Coaxial cables are a type of electrical cable consisting of an inner conductor surrounded by a tubular insulating layer, which is further encased by a conductive shielding layer. surrounded by a tubular conducting shield. Coaxial cables are widely known for their durability, ease of installation, and reliable signal transmission over long distances. These cables are used extensively in a variety of applications, such as telecommunications, broadcasting, and networking.

## **How Do Coaxial Cables Work?**

Coaxial cables, also known as coax cables, function by transmitting electrical signals through their central conductor, while the surrounding insulating layer and shield help minimise signal interference. The shielding acts as a barrier to external electromagnetic interference, allowing signals to travel with minimal loss and reduced noise. This combination of insulation and shielding ensures that coaxial cables maintain signal integrity, making them ideal for high-frequency and data-intensive transmissions.

## **Types of Coaxial Cables**

### **RG6 Coaxial Cables**

RG6 coaxial cables are commonly used in television and satellite broadcasting due to their excellent shielding and lower signal loss. With a larger conductor and enhanced insulation, RG6 cables provide superior performance for high-frequency applications and longer cable runs.

### **RG58 Coaxial Cables**

RG58 coaxial cables are typically used for radio frequency (RF) systems and data communications. These cables are characterised by their flexibility and are ideal for use in applications like ham radios, Ethernet networks, and low-power signal transmissions.

### **RG59 Coaxial Cables**

RG59 coaxial cables are widely used for analogue video transmission, such as in CCTV systems. These cables are suitable for short-distance applications, providing effective signal transmission with moderate shielding for video and low-frequency signals.

### **Low-Loss Coaxial Cables**

Low-loss coaxial cables are designed to minimise signal loss, making them ideal for applications where signal strength is critical. These cables are used in situations like outdoor antenna installations, cellular network connections, and high-power RF transmissions, ensuring strong signal performance over long distances.

## **Applications of Coaxial Cables**

### **Television and Satellite Broadcasting**

Coaxial cables are extensively used in television and satellite systems to transmit high-quality audio and video signals. Their ability to reduce interference ensures a reliable viewing experience.

### **Internet and Broadband Connections**

Coaxial cables are used for internet and broadband services, delivering high-speed data to households and businesses. They are commonly used by cable ISPs to provide stable internet connections.

### **Radio Frequency (RF) Systems**

In radio communications, [coaxial cables](https://nz.rs-online.com/web/content/discovery/ideas-and-advice/coaxial-cable-guide) transmit RF signals efficiently while minimising signal loss. They are widely used in applications like ham radios and other wireless communications.

### **Digital Audio Connections**

Coaxial cables can also be used for digital audio transmission, providing high-quality sound for home theatre systems and professional audio setups.

### **Computer Networking**

Coaxial cables are sometimes used in computer networking, particularly in older Ethernet systems (such as 10Base2). While modern networking technologies have evolved, coax cables continue to play a role in specific setups and legacy systems. For detailed information about their uses and the different kinds of coaxial cables available, we recommend you read our comprehensive [Coaxial Cable Guide](https://nz.rs-online.com/web/generalDisplay.html?id=ideas-and-advice/coaxial-cable-guide).
