Even with a 4K TV, a coaxial cable is necessary to get the best performance. A coaxial cable carries the signal from a satellite, antenna, or cable line to a TV. The wrong one can weaken the signal. Without a good signal, the TV will likely receive an inferior image and frustrating lags while streaming a show.

A coaxial cable is a copper conductor wire surrounded by layers of insulation that protect the line from being disrupted by surrounding radio frequencies and electromagnetic interference. Electrical signal flows through the conductor, carrying video and data to a TV.

This guide will explore what features of a coaxial cable are crucial to making the most out of a home HDTV setup as well as review some of the best coaxial cables on the market.

What to Consider When Choosing the Best Coaxial Cable

There are several important factors to consider when shopping for a coaxial cable, including how the cable connects to TV, cable construction, and operating frequency.

Types of Coaxial Cables

There are three types of coaxial cables: RG59, RG6, and RG11. While RG6 is the most widely used coaxial cable, RG11 and the lower end RG59 are also useful for specific connections. Here are the basics on each type:

  • RG59 is the low end of coaxial cable options. It works for basic TV antenna connections and closed-circuit TV connections with a short cable run. It lacks the insulation to be an effective coaxial cable for satellite cable connections or longer runs. However, because it’s thinner and bends more easily, it’s ideal for short connections in tight spaces.
  • RG6 cable is better insulated, providing less signal loss over a longer distance. This makes it ideal for satellite TV and cable TV. Its conductivity makes RG6 a good option for HDTVs.
  • RG11 will carry the best signal for HDTV but is also the thickest coaxial cable. That makes it difficult to bend and requires special connectors, making it challenging to install. For that reason, RG11 is only used to cover very long runs, such as from the curb to the house for a cable TV connection. Its sturdier construction also makes it suitable for burying.

Connector Type

There are two basic types of connectors:

  • BNC (Bayonet Neill-Councelman) connectors are easy to connect or disconnect to televisions, test instruments, and radios. They are typically used for short cables. They are the most suitable connector for RG59 cable.
  • F-type connectors are the most common. They’re used with RG6 and RG11 cable to make connections for cable TV, satellite TV, and digital TV. They come in two types: twist on and crimp. Twist-on connectors don’t create as high a quality of connection as the crimp style.


Coaxial cables consist of three basic parts:

  • Conductor: A solid copper or copper-clad steel, located in the center of the cable, serves as the conductor that carries the signal from the source to the TV. Solid copper wire provides the best conductivity but is stiffer and harder to use. Copper-clad steel doesn’t hold a signal as well but is more flexible, making it easier to use.
  • Insulation: The conductor is surrounded by a foil shield and copper braids that act as insulation. These materials are a vital part of the cable because they block out electromagnetic interference and radio waves that can cause signal loss. The better the shield, the longer the line can run without signal loss.
  • PVC jacket: The final layer on a coaxial cable is a PVC jacket that protects the cable from water and dirt, allowing it to be used outdoors.

Power & CL Ratings

A CL rating indicates what devices the coaxial cable can safely wire. While coaxial cables don’t present the same fire hazard as a TV’s power cables, it is important to consider their CL ratings. Most coaxial cables have a rating of CL2 or CL3. Cables rated CL2 are suitable for installation inside walls and can withstand power surges up to 150 volts without melting or shorting. CL3 is similar to CL2, but can handle surges up to 300 volts.

Operating Frequency and Transmission

Coaxial cables are designed to have operating frequencies that minimize signal loss. The higher the signal’s frequency, the shorter its wavelength and the more likely it is to escape through the coax cable’s shields. Most coaxial cables have an operating frequency between 600 and 2,000 megahertz (MHz.) Higher quality R6 and R11 cables, which have more insulation, operate near 600 MHz, while lower quality R59 cables, which have thinner insulation, operate near 2,000 MHz. R6 and R11 cables perform better at longer runs than R59 cables.

Length vs. Attenuation

Attenuation is the loss of signal strength that happens when a signal from a cable line or antenna travels along a coaxial cable. Attenuation is caused by a range of natural factors inherent to the coaxial cable’s materials, like resistance and dielectric loss. The longer the coaxial cable, the greater the loss, because the farther a signal must travel, the more strength it will lose.

A 10-foot R6 coaxial cable will have less attenuation than a 50-foot R6 coaxial cable.

Another factor affecting signal attenuation: frequency. The higher the frequency the coaxial cable operates on, the greater the signal attenuation. This is why RG59, which operates at a frequency near 2,000 MHz, is lower quality than RG6, which operates at 600 MHz. A 50-foot coaxial cable with an operating frequency of 1,000 MHz will have less attenuation than a 50-foot coaxial cable operating at 1,500 MHz.


Coaxial cable can connect an external TV antenna to the TV. It also connects high-speed internet from a modem to a cable line, allowing the user to stream content from the web (like Netflix) onto a TV screen. You can run coaxial cable through a home’s walls to allow cable and antenna connections in different rooms. Outside the house, coaxial cable can connect the main cable line in the neighborhood to individual homes.

Coaxial Cable Splitter

Coaxial cable splitters take a single cable line and separate it into two separate lines. On one side of a small box, a coaxial cable input connects a coaxial cable running from the signal source, such as an antenna, satellite, or cable TV line. The other side of the box includes two or more cable outputs, which send the signal to multiple devices, such as a TV or modem.


If you still have questions about which coaxial cable is the best one for your home, here’s more information to help you decide.

Q. Does the length of a coaxial cable affect signal?

Yes. The length will weaken signal strength. A 50-foot cable will experience a noticeable signal loss, while a 100-foot cable can lose as much as a third of its signal. To offset the loss, choose a coaxial cable with more insulation. An RG11 cable with more insulation can reduce signal loss over distances of 50 feet or more.

Q. Do coaxial splitters reduce signal?

Yes. Any time a signal is split, the signal is weakened. To lessen the loss, choose higher quality splitters with gold plating instead of cheaper splitters made of inferior materials.

Q. Does a coax splitter reduce internet speed?

No. A coaxial splitter will not negatively impact a high-speed Internet connection when installed correctly.

Q. How do I choose a coaxial cable?

Select a coaxial cable that best meets your set up. Most RG6 coaxial cable is suitable for sending a quality signal from source to device. If the run between the signal source and the TV is longer than 50 feet, consider using an RG11 cable. If you live in a densely populated area, consider using a coaxial cable with quad shielding to protect your signal from the surrounding interference.
