What Type of Coaxial Cable Does Comcast Use? Things to Know

Coaxial Cable

A typical kind of data communication cable is a coaxial cable. Coaxial cables come in a wide variety of styles. But what type of Coaxial Cable does Comcast use?

In hooking up a Comcast cable box, the Comcast manual specifies that you need a 75 ohm coaxial cable with F-type connectors.

What is Coaxial Cable?

Coaxial cable, sometimes known as coax cable, is an electrical cable that transmits radio frequency ((RF) signals from one location to another.

These cables have been a part of technology since the early 20th century, and because of their strength and simplicity of installation, they are primarily used to link satellite antenna facilities to residences and businesses.

How Do Coaxial Cables Work?

The shielded design of coaxial cables makes them a popular option because it enables the center conductor to transmit data quickly while being shielded from harm and interference.

Coaxial cables are mainly built up of these four different layers:

  • 1. A centre conductor which is usually a copper wire, which data and video travels through
  • 2. Surrounding the copper wire is a dielectric plastic insulator
  • 3. A braided mesh made from copper then helps to shield the cable from electromagnetic interference (EMI)
  • 4. The external layer is a plastic coating which protects the internal layers from damage
Coaxial Cable

Data is transmitted through the center conductor of a coaxial cable, and any signal loss (also known as attenuation loss) is stopped and EMI is decreased by the shielding layers that surround it.

Other Considerations

Another thing to consider is the RG value of the coaxial cable—such as “RG-6.” “RG” stands for Radio Guide.

It refers to the diameter and internal features of that specific kind of coaxial cable, and the value that follows it is a measurement of those features. The ideal type of coaxial cable to use with Comcast’s products is not specified by a standard RG value.

What Type of Connector Do We Use for Cable TV Internet?

RJ45 connectors are used for cables like CAT5e and CAT6. These connectors for twisted-pair Ethernet cables resemble standard telephone cord connectors in appearance.

Can I Use Existing Coax Cable for Internet?

Yes, you can use your coax TV wiring to get Internet in your home. In fact, setting up an Ethernet over coax network can ultimately improve your Wi-Fi.

What Connectors Does Xfinity Use?

Xfinity offers broadband and fiber optic Internet services, both of which require a coaxial connection.
