Coaxial Cable: what it is, what it is for, types

What is a Coaxial Cable?

Coaxial cable, commonly known as coax, It is a type of cable used to transmit audio, video and data communication signals.. It is composed of a copper conductive core, surrounded by a dielectric insulator, a conductive mesh or shield to prevent electromagnetic interference and finally, a protective plastic outer cover.

Coaxial Cable Functions

This cable has a wide variety of uses in the home and professional environment. It is essential in the transmission of television signals, both for radio broadcasting and for connection to cable services. Likewise, it is used for connecting to the Internet through broadband networks and in security systems to connect surveillance cameras.

Types of Coaxial Cable

There are various types of coaxial cables, designed to meet specific needs:

• • RG-6: Very common for home cable and satellite television installations due to its higher bandwidth and better insulation.

• • RG-11: Used for long distances or for broadband signals, as it has less signal loss compared to RG-6.

• • RG-59: An economical option for short distances and low frequency applications such as CCTV security cameras.

Considerations when Choosing a Coaxial Cable

When selecting a coaxial cable, you must take into account the distance of the installation, the type of signal to be transmitted and the level of electromagnetic interference in the environment. A cable with better shielding will offer you greater protection against interference, maintaining signal quality.

The Importance of Coaxial Cable

Although wireless technology continues to gain ground, coaxial cable continues to be a pillar in the transmission of high quality signals. Its ability to transmit data efficiently and securely, over long and short distances, ensures that it will remain an essential tool in the world of telecommunications for a long time to come.
