📺 What Does “CATV” Stand For?
CATV stands for Community Antenna Television or Cable Television. It refers to systems that deliver television signals via coaxial cables rather than traditional over-the-air antennas or satellite.
🔌 What Is a CATV Cable?
A CATV cable is a type of coaxial cable specifically designed for transmitting television signals, video, and broadband internet. It’s widely used in cable TV systems, IPTV, satellite distribution, and RF (radio frequency) applications.
The most common types include:
RG6 – Standard for residential CATV
RG11 – For longer distances or backbone connections
RG59 – Older or lower-frequency installations
🧱 Structure of a CATV Coaxial Cable
A typical CATV cable has the following layers:
Center Conductor – Carries the signal (usually copper or copper-clad steel)
Dielectric Insulator – Keeps signal stable and centered
Shielding Layer – Blocks interference (braided aluminum or foil)
Outer Jacket – Protects against weather, abrasion, and UV damage
This coaxial design allows CATV cables to deliver high-frequency signals over long distances with minimal interference or signal loss.
📡 Where Are CATV Cables Used?
CATV cables are used in a variety of residential, commercial, and industrial setups:
Home TV systems
Cable internet services
Satellite dish connections
Closed-circuit television (CCTV)
Multi-unit buildings and hotels
RF modulator systems
📶 Why Use CATV Cable?
✅ Low signal loss over long runs
✅ Shielding reduces electromagnetic interference
✅ Reliable broadband support
✅ Compatible with splitters, amplifiers, and modems
✅ Widely available and affordable
🔍 Common Questions
What’s the difference between RG6 and RG59 CATV cables?
RG6 is thicker and supports higher frequencies and longer runs—best for modern TV and internet.
RG59 is thinner and suited for short-distance analog video, like CCTV.
Can I use CATV cable for the internet?
Yes. CATV cables (especially RG6) are commonly used for cable modems that deliver broadband internet.
Is CATV cable the same as coaxial cable?
Yes and no. CATV cable is a type of coaxial cable, but not all coaxial cables are rated or optimized for CATV applications.
✅ Conclusion: CATV Cable = Reliable Signal Transmission
CATV cables are essential for modern video and broadband systems. They are specially designed to carry high-frequency signals with minimal interference, making them ideal for everything from home entertainment setups to commercial TV distribution networks.
