Top 7 Applications of Coaxial Cable and Its Advantages and Disadvantages

Do you want to know about the applications of coaxial cable, and the advantages and disadvantages of coaxial cable? If so then there is nothing to worry about. In this article, you will get all the information about the applications, advantages, disadvantages and other information about coaxial cable. After reading this you will not need to go to any other site.

Coaxial cables were commonly used in early computer networks. As new and advanced Ethernet cables started becoming available in the market, the usefulness of this coaxial cable started decreasing. But even today it is used in cable television connection or DTH connection and broadband internet connection.

What Is Coaxial Cable?

Coaxial cable in computer networks is also often referred to as coax cable. It is a cylindrical-shaped electrical cable with layered construction. It is widely used for transmitting radio frequency signals, including data transmission. The term “coaxial” refers to the presence of two concentric conductors – that is, an inner conductor and an outer conductor – sharing a common axis.

The central core of a coaxial cable is usually made of copper. It acts as a primary conductor to transmit electrical signals. Around this inner conductor there is an insulator layer made of metal such as plastic or foam. This layer separates the inner conductors from the outer conductors, simultaneously preventing signal leakage and maintaining signal integrity.

The insulation layer is followed by a metal shield, often made of mesh or foil. It is known as an outer conductor. This shield provides grounding and shielding against external electromagnetic interference (EMI). There is an insulator layer on top of this outer conductor which protects it from external effects.

The cable is covered with a plastic cover on its outer parts. This plastic cover provides protection and insulation to the cable from physical damage.

Coaxial cables are used for a variety of purposes, including cable television systems, broadband Internet connections, networking, audio/video transmission, and more. Because of the way they are built, they can transmit signals farther while experiencing less interference and signal loss.

While coaxial cables were historically prevalent in networking, they have been partially replaced by other technologies, such as twisted pair cables and fiber optics, in modern data communication networks.

Now You all must know about what is coaxial cable and its structure. So let us know about some applications of coaxial cable.

Applications of Coaxial Cable

Due to the unique characteristics of coaxial cable, it is capable of transmitting signals over long distances while preserving signal integrity. Therefore, the applications of coaxial cable spans a wide range of industries. Some common application of coaxial cable are given below. Let’s talk about it.

Cable Television

Coaxial cables are widely used in cable television systems to transmit signals from the cable provider’s DTH antenna to the customer’s television. Due to the outer shield protecting the inner conductors of this cable well, it delivers the television signal well without any interference.

Broadband Internet Connections

Broadband internet connection

In some places, coaxial cable is used for broadband Internet connections. This is especially done in cable internet services. This is because they facilitate the transmission of high-speed data between the Internet Service Provider (ISP) and the customer’s modem. But nowadays, its use has started decreasing due to the advent of fiber optic cable which provides more speed than coaxial cable.

Closed-circuit television (CCTV)


Coaxial cables are commonly used in Closed-Circuit Television (CCTV) systems for transmitting video signals from surveillance cameras to monitoring and recording equipment. The specific type of coaxial cable often used in CCTV applications is referred to as “RG-59” or “RG-6” coaxial cable.

CCTV cameras often produce high-resolution video signals. Coaxial cables, especially RG-6, have a higher bandwidth capacity, allowing them to accommodate the large amounts of data associated with high-quality video transmissions. These coaxial cables are suitable for transmitting video signals over relatively long distances without significant signal degradation.



Coaxial cables are essential in broadcast applications because they provide a dependable and efficient means of transmitting audio and video signals over long distances. Television Broadcasting, Radio Broadcasting, Mobile Broadcasting, Live Event Broadcasting and Distribution Networks Broadcasting are done using this cable.

Medical Applications

Coaxial cables are used in medical imaging applications to transmit signals between imaging equipment and display devices. The shielding properties of coaxial cables help transmit high-quality signals without any interference in critical medical environments.

Satellite communications

Satellite communications

In satellite communication systems signals are transmitted between ground-based equipment and satellite communication stations using coaxial cables. Its ability to handle higher frequencies is beneficial in satellite communications applications.

Military and Defense

Electronic warfare equipment, radar systems, communications systems, and other defence-related applications all use coaxial cables. Its durability and ability make it suitable for military applications.

Advantages and Disadvantages of Coaxial Cable

This coaxial cable is used in some places and not in others. This shows that this cable has some advantages and some disadvantages. So, let’s go about that.

Advantages of Coaxial Cable

  • The coaxial cable supports high bandwidth, so large amounts of data can be transmitted at high speeds.
  • The design of coaxial cables with inner conductors surrounded by insulators and shielding layers maintains signal integrity by reducing electromagnetic interference.
  • It is cheaper than other Ethernet cables.
  • Coaxial cables are strong and resistant to physical stress. This is because the layers surrounding it are strong.
  • Coaxial cables are relatively easy to install.

Disadvantages of Coaxial Cable

  • Coaxial cables are thicker and bulkier compared to Ethernet cables.
  • It can transmit data only over a limited distance.
  • Twisted pair cable has proven to be better for internet connection than coaxial cable. It is easy to install and cost-effective. Therefore, nowadays twisted pair cables are being used more and more for internet connection.
