What is RG6 Coaxial Cable [The Most Detailed Guide]

Coaxial cables have been in use for decades in high-frequency signal transmission applications such as commercial radio and cable television, and they continue to be utilized today.

A kind of electrical copper-based wire cable, coaxial cables were invented by Oliver Heaviside.

They are made up of inner conductors that are separated by a tubular insulating layer and then bundled together by a metallic shield and a synthetic outer jacket, if necessary.

The term “coaxial” refers to the fact that the inner conductor and outer shield are both aligned along the same geometric axis.

What distinguishes these coax cables from other shielded cables is their capacity to serve as transmission lines, which is achieved via the use of regulated cable diameters and consistent conductor spacing.

Coaxial cables are the industry standard for their kind, and they are compatible with the vast majority of everyday electronic devices.

RG-6 Cable is a kind of coaxial cable that is often found in homes and other residential settings, despite the fact that there are just a few different types.

What is Coaxial Cable?

Often referred to as coaxial cable or coax cable, a coaxial cable is an electrical wire used for transmitting radio frequency (RF) signals from one location to another.

Despite the fact that this technology has been available since the early twentieth century, satellite antenna cables are still primarily utilized to link satellite antenna facilities to residences and businesses due to their long lifespan and simplicity of installation.

As a result of the thick, spherical form of the inner insulation layer of coaxial cable, it is easily distinguished from other cables.

Its size distinguishes it from other kinds of cable, such as twisted pair or Ethernet cable, which have a similar appearance.

The most common coaxial cable diameters are RG-6, RG-11, and RG-59 — some of the variations in size are shown in the picture below, while others are not.

In addition to black, brown, and white, coaxial cables are also available in a number of other colors.

It has been a long time since the RG Cable first appeared on the scene, and its importance has grown through time.

The abbreviation RG refers to “Radio Guide,” and it dates back to World War II.

The RG Cable was used for military requirements in the United States since it was initially employed as a unit identifier for bulk radiofrequency.

The cables are associated with numerical values since each kind of coaxial cable had a separate RG rating and had its own set of features and requirements, which explains why the cables are labeled with numbers.

A “U” next to the RG cable designation denoted that the cable was intended for “universal” or broad utility usage.

The numbers associated with RG cables are mostly meaningless in today’s context since they were originally used to provide requirements for the original Radio Guide, which is no longer in use.

In spite of this, certain industry-essential coax cables are still referred to by their original designations, such as the widely used RG-6 cable.

As an industry-standard, this RG option is utilized in a broad variety of consumer applications and is growing more popular.

What is RG6 Coaxial Cable?

RG-6/U coaxial cable is a popular kind of coaxial cable that may be found in a broad range of residential and business settings.

A coaxial cable with a typical impedance of 75 ohms is designated as RG-6/U.

There are several different types of cable designs that fall under the general name “RG-6,” and each has its own set of features that vary from one another, such as shielding properties, center conductor compositions, dielectric types, and jacket types.

The suffix /U denotes that the item is intended for broad utility usage.

The numbers were allocated in a sequential manner.

In accordance with Mil-STD-196E, there is no longer a need for the RG unit indication in the JETDS system, therefore cable supplied today with the RG-6 designation is unlikely to satisfy military requirements.

In reality, the name RG-6 is usually used to refer to coaxial cables having a center conductor of 18 AWG (1.024 mm) and a characteristic impedance of 75 ohms, which is commonly found in coaxial cables.

An In-depth Review About RG-6

The RG-6 is a radio frequency generator.

The RG-6 cable is mainly utilized for the transmission of cable and satellite signals in residential and business applications.

Because it is thin and flexible, it is ideal for wall or ceiling installations, and it continues to be the favored option for transmitting cable television signals.

There is a big conductor in the cable, which improves signal quality.

Additionally, the cable has stronger dielectric insulation, which reduces the likelihood of it carrying harmful electric currents.

Coaxial cable RG-6 has improved shielding, making it more compatible with GHz-level communications and providing greater protection against signal interference.

Bonus: Things To Consider When Buying a Coaxial Cable

Other Considerations When Purchasing a Home

There are many various kinds of shielding and jackets available for each class of cable, and each class of cable may or may not be rated for the installation you have in mind.

RG-6/U

There is also a designation “RG-6/U” that may be seen on RG-6, however, there is no formal designation for the U in this case.

Some believe it means “universal” or “for general utility usage.”

Others believe it means “for broad utility use.”

Another explanation is that it relates to the kind of jacket that the cable is made of, although this is not always the case.

RG-6 and RG-6/U are almost identical in terms of appearance and function.

If you need a certain kind of jacket, be sure to double-check the specifications.

However, we’ll go into the various kinds of jackets later on.

Shielding

Noise interference is prevented from interfering with your signal, and therefore the quality of your signal is preserved when shielding is used.

Coaxial cables are typically shielded with one of two kinds of materials: braid or foil.

The majority of coaxial cables have both of these features (although some RG 59 cables still use single shielding).

In general, the more shielding you have, the better your cable will function, particularly over longer distances.

However, the kind of things that the shields protect varies from one another.

Foil shielding is usually comprised of an aluminum or mylar foil that is attached to the dielectric and placed underneath a metal braid to provide protection.

A highly effective method of guarding against high-frequency electromagnetic interference is to use aluminum foil (EMF).

Braided shielding is a collection of numerous tiny wire strands that are braided around the exterior of a dielectric (and/or foil) to provide electrical resistance.

When it comes to lower-frequency interference, the braid is quite effective.

Copper braid is used in the construction of RG 59 cable, while copper or aluminum braid may be used in the construction of RG 6.

There are “quad shielded” cables available, which contain an additional layer of foil and braid shielding and may provide greater protection than standard cables.

Newer coaxial cables, on the other hand, may utilize a 95 percent braid to perform better while without requiring the additional size and weight of quad shielded cables.

There is a loss of signal.

A small amount of signal loss occurs throughout the length of any cable, despite the fact that shielding methods prevent extraneous signals from interfering with our transmissions.

As an example, consider a 100-foot length of wire with signal loss (attenuation) measured in dB.

Just keep in mind that the longer your cable runs, the greater the likelihood of signal loss you may encounter.

Because of this, it is recommended to limit the duration of your installations to a bare minimum.

Signal loss (in decibels) for RG 59 cables every 100 feet

  • At 50 MHz, the loss is 2.4 dB.
  • Loss at 100 MHz is 3.4 decibels.
  • Loss at 400 MHz is 7.0 decibels.
  • Loss at 900 MHz is 11.1 decibels.
  • 10.8 percent dB of loss at 1000 MHz

Signal loss in RG 6 (measured in decibels per 100 feet)

  • Loss at 50 MHz is 1.5 decibels.
  • Loss at 100 MHz is 2.0 decibels.
  • Loss at 400 MHz is 4.3 decibels.
  • Loss at 900 MHz is 6.8 decibels.
  • Loss at 1000 MHz is 7.0 decibels.
