Best Coaxial Cables That Can Boost Weak Internet Signals

Coaxial cables are the wires that bring internet and cable connectivity to your home. It is a shielded and insulated copper cable that is employed in the connection of computer networks and to deliver cable TV services to customers. The earliest use of coaxial cables was found to be in the 1940s and was used for transmitting both baseband and broadband data communication services. Due to their layered protection, these cables are a good choice for weak signals and they also tend to carry signals at a greater distance. The best coaxial cables can help you transmit data with the least signal loss.

The core of a coaxial cable is made of a core copper wire which acts as the primary channel. The copper wire is enclosed by a braided copper/aluminum sheath which is wrapped by a dielectric plastic insulator. The copper/aluminum sheath protects the cable from external electromagnetic interference. Surrounding the plastic insulator is a Teflon or plastic coating that is used to guard the inner layers from physical damage, such as fire and water. 

There are different types of coaxial cable which vary according to gauge and impedance. Gauge refers to the thickness of the cable and is measured by the radio guide measurement or RG number. The higher the RG number, the thinner the core of the cable. Coaxial cables commonly come in three different sizes including RG-6, RG-11, and RG-59. They are also called RF cables, which stand for “radio frequency”. 

Coaxial cable designed for domestic television should possess an impedance of 75 Ohm. Since HDTV is popular these days, the best coaxial cable for HD viewing is RG-11. RG-11 provides a higher gauge paving way for more space for signals to transfer. This makes the cable more capable of transferring strong HD signals at a higher speed.

RG-6 cable is used to carry signals for internet connections. It has a larger conductor, perfect for carrying high-frequency signals, which provides a much better signal quality. Also, the dielectric insulation is thicker. RG-6 cables are crafted with a different kind of shielding so that they can carry GHz level signals more effectively.

Here are some of the best coaxial cables that can be installed for the internet and your HDTV setup.

Buyer’s Guide

  • Cable Type

Two types of coaxial cables that are considered apt for homes are those with an impedance of 75 Ohms, used for video applications, and those with an impedance of 50 Ω, used for data and wireless communications. If you have needs like uninterrupted movie streaming, live streaming videos, or high-speed internet for gaming then you would be better off with an RG-6 cable. 

  • Type of connector

Commonly three types of connectors are used while connecting coaxial cables, namely, F-type, RCA, and BNC. If you are specifically buying coaxial cable for your TV or WiFi router, it is always recommended to get the cable that has an F-type connector.

  • Build type

Make sure that you buy a cable with layers of aluminum foil or at least braided wires. This will make sure that the wire is properly insulated. It should also have a PVC covering so that the cable can withstand harsh weather conditions.

  • Length

It is always better to not get a cable with a longer length. The longer the coaxial cable, the greater the loss, because the farther a signal travels, it is susceptible to losing more strength. Therefore, determine the distance first and then choose the length of the coaxial cable you want to buy. 

  • Operating Frequency and Transmission

Coaxial cables are built to have operating frequencies that minimize signal loss. The higher the signal’s frequency, the shorter is its wavelength. Therefore, it is more likely that it will escape through the cable’s shields. Most coaxial cables have an operating frequency between 600 and 2000 megahertz (MHz.) 

R6 and R11 cables that feature higher quality have more insulation and operate near 600 MHz. While the lower quality R59 cables which have thinner insulation operate near 2000 MHz. R6 and R11 cables perform better at longer distances than R59 cables. 

FAQs

  • What type of coaxial cable connector is best suited for an internet modem at home?

For an internet modem,  the best connector is F-type. This type of connector is mainly used for increasing the speed of the internet. 

  • Does the length of the coaxial cable affect signal?

Yes as the more the length of the cable the weaker the 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 make up for this loss, you should choose a coaxial cable with more insulation. An RG11 cable with more insulation can lower signal loss over distances of 50 feet or more.

  • Do coaxial splitters reduce signal?

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

  • Does a coax splitter reduce internet speed?

A coaxial splitter will not negatively impact a high-speed internet connection when installed properly.

  • What type of shielding cable should I get?

Shielding of cable makes sure that the signals do not get lost during transmission and the wire is protected from any kind of interference. If you want an in-wall setup, then it is recommended that you get a cable that has a minimum of three layers of shielding. A Coaxial cable with two or three layers of shielding is considered appropriate.

There are a few things to carefully consider before buying a coaxial cable. List down your purpose, the length of wire you want, and your budget before choosing a cable. Hope our review helps you to zero in on the best coaxial cable for your needs.
