What Are Coaxial Cables and Their Usages?

Coaxial Cable

The best usage of these cables is to transmit data, video and voice communication, and the internet. They are also known as Coax cables. It is a short form of Coaxial cable. They become in use in the early 20th century with diversified advantages. There are different types of coaxial cables available in the market according to their manufacturing structures and designs.

Normally, a coaxial cable comes with an aluminum and copper material inner shielding. The outer jacket of these cables is made of plastic material with a dielectric insulator in it helps in minimizing the signal dropping issue.

These cables are highly in demand from telephone companies and internet providers all around the globe. Their big use is in the homes. Therefore, they become a mandatory part of every home cabling as data transmitting needs increased over time.

As time advances, new cables and technologies are introduced into the market. The cables with new technologies have reduced the value and worth of the coax cables to a great deal as they accompany more options and features. With their old technology and features, they are still highly in demand from the users due to their low cost and high efficiency.  

Key to Success for Coaxial Cables: –

The manufacturing features are the key to success for Coaxial cables. Especially, their inner shielding feature improves its worth and value to a great extent. The copper shielding used inside it allows the cable core to produce a high-data transfer speed without dropping the signals. Hence, this shielding decreases the impact of interference factors on the cable’s performance as well.   

In-demand Coax Cables Sizes: –

The coax cables are available in the market in different sizes. Therefore, users need to select them carefully according to their needs and requirements. The most common sizes that are in demand from the users are these.

  • RG-6
  • RG-11
  • RG-59

The word “RG” stands for “radio guide” or in some cases, as “radio frequency”. Whereas, the number in front of it shows the different variants of coaxial cables. This number represents the diameter of the cable such as 59 means .059 and 11 means .011.  

The RG-6 cable is popular as one of the most non-industrial coax cables among them due to its less thickness. Users prefer to install thicker cables for industrial use like RG-11 as they are more durable and strong in comparison to RG-6 cables. The coax cables used in the homes should possess 75 Ohm impedance for better performance.

Connectors for Coaxial Cables: –

Coaxial cables use different types of connectors. Mostly, F-style connectors are best to use with them but there is a great chance that your system comes with N-type connectors. Further on, there are different types of connectors in the f-style category that are good to use with RG-6 cable.   

  • Compression Connectors
  • Screw-on Connectors
  • Crimp-style Connectors

To make a proper connection of a coax cable with a device, you need the same type of male and female connectors. The male connectors come with a wire coming out from their center whereas, female connectors come with a space in the center where the male connector’s central wire sticks. This makes a proper connection.

Understanding Coaxial Cables Structure: –

The manufacturing design of Coax cables is a little complex for a layman. It comes with different layers of different materials functioning together. Additionally, the inner conductor wire is surrounded by an insulating layer. This insulating material is then further surrounded with shielding materials. The electrical signals flow through the inner conductor wire.

You can check the structure of a coaxial cable below.

1. Central Conductor Wire of Coaxial Cables: –

The central conductor wire of coax cables comprises pure copper or copper-clad steel materials. So, it is sure that it provides high-performance.

2. Center Conductor Bond: –

A material known as stripping polymer is utilized in it. So, this clean stripping polymer layer blocks the moisture. Hence, they remain safe and secure.

3. Dielectric: –

The polyethylene material used in its manufacturing stables the cable mechanically. It comes with closed-cell foam with a high VP value. Consequently, the cable performs well.

4. First Outer Conductor Layer: –

The 1st outer conductor is strongly bonded to the dielectric core. In addition, it is made of Aluminum-polymer tape.

5. Second Outer Conductor Layer: –

This second outer conductor layer is present only in tri-shield and quad-shield coaxial cable variants. It is of Aluminum-polymer tape. Moreover, this layer improves the performance of the cable against interference factors.

6. Third Outer Conductor Layer: –

This layer is also made from Aluminum-polymer-aluminum tape. You find this layer in tri-shield variants of coax cables. This layer improves HF shield isolation before and after flexure.

7. Fourth Outer Conductor Layer: –

You will find this layer only in a quad-shield variant of coax cable. An aluminum braid of almost 34 to 36 AWG utilizes in this fourth outer conductor layer. Hence, this enhances the performance of the cable at locations where interference factors are high.

8. Corrosion Resilient Protection: –

There are two types of materials to make these cable corrosion resilient. One is a non-dripping material designed to stop moisture from entering the cable. On the other hand for underground coax cables, a flowing compound is present in them to seal the small pores in the outer jacket to stop moisture from entering the cable and destroying it. Consequently, it impacts positively on the performance of the cable.

9. Coaxial Cables Jacket: –

A normal coax cable is available in a UV jacket. Whereas, in some cases, they are also available in polyethylene or flame-retardant jackets. These jackets improve the life of a cable and its performance as well.

10. Integral Messenger: –

Additionally, a stimulated, carbon steel wire support attaches to the cable by a separable web. So, it works properly.

Conclusion: –

The performance of the coaxial cables is highly dependent on their structure and the location where they are going to install. Therefore, before buying a coax cable you must understand your needs and requirements properly. Then make a decision that which coax cables suits best to your needs.

At locations, where interference factors are high you must opt for tri-shield or quad-shield cables rather than opting for single-shield or double shield. A tri-shield or quad-shield cable works well against the interference factors and minimizes the signal dropping issues with efficiency.
