Coaxial Cable vs Ethernet Cable: Which One Do You Need?

In today's connected world, the type of cable you use can make a big difference in the quality, speed, and stability of your connection. Whether you are setting up a home internet network, running security cameras, connecting a smart TV, or building a large-scale office infrastructure, the two most common cable types you will encounter are coaxial cables and Ethernet cables.

Both have been around for decades, but they serve different purposes, come with different advantages, and are suited to different applications. Choosing the right one is essential to ensure optimal performance, cost-effectiveness, and long-term reliability.

Understanding Coaxial Cables

A coaxial cable is a type of data transmission cable that consists of a central copper conductor, surrounded by a layer of insulation, a metallic shield, and an outer protective jacket. This layered design allows coaxial cables to transmit radio frequency (RF) signals with minimal signal loss and strong protection against electromagnetic interference.

Common uses for coaxial cables include:

• Connecting television antennas and cable TV services
• Delivering broadband internet from your internet service provider (ISP) to your modem
• Carrying video signals for CCTV security systems
• Satellite TV and radio connections

Because of their shielding, coaxial cables are well-suited for long-distance runs and outdoor installations. They can maintain signal integrity over longer distances compared to many other cable types, which is why they have been a standard choice for TV and broadband services for decades.

Understanding Ethernet Cables

An Ethernet cable is used to connect devices within a Local Area Network (LAN). Instead of a single conductor like coaxial cables, Ethernet cables use twisted pairs of copper wires to reduce electromagnetic interference.

Common uses for Ethernet cables include:

• Connecting computers to routers, modems, and network switches
• Linking servers in a data center
• Connecting gaming consoles, smart TVs, and streaming devices
• Office networking for high-speed file sharing and video conferencing

Ethernet cables are categorized by their speed and bandwidth capacity:

• Cat5e – Supports up to 1 Gbps, suitable for most home networks
• Cat6 – Supports up to 10 Gbps for short distances, common in modern offices
• Cat6a, Cat7, Cat8 – Higher performance, more shielding, designed for advanced networks

Ethernet connections are known for low latency, high speed, and stable performance, making them the preferred choice for data-intensive applications like online gaming, HD video streaming, and business networks.

Performance Differences

While both coaxial and Ethernet cables can deliver internet access, their performance differs in important ways.

Speed: Ethernet cables, especially Cat6 and above, can deliver speeds up to 10 Gbps over short distances, while coaxial cables typically max out at around 1 Gbps for consumer broadband connections.

Signal Quality: Coaxial cables excel at long-distance transmission without major loss, but Ethernet cables generally provide better stability and lower latency for high-speed local connections.

Interference Resistance: Coaxial cables have excellent shielding, making them less susceptible to external interference, while Ethernet cables rely on twisted pair design to minimize crosstalk between wires.

When to Use Coaxial Cables

You should choose coaxial cables if:

• Your internet service comes from a cable broadband provider (e.g., Comcast, Spectrum)
• You are setting up TV connections or satellite services
• You are installing security camera systems that require coax video transmission
• You need to run cables outdoors or over long distances without losing too much signal

For example, in a typical home broadband setup, your ISP will deliver the signal to your home via coaxial cable, which then connects to a modem.

When to Use Ethernet Cables

You should choose Ethernet cables if:

• You want fast, direct connections for computers, gaming consoles, and smart TVs
• You need stable, low-latency networking for business or remote work
• You are connecting multiple devices in a local network
• You are transferring large files or streaming in 4K or higher resolutions

Ethernet is also the preferred choice for corporate IT infrastructure because it allows precise control over network topology and supports much higher speeds than most coax connections.

Can You Use Both Together?

In many homes and offices, both coaxial and Ethernet cables are used together. For example, a coaxial cable may bring the internet signal from your ISP to your modem, and then an Ethernet cable connects the modem to your computer or router.

If your home is already wired with coaxial outlets, you can use MoCA (Multimedia over Coax Alliance) adapters to transmit Ethernet signals over coax, giving you high-speed wired internet without needing to run new Ethernet cables through walls.

Cost Considerations

Coaxial cables are generally less expensive for basic installations, especially if you only need to connect a single device. Ethernet cables may cost more per meter for higher categories, but they provide future-proof performance and are a better investment for new installations.

However, cost should not be the only factor—you should also consider speed requirements, network reliability, and long-term expansion.

Durability and Maintenance

Coaxial cables are robust, with strong shielding and weather-resistant jackets, making them ideal for outdoor and industrial use. Ethernet cables are more flexible and easier to route indoors, but they may require additional shielding (STP) for use in high-interference environments.
