Coaxial Cable
A coaxial cable is a specialised cable with a unique design for transmitting high-frequency signals effectively. It is known to be the backbone of modern communication, delivering high-quality signals for television, internet, and a variety of other applications. These cables feature a unique construction that minimises signal loss and interference, ensuring crystal-clear transmission even over long distances.
At RS Australia, we offer a comprehensive selection of coaxial cables to meet your specific needs, including popular types like RG-6 coaxial cable and RG-59 coaxial cable, as well as specialised RF cables for demanding applications.
Types of Coaxial Cables
Coaxial cables come in a wide variety of types, each tailored for specific applications and signal requirements. When choosing a coaxial cable, it's important to consider factors such as impedance, signal type, frequency range, and environmental conditions.
Coaxial Type
Coaxial cables are often categorised by their "RG" rating, a military designation that indicates specific construction and characteristics. Some common coaxial types include:
- RG-6 cable: Widely used for cable television and satellite signals. It has a 75-ohm impedance and is designed for high frequencies.
- RG-59 cable: Typically used for lower frequency applications like CCTV cameras. It has a 75-ohm impedance and is thinner and more flexible than RG-6.
- RG-11 cable: A thicker cable with lower signal loss, suitable for long-distance transmission and outdoor installations.
Connector Type
Coaxial cables can be terminated with various connectors, depending on the application.
Common connector types include:
- F-connector: The most common type used for TV aerial cable and satellite connections.
- BNC connector: Often found in test equipment and professional video applications.
- SMA connector: Used for high-frequency signals in radio and microwave equipment.
- FAKRA connector: Commonly used in automotive applications.
Gender Type
Coaxial connectors come in male and female types. Male connectors have a protruding centre pin, while female connectors have a recessed receptacle for the pin.
Types of Cable Sizes
Coaxial cables are available in different sizes, typically measured by their American Wire Gauge (AWG) rating. Lower AWG numbers indicate thicker coaxial wire with less signal loss. Common sizes include RG-6 (18 AWG), RG-59 (20 or 22 AWG), and RG-11 (14 AWG).
Terminated vs Unterminated
Coaxial cables can be purchased terminated (with connectors pre-installed) or unterminated (without connectors). Terminated cables are convenient for plug-and-play applications, while unterminated cables offer flexibility for custom installations.
Advantages of Coaxial Cables
- Excellent Signal Quality: Coaxial cables provide superior signal shielding, resulting in minimal signal loss and degradation.
- High Bandwidth: They can transmit a wide range of frequencies, making them suitable for various applications like video, audio, and data transmission.
- Durability: Coaxial cables are relatively robust and can withstand harsh environments, making them ideal for outdoor installations.
- Ease of Installation: Many coaxial cables are flexible and easy to install, even in tight spaces.
Applications of Coaxial Cables
Its applications include feedlines connecting radio transmitters and receivers with their antennas, computer network (Internet) connections, digital audio (S/PDIF), and distributing cable television signals. For detailed information about their uses and the different kinds of coaxial cables available, we recommend reading our Coaxial Cable Guide.
Coaxial cables are used in a wide range of industries and applications, including:
- Cable Television (CATV): Coaxial cables are the primary medium for transmitting cable television signals.
- Satellite TV: Satellite dishes use coaxial cables to deliver signals from the dish to the receiver.
- Internet: Many internet service providers (ISPs) use coaxial cables to provide high-speed internet access.
- Radio: Coaxial cables are used to connect antennas, radios, and other equipment in radio stations.
- Aerospace and Military: Coaxial cables are used in various aerospace and military applications due to their reliable signal transmission and durability.
- Coaxial Audio Cable: Used for transmitting high-quality audio signals in professional audio systems.
- RF Cable: Specialised coaxial cables designed for radio frequency applications, including wireless communication and broadcasting.
