What is a coaxial cable used for?

Coaxial cables are incredibly versatile and used in a variety of applications needing to transmit radio frequency signals. Here’s a closer look at where you’ll find them in action:

• Television Connections: Coaxial cables are a staple for distributing cable television signals into your home. They ensure that your favourite shows and movies come through with crystal-clear quality.
• Radio Transmitters and Receivers: These cables connect radio transmitters and receivers to their antennas, providing a reliable pathway for radio signals.
• Computer Networks: In networking, coaxial cables (like those used in Ethernet connections) maintain stable and fast data transmission.
• Digital Audio (S/PDIF): For audiophiles, coaxial cables are used to transmit high-quality digital audio signals, ensuring that your sound system delivers top-notch audio fidelity.
• Satellite Communications: They carry signals from satellite dishes to receivers, ensuring the best possible reception for satellite TV and other services.

A standout advantage of coaxial cables is their design, working to confine the electromagnetic field carrying the signal to the space between the inner and outer conductors. With this in place, you can run coaxial cables next to metal objects, like gutters, without worrying about power losses. Plus, their robust shielding protects against external electromagnetic interference, ensuring your signal stays strong and clear.

What is the difference between coaxial cable types?

Choosing the right coaxial cable can make a world of difference in performance. Here’s a quick rundown of the differences:

• RG-6/U: 75 Ohm, used for cable TV, home internet, and general applications. The core size is 1.024 mm.
• RG-8: 50 Ohm, used in audio control rooms, radio stations, and external antennas. The core size is 2.17 mm.
• RG-11: 75 Ohm, ideal for long-distance CATV, HDTV, and video distribution. The core size is 1.67 mm.
• RG-59: 75 Ohm, best for CCTV and low-frequency applications, but not suitable for long runs. The core size is 0.64 mm.

For more advanced needs, LMR® coaxial cables provide enhanced flexibility and lower loss:

• LMR®200: 50 Ohm, outdoor-rated, ideal for short antenna feeder runs.
• LMR®240: 50 Ohm, great for GPS and WLAN applications.
• LMR®400: 50 Ohm, perfect for wireless communications and antenna feeder runs, replacing RG-8.
• LMR®600: 50 Ohm, designed for outdoor use with better flexibility.
• LMR®900/1700: Larger cables for medium antenna feeder runs and low-loss applications.

Each type has its own strengths, tailored to different impedance, core size, and attenuation needs.

Do I need a coaxial cable for TV?

If you’re setting up cable or satellite TV, you will need a coaxial cable. It’s the conduit that carries the video and audio signals from your service provider to your TV, ensuring you get a clear and uninterrupted picture. Even with all the wireless tech out there, when it comes to TV, coaxial cables are still a necessity.

What are the advantages and disadvantages of coax cables?

Advantages:

• Shielding: Coaxial cables excel at blocking electromagnetic interference, so your signal stays clear.
• Durability: These cables are tough and can withstand a lot of wear and tear.
• Versatility: They’re suitable for a wide range of uses, from home entertainment to professional audio and video setups.

Disadvantages:

• Thickness and Flexibility: They can be bulky and less flexible, which might be tricky for tight installations.
• Signal Loss Over Distance: While they work great over short distances, signal quality can drop over longer runs.
