In addition, we provide you with a thorough purchasing guide that will make the process of finding the right product much simpler for you.

What Is The Use Of Cable Splitter?

It is possible to obtain numerous cable TV or internet connections from a single antenna or modem input by using a cable TV splitter. Depending on your requirements, you may choose from a 2-way, 3-way, 4-way, 6-way, or 8-way cable splitter, among other configurations.

Besides splitting the connection for numerous outputs, it also keeps the signal quality that is received from the internet service provider or cable TV operator intact.

Coaxial Cables Are Available In A Variety Of Configurations

Coaxial cables are classified into three categories: RG59, RG6, and RG11. Aside from being the most commonly used coaxial cable, RG11 and the lower end RG59 are also suitable for a variety of applications.

The following are the fundamentals of each type:

  • RG59 coaxial wire is at the bottom end of the spectrum of coaxial cable choices.

It is suitable for basic TV antenna connections as well as closed-circuit TV hookups requiring a short cable length to function. In order to be an efficient coaxial cable for satellite cable connections or longer lengths, it must have enough insulation.

However, since it is thinner and bends more readily than other types of cable, it is excellent for short connections in confined areas.

  • RG6 cable is more insulated than coaxial cable, resulting in less signal loss over a greater distance.

This makes it an excellent choice for satellite and cable television. Because of its conductivity, RG6 is an excellent choice for high-definition televisions.

  • RG11 coaxial cable will carry the strongest signal for high-definition television, but it is also the thickest available.

Due to its rigidity, it is difficult to bend, and it needs specific connections, making it difficult to install. This is why RG11 is only used for very long lines, such as those needed to link a cable television hookup from the curb to the home. Because of its more durable structure, it is also ideal for burying.

The Things To Keep In Mind When Choosing The Best Coaxial Cable

When searching for a coaxial cable, there are many essential things to consider, including how the cable connects to the television, the cable’s structure, and the frequency at which it operates.

1. Type of Connector

There are two main kinds of connectors: snap-in and snap-out. It is simple to connect and detach BNC connections from TVs, test equipment, and radios. BNC connectors are also known as Bayonet Neill-Councilman.

They are most often used for small wires of varying lengths. They are the most appropriate connectors for RG59 cable in terms of performance. The most popular connections are F-type connectors.

They are used in conjunction with RG6 and RG11 cable to provide connections for cable television, satellite television, and digital television. They are available in two different styles: twist on and crimp. Twist-on connections do not provide a connection of the same high quality as crimp connectors do.

2. Construction

Coaxial cables are composed of three fundamental components:

The conductor, which is made of solid copper or copper-clad steel and is situated in the middle of the cable, is responsible for transmitting the signal from the source to the television.

Solid copper wire has the highest conductivity, but it is stiffer and more difficult to work with. Copper-clad steel may not retain a signal as well as stainless steel, but it is more flexible, making it simpler to work with.

Conductor insulation is provided by a foil shield and copper braiding that surround the conductor and serve as insulation. These materials are essential to the cable’s performance because they shield the cable from electromagnetic interference and radio waves, which may cause signal degradation.

The greater the shielding, the longer the line may be used without losing signal strength and quality. PVC jacket: The last layer of a coaxial cable is a PVC jacket, which protects the cable from water and dirt, enabling it to be used outside without deterioration in performance.

3. Ratings for Power and CL

The CL rating of a coaxial cable specifies which devices may be securely connected to it. Coaxial cables do not provide the same fire danger as television power cables, but it is still essential to examine their fire-resistance ratings (CL).

The majority of coaxial cables have a CL2 or CL3 rating. Cables with a CL2 rating are appropriate for installation within walls and have the ability to resist power surges of up to 150 volts without melting or shorting the conductors.

CL3 is identical to CL2, except it is capable of withstanding surges of up to 300 volts.

4. Frequency of operation and transmission distance

Coaxial cables are intended to operate at frequencies that reduce signal loss to the greatest extent possible. The higher the frequency of the signal, the shorter its wavelength, and the greater the likelihood that it will get through the cable’s shields.

The majority of coaxial cables operate at a frequency ranging between 600 and 2,000 megahertz (MHz.) Greater insulation quality in R6 and R11 cables allows them to function near 600 MHz, whereas lower insulation quality in R59 cables allows them to run near 2,000 MHz.

Higher grade R6 and R11 cables are used for high-speed data transmission. R6 and R11 cables outperform R59 cables over longer lengths because they have a higher conductivity.

5. The relationship between length and attenuation

When a signal from a cable line or antenna travels through a coaxial cable, it experiences attenuation, which is a reduction of signal intensity. Attenuation is produced by a variety of natural characteristics that are intrinsic to the materials used in coaxial cables, such as resistance and dielectric loss, among others.

The larger the length of the coaxial cable, the higher the loss, since the more the distance traveled by a signal, the greater the loss in intensity. In comparison to a 50-foot R6 coaxial wire, a 10-foot R6 coaxial cable will have reduced attenuation.

The frequency of the transmission is another element that influences signal attenuation. The signal attenuation of coaxial cable increases in direct proportion to the frequency at which it works.

For this reason, the quality of RG59, which works at a frequency in the vicinity of 2,020 MHz, is worse than that of RG6, which operates at 600MHz. A 50-foot coaxial cable operating at a frequency of 1,000 MHz will have less attenuation than a 50-foot coaxial cable running at a frequency of 1,500 MHz would have.

6. Application

A coaxial cable may be used to link an external TV antenna to a television set. A cable modem also connects to a cable line, enabling the user to stream video material from the internet (such as Netflix) to a television screen via the use of a cable box.

Coaxial cable may be routed through the walls of a house to enable cable and antenna connections to be made in various rooms. Located outside the home, a coaxial cable may be used to link individual residences to the main cable line serving the area.

A Coaxial Cable Splitter is a device that divides a coaxial cable into two separate cables. Cable splitters take one cable line and divide it into two independent lines by using coaxial cable splitter technology.

A coaxial cable input is located on one side of a tiny box and connects a coaxial cable that runs from the signal source, such as an antenna, satellite, or cable TV line, to the box. In addition, the opposite side of the box has one or two cable inputs that allow the signal to be sent to various devices, such as a television or modem.


Here are some of the best coaxial cables available on the market today, based on the factors mentioned above. They are divided into many categories.
