Best Coaxial Cables of 2025
* We independently evaluate all recommended products and services. If you click on links we provide, we may receive compensation.
Coaxial cables are a type of electrical cable that are commonly used in telecommunications and television industries. They consist of a central conductor wire, surrounded by a layer of insulation, and then a braided shield, which is covered by an outer jacket. The design of coaxial cables allows for the transmission of high-frequency signals with minimal interference or loss of signal quality. They are often used to connect cable TV, internet, and satellite systems, as well as in CCTV and security systems. Coaxial cables are also used in radio frequency and microwave applications, making them an essential component in many different industries.

Frequently Asked Questions (FAQs)
1. What is a coaxial cable used for?
A coaxial cable is primarily used as a transmission line for radio frequency signals. It is commonly used for applications such as connecting radio transmitters and receivers to antennas, computer network connections (e.g., Ethernet), digital audio (S/PDIF), and distributing cable television signals.
2. Is coaxial cable still used for TV?
Yes, coaxial cable is still widely used in the cable television industry and for computer networking. It is preferred over standard telephone wire due to its reduced susceptibility to interference and ability to carry more data.
3. Do I need a coax cable for Xfinity internet?
Yes, in order to have internet service with Xfinity, you will need a coaxial cable to connect the modem. Xfinity can send a technician to install a coaxial outlet if needed.
4. What are the disadvantages of coaxial cables?
Some disadvantages of coaxial cables include their cost, the need for grounding to prevent crosstalk, the bulkiness of multiple layers, and the potential security compromise if the cable is tampered with by hackers.
5. Does a smart TV need a coax cable?
A smart TV only needs a coaxial cable if you want to receive and display signals that are delivered through coaxial cable. There are alternative ways to receive signals, such as via WiFi or by connecting directly to a playback device.
6. How can I get my smart TV to work without cable?
To use a smart TV without cable, you can connect an antenna to receive over-the-air channels or use streaming services by connecting a streaming device to your TV or opting for an all-in-one smart TV solution.
7. What happens if I don't have a coax cable for Xfinity?
If you don't have coax outlets, it doesn't mean you can't have Xfinity cable internet. Comcast may need to perform additional installation steps, similar to cable or satellite TV installation, to provide whole-home internet access.
