RG6 VS RG59: Who is the winner?

Coaxial cables, sometimes known as 'coax,' are the most common cables used in video and satellite installations. The RG59  and RG6  cables are two types of cables that can be used for various applications. The biggest difference between the two is the size of the RG6, which is larger than the RG59. The RG6  cable's inner conductor core is thicker, as is the shielding within the rubber sheath.

It's a form of copper wire with a metal shield or other such components. This cable's purpose is to keep interference out of the cable. This cable is mostly used to connect a satellite antenna to a television set. There are several variants of this cable, but we'll focus on the RG6 and RG59 coaxial cables in this post.

RG ratings are used to differentiate between different types of coaxial cables. The acronym   RG  stands for "radio guide," a long-forgotten military word. The number identifies the various cable specifications, however, it is assigned at random, so don't expect any sort of order in the numbers. There have been dozens of coaxial cables developed throughout the years, but the only ones that most people need to worry about are RG  6 and RG  59 cables, so we'll focus on those two types here.

The RG6   cable was created with higher data frequency needs in mind. Because of its bigger conductor, this cable provides greater signal quality. It has a copper center conductor of 18 AWG. Satellite and internet transmissions are compatible with this connection. The thicker dielectric insulation on RG6  coaxial is also present. It has a particular type of shielding that can tolerate signals at Gigahertz frequencies. Both foil and braided shielding  are used in RG6, 

RG59 has been around for a long time. This wire was used to connect televisions. This cable can still be found in most older homes and commercial structures. The copper wire conductor of the RG59  coax cable is 20   AWG. Because this cable has a smaller conductor, it cannot provide the same signal quality as RG6. Its shielding also fails to keep Gigahertz-level signals contained within the cables. This cable became practically obsolete as a result of all of these issues.

The insulation of the RG59  cable is braided. It's made for megahertz interference with lengthy waveforms. Because of this, it's ideal for low-frequency communications. It's suitable for anything with a frequency of less than 50MHz.

1. RG6 cables are made of foil shields and braided aluminum shields.

2. They have better insulation properties.

3. The inner conductor is thicker at the 18 AWG copper center. This helps RG6 cables provide more extended distance proficiency and better bandwidth.

4. The frequency range is better, which means if you are looking for a cable to serve the purpose of a higher frequency range, RG6 is your answer.

5. RG6 cables have low attenuation even though the cables are long.

6. Problems with RG6 come when you need them to work below 50 Mhz. They are not efficient in this case and you will need to use RG59. But these cables work better with frequencies over 50Mhz.

7. Fewer signal loss problems are reported with RG6.

1. RG59 cables are made of 95% copper shields, which helps them block RFI inclusion.

2. Insulation is not as good as RG6 cables.

3. The inner conductor of RG59 cables is a thin – 20 AWG copper center. This makes its diameter smaller than RG6.

4. The frequency range is lower. RG6 can work even with 3Ghz, but RG59 may start showing inefficiency upon touching 2 GHz.

5. If you need to work below 50 Mhz, RG59 is the way to go.

6. RG6 provides lower attenuation when compared to RG59. This is a significant drawback for RG59 cables.

According to the description above, we know that RG6 and RG59 are used for different purposes. Let’s make it in detail.

1.RG6: Satellite DSS applications, CATV

2. RG59: Plasma TV, component video, video projectors, and other baseband video applications, CCTV. One cannot use these cables for satellite feeds because they do not have foil shields.

What is the difference in signal loss between RG6 and RG59 coax cable? The shielding has something to do with signal loss. A cable's shielding can help to ensure optimum signal quality. The better the signal shielding, the less signal interference. Braided Mesh and Foil shielding are the most common types of shielding found in coaxial cables.

Both forms of shielding are used in RG6 cables to prevent signal interference. However, some RG59 cables are only shielded on one side. As a result, RG6 cables often have lesser signal loss than RG59 cables.

Furthermore, signal loss is proportional to transmission distance. The farther the cables are run, the greater signal loss occurs. In comparison to RG59 cables, RG6 cables can transport signals over longer distances while maintaining superior signal quality. As a result, RG6 cables are typically used for high-frequency applications such as television connections, whereas RG59 cables are better suited to low-frequency and short-distance transmission.

As a result, the graphic below might help you better comprehend the topic of coax RG6 versus RG59 on signal loss. It compares the signal loss of RG6 and RG59 at various frequencies.

What is the difference between RG6 and RG59 coax cables? There are messages on the PVC jacket of each coaxial cable if you look closely. It aids in determining whether this is an RG6, RG11, or RG59 coax cable. However, if the type names are overlooked, the cables may not be qualified or professional. These coaxial wires should not be purchased.

Another technique to distinguish between RG6 and RG59 coax cables is to compare their diameters. RG6 has a 6.90mm outer diameter, while RG59 has a 6.15mm outer diameter. Because it has a thicker center conductor, RG6 wire is thicker than RG59 cable. You'll see the difference when you separate the two cords.

RG6 cable has stronger insulation and greater shielding than RG5 cable. It's best for high-bandwidth or high-frequency communications like the Internet, Cable TV, and Satellite TV. If you're not sure which cable to choose, RG6 is the best option.

RG59 cable is thinner and less shielded than RG6 cable. Only low bandwidth and low-frequency applications, such as CCTV installations, are recommended.
