Best Coaxial Cable For Internet

Everything You Need To Know About Coaxial Cable for Internet

Coaxial cable has been around for a long time. It is commonly used by internet providers, cable operators, and telephone companies around the world to transmit video, data, and voice communications to customers. It has many singular advantages for accurate, reliable transmission.

Coaxial cable in short is known as Coax cable. It is made up of copper and an aluminum shield with an outer plastic jacket. It has a dielectric insulator that prevents signal loss.

The shield design of a coaxial cable enables it to transmit information quickly, without damage or interference from external factors.

Speaking of coaxial cables, there are three common sizes available. This include:

  • RG6
  • RG59
  • RG11

RG is short for ‘Radio Guide’. The numbers on the right refer to the size of the diameter of the cable.

Coaxial cable has been the first choice of internet providers for a long time. They rely on coax cable because it allows for reliable transmission. A coax internet connection is one of the most common cable connections offered by internet providers.

A coax cable sends a data signal through your coax cable to the modem at your location. The Ethernet connection of the modem helps in transmitting the data and thus provides you with a fast internet connection.

To get a faster internet connection, you must use coaxial cables that are thick. Get the ones that have better shielding and a solid core. A thicker coax cable allows for efficient signal transfer while preventing interferences from external sources.

Using a bad-quality coaxial cable can cause errors and give you a poor connection. It won’t allow you to increase your internet speeds. This is why you should get coax cables rated for 3 GHz as most internet companies use that standard.

Buying Guide For The Best Coaxial Cable for internet

Generally, coaxial cables are better than other shielded cables. They are efficient in transmitting uninterrupted signals from sources to devices. But just like any other product, coax cables are not the same. They have some variations in aspects like the length of the cable, the type of connector used, and the overall performance and functionality.

When it comes to buying coaxial cables, there are a few things you should know beforehand. This will help you pick the right one for yourself.

Here are the things you need to consider when buying coaxial cables:

  • Construction

One of the very first factors to keep in mind is the construction of the coaxial cable. It should have a central conducting cable with a plastic layer surrounding it. The wire mesh surrounding them should insulate the cable and prevent interference. The whole thing should be enclosed in rubber material to provide further insulation.

Having larger rubber jack stems is better as it allows for better insulation. A fine coaxial cable is supposed to be flexible and thin, so it can wrap around obstacles with ease.

The construction of a coax cable defines longevity. If it has a PVC lining and a jack stem made from solid plastic, it will last longer. This is because PVC covering enables the cable to withstand harsh weather conditions. 

  • Length

Coax cables are available in a wide range of lengths, from 3 feet to 100 feet. Of course, you will find longer cables. But you should consider the length of the cable based on what you are going to use it for. In other words, you should always choose the length of the cable according to your needs. You need to determine the length size based on the distance in your office or house where you want to place it.

It is recommended you avoid getting a longer length of cable for a short requirement. That’s because it will weaken the signals and also create a mess. This is why you should first measure the distance and then get the right cable length.

  • Connector Type

When it comes to coaxing cables, there are three types of connectors that you can use. This includes: 

  1. F-type
  2. RCA
  3. BNC

If you want a coax cable for your DVDs, cable boxes, satellite receivers, TVs, or internet modems, it is recommended you get the cable with an F-type connector. This is the most popular type of connector out there. On the other hand, BNC and RCA are used for special purposes.

  • Cable Type

As mentioned above, there are three types of coax cable including RG6, RG11, and RG59. There are no such requirements for getting a special type of coax cable for your home. 

However, if you want a high-speed internet connection for 4K streaming or gaming, then the RG6 type is recommended. Compared to other coax cables, it is better and more efficient in transmitting signals.

  • Design

Coaxial cables have a lot of variance in design. They mainly differ with regard to connector style and color. If you want the best coax cable, you should go for the one that has a gold-plated connector attachment. The copper is braided and oxygen-free which allows you to enjoy the best signal.

For protection against interference and efficient signal transfer, you must look for these features in a cable: a copper-plated outer wall, braided aluminum wire, and a gold-plated connector.

If you want an attractive cable, then go for a high-gloss black cable. Even a dark-blue colored cable will give you a classy touch.

  • Durability

You must also look into the durability of the cable. Whenever buying a coax cable, you need to make sure that it is durable enough. You need to buy a cable that will last you a long time. 

The durability of a cable depends upon the material it is made of. In some cases, the length of the cable can also impact durability. When buying coax cables, go for the ones that are designed to withstand harsh weather conditions. It should be made of high-quality wire material. Also, you should select the length as per your needs. You should keep all of these things in mind to find a durable cable. 

  • Price

You should also consider the price of a coax cable while buying one. The good thing is you will come across coax cables of varying price ranges. But you should pick the one that you can afford.

Before you set out to buy a coax cable, you must determine your budget first. Then look for the options available within your budget. By doing so, you can find the best coaxial cable within your preferred price range. At the same time make sure that the cable has all the necessary features you need.

How do Coaxial Cables Work?

Coaxial cables are mainly popular because of their shielded ability. These cables come with a center copper conductor that enables them to transmit data quickly without damage and interference from external factors.

It works by carrying data in the middle copper conductor wire, while data transmission takes place in the cable. The cable is surrounded by layers of shielding that prevent signal loss.

A coax cable has four different layers including:

  • The central conductor: This mainly consists of copper and is an important component of the cable. This is because the cable helps in transferring video and audio signals.
  • Mesh: The mesh is made of copper and is usually braided. The main function of the mesh is to shield the coax cable from interference.
  • Plastic insulator: It wraps the copper wire and makes dielectric material.
  • Plastic coating: This forms the external layer that helps to protect all internal components of the cable.

Does It Matter What Coaxial Cable I Use for the Internet

Some of you might assume that all coaxial cables are the same, and therefore, you can use any coaxial cable to access the internet. However, that is not true. There exist a few varieties of coaxial cables, and each of them is designed to work in different ways.

Using the wrong coaxial cable can lead to various internet issues such as data loss, slow speeds, and other problems. You need to use a coaxial cable that is ideal for an internet connection.

Coaxial cable is mainly classified into two types when it comes to an internet connection. These include:

  • RG-59

This is an older standard and is no longer suitable for internet connections. Single shielding and a thinner copper core make it more susceptible to signal interference. Using this type of coaxial cable will not give you the desired speed.

If you are using an RG-59 cable, you should upgrade it to the latest standard. This will ensure more efficient performance.

  • RG-6

This is the latest and upgraded version of the RG-59 cable. It comes with double shielding and a thicker copper core. These features help reduce signal interference.

If you want the best internet connection, you should use an RG-6 coaxial cable. It will not only give you stronger signals but also increase the speed of your internet.

Thus, you can see how coaxial cable influences the quality of your internet connection. Choose the right cable, so you can enjoy an uninterrupted internet browsing experience at home or the office.

Types Of Coaxial Cable

Before you go out to buy a coax cable, you must know the different types available. For convenience, we have explained the main types of coaxial cable in the section below.

  • Hard-Line Coaxial Cable

Hardline coaxial cables are one of the strongest cables with a robust outer shield. These coaxial cables can transfer data through long distances with minimal signal loss. The aluminum material provides rigid shielding to the cables. The hardline cable design allows it to transfer huge amounts of data over long distances. They are mainly used in telephones.

  • Semi-Rigid Coaxial Cable

This type of cable comes with a solid outer copper sheath. However, the exterior shield is not as tough as that of the hardline cable. These cables are ideal for advanced data-sharing applications.

  • Flexible Coaxial Cable

This is yet another type of robust coax cable with a flexible outer shield. These cables are designed to withstand stress. They are strong to resist and reduce the loss of data during transmission.

  • Formable Coaxial Cable

The formable cables can be used in place of semi-rigid coaxial cables. These cables are mainly characterized by an optimized tin-soaked shield. This not only protects the cable but also allows for easy installation. These cables are best for outdoor use as they can provide high-quality signals. 

  • Triaxial Cable

These cables are designed with three shielding layers that make them stronger and more reliable. The external shielding helps protect the inner layers from any outer electromagnetic interference. It also prevents the loss of data during transmission.

  • Rigid Coaxial Cable

Rigid coaxial cable has a firm outer copper sheath. They are more rigid than semi-rigid cables and can provide unaltered signals. If you want a substitute for hardline cables, then rigid coaxial cable could be a good option for you.

  • Twin-axial Cable

These cables have a twisted pair covered by a strong shield. They are perfect for transmitting radio signals from your antenna to your receiver.

What are Coaxial Cables Used for?

Coax cables are very common and they are mainly used as transmission lines as they can protect against external signal interference. You can find their use in cables for CATV and other video graphics and broadband applications. The advantage of using a coaxial cable is that it can carry information over a long distance.

It is the basic type of cable used in the television industry and computer networking. That’s because it is less susceptible to interference. Also, it can carry more data than other cables.

Coaxial cables are used for:

  • Video signals
  • TV antenna signals 
  • Digital audio signals

Coaxial cables are available in different impedances. For example, impedances include 93 Ohms and 75 Ohms. Just so you know different impedances have different characteristics. It is impossible to find a coax cable with an impedance higher than 93 Ohms.
