my TV antenna?
A: No, RG58 is a 50Ω cable and mismatched for TV systems.
Q3: How do I confirm if a cable is 75Ω?
A: Check specifications printed on the cable or refer to datasheets.
