What is Coaxial Cable and Uses of Coaxial Cable

Coaxial cable is a type of transmission wire used for high frequency transmission of a signal. Let me explain it in more simple words.


Actually Coaxial Cable is a thick, four layers thick wire, which most of you must have seen while installing TV and setup box.


What is Coaxial Cable and Uses of Coaxial Cable

It is helpful in the connection of cable TV to the setup box, by applying which the quality of the signal coming from the setup box becomes very good. With which you can see the change in any kind of picture quality and the quality of any kind of picture visible in TV increases.

What is Coaxial Cable

RG – 59: Which has an impedance of 75W and is mainly used in cable TV.

RG – 58: Which has an impedance of 50W and is mainly used in thin Ethernet.

RG – 11: Which has an impedance of 50W and is mainly used in thick Ethernet.

Category of Coaxial Cables

Coaxial cables are generally divided into three categories according to Radio Government (RG) ratings.


Uses of Coaxial Cable

As you must have come to know a little bit about the uses of this cable, where it is used in general.

  • To connect most antennas to a TV or digital setup box.
  • To connect the VCR to the TV.
  • For computer's wire connectivity.
  • Security System
  • Shared Cable Network
  • In Digital Telephone Network
  • In Cable TV Network

Types of Coaxial Cable

This cable is mainly of two types, let's know

  • Thiknet Core
  • Thinnet Core

ThikNet Core Coaxial Cable 

The metal insulator core of this cable ie (inner conductor) which is made of copper, its thickness is more. Due to the high thickness of its inner core conductor, there are many differences in it – as its frequency speed is very high and it can transmit its signal easily up to 500 meters.


ThinNet Core Coaxial Cable 

Thinnet core has less thickness of its inner conductor, due to which its frequency speed is very low, it can easily transmit its signal up to about 200 meters.


Advantages of Coaxial Cable

They are used more in high frequency applications.

Their price is quite affordable as compared to others.

EMI (Electric Magnetic Interference) and RFI (Radio Frequency Interference) are very less in this cable.

Its bandwidth is much higher than this cable twisted pair cable.

In this you get to see high transfer rates.

These were some of the benefits that you get if you use Coaxial Cable.


Disadvantages of Coaxial Cable

These cables are heavier than other cables.

This cable is more expensive than twisted pair cable.

Since only one single cable is used in this, so if any kind of problem occurs in this cable then the whole network will come to a standstill.

There is a lot of difference in the safety of this cable, as it can be tangled quite easily, plus you can tamper with it using a T-joint (of BNC type) in between.

It is necessary to ground it in most places to prevent any kind of interference.

These were some of the disadvantages that you may see, if you use Coaxial Cable.
