What is coaxial cable?

Coax cable can transmit radiofrequency signals from source devices to destination devices. Radiofrequency range (RF) is the range that spans the radiofrequency spectrum from the upper end to the lower infrared spectrum (from 200kHz to 300GHz).

Coaxial Speaker Cable refers to the construction and design of the cable. This is because the core (or inner conductor) of the cable and the woven shielding, which are usually made of copper, share the same axis (they’re coaxial).

Although the cable was first introduced in 1858, it was patentable 22 years later in 1880. It has been a common cable in every household since the advent of television and especially since then.

What does it look like?

Coaxial cables are simple in shape. Although their thickness and color can vary and their structure might be more complex or less, all coaxial cables have four key elements. These four elements are:

Conductor core

Dielectric insulator

Metallic shield (usually made of woven copper)

Jacket made of plastic

The core is often made of copper. Commonly, copper-plated steel and stranded Copper are used.

A dielectric insulator surrounds the core conductor. The insulator can be made from solid or foam plastic or air with spacers.

Most shields are made from braided copper wire. Sometimes, it may be a silver-plated braid. Two shields may be used for higher-quality cables – aluminum foil and a braided copper cable. Sometimes there are four layers of shielding: two layers aluminum foil, two layers braided copper wire. Shielding can reduce losses and increase performance. However, it can make the cable thicker, and therefore less flexible. This is not always desirable.

The jacket is the final layer, commonly known as the jacket. It’s typically made from PVC (Polyvinyl Chloride). The jacket can be made from a fire-resistant material or a material that is resistant to oxidation, ultraviolet light, and water.

What are the Advantages and Drawbacks of Coaxial Cables

Coaxial cables are used in radio communications, wi-fi systems and cable TV. There are many reasons coaxial cables are used.

Coaxial cables have the most significant advantage due to their specific design and construction. Coax cables are less vulnerable to radio-frequency and electromagnetic interference due to their shielding and outer jacket. Coax cable construction also allows for high-frequency applications (50MHz and above). Coax cables offer higher bandwidth transmissions and transfer rates than twisted pair cables. Coaxial cables are very affordable, simple to set up and expand, and they can be quite durable.

Different types of coaxial cables

There are many factors that can help you distinguish between coaxial cables: their impedance, their thickness, and their purpose.

There are two types of impedance: those with 50 and 75 impedance.

50-cable radio transmission cables are common because 50 matches many radio transmitter antennas. These cables can also be used to transmit high-frequency digital data over coaxial Ethernet networks.

75-inch cables are more common in households. There’s a good chance that you have a coaxial cable at home. These cables are used in video/audio transmission as well as telecommunications. 75 coaxial cables are used in RF video transmissions and cable TV systems.

What Connectors are Used for Coax Cables

Different types of cables and different applications require different connectors. There are many types of coax connectors available, but the most popular are BNC, SMA connectors and N-type connectors. F-type connectors are also available.

What’s the purpose of coaxial cable?

Coaxial cables can be used in many applications, including radiocommunication systems, telecommunications systems, and wi-fi networks. They are used to transmit audio and video via coaxial cables, such as TV antennas, HDTV, cable TV, internet, and cable TV.

For different purposes, different cable types and connectors can be used. For cable TV, high speed cable internet and satellite TV, the most common cable types are RG-6 and RG-7.
