RG6 cables are a common type of coaxial cable. Most people use RG6 coaxial cables to connect various devices in their daily life. But are all RG6 cables the same? Obviously, they are not. There are several types of RG6 coax cables including RG6 Standard, RG6 Tri Shield cable, and RG6 Quad Shield.
RG6 standard, RG6 tri shield, and RG6 quad shield are all coaxial cables. They are all used for satellite TV, CATV, digital TV, Internet, or other high-frequency applications. If you still don’t know their differences, you’ve come to the right page. Let’s look at the differences between these three types: RG6 vs RG6 Tri Shield vs Quad shield.
RG6 standard, RG6 tri shield ,and RG6 quad shield coax cables all have the 18AWG copper wire as the central conductor. And they also have aluminum foil and braided mesh as the shielding. The biggest difference between the three cables lies in the quantity of the shielding. Another key difference between RG6, RG6 Tri Shield and RG6 Quad Shield is the thickness of their insulation and outer jacket.
RG6 standard is the most common type of RG6 cable. It only has two layers of shielding inside the cable. The construction components of RG6 standard include:
1. 18AWG Copper Conductor
2. PVC Dielectric
3. Aluminum Foil
4. Aluminum Braided Mesh
5. Outer Jacket
RG6 tri shield cable, as its name implies, has three layers of shielding. The construction of a RG6 tri shield cable:
1.18AWG Copper Conductor
2. PVC Dielectric
3. Aluminum Foil
4. Aluminum Braided Mesh
5. Aluminum Foil
6. Outer Jacket
RG6 quad shield, sometimes called super shield cable, contains four layers of shielding inside the cable. You can look at its inner construction:
1.18AWG Copper Conductor
2.PVC Dielectric
3.Aluminum Foil
4.Aluminum Braided Mesh
5.Aluminum Foil
6.Aluminum Braided Mesh
7.Outer Jacket

In conclusion, the addition shielding of RG6 tri shield and RG6 quad shield makes them much thicker than RG6 Standard. RG6, RG6 tri shield, or RG6 quad shield, which one to use? It depends on what your actual needs. We will talk about this at the end of the article. Now let’s take a look at the difference of their performance.
How does a coaxial cable work? Generally, a coaxial cable uses the copper conductor to carry electrical power and signals. And the shield is used to protect the transmission from interference and reduce signal losses. Therefore, the more shielding is, the better signal quality will be.
Apparently, RG6 tri shield cables and RG6 quad shield cables have better performance than the RG6 standard. And RG6 quad shield offers the best and most stable performance among the three types. Firstly, RG6 quad shield has more protection against outer interference due to its four layers of shielding. Then, it can deal with much higher frequency and voltage with better and more stable signal transmission.
To select the right cable to use, there are some factors that you need to consider.
1. First of all, you need to check if there is much electromagnetic interference(EMI) surrounding the cables. The main source that causes EMI can be various electrical equipment. If you use a cable with poor performance on resisting interference, you may suffer from signal loss and crosstalk.
2. Then the second issue that you should care about is signal quality. Make sure if you need higher quality signals for your jobs or business. You Some electrical devices require cables that carry signals of high frequency and larger bandwidth.
3. And lastly, the lifespan and the installation of the cable also count. Especially, when you want to use the cable for outdoor applications, you must get the proper type for the installation. There will be environment threats like sunlight and rain that may damage the cable and affect the transmission seriously.
For general home use like satellite TV, CATV, or CCTV, RG6 standard is good enough. On the one hand, the interference is at a normal level, which won’t affect a lot the signal quality. On the other hand, RG6 standard is easy to install inside homes and office. Compared to RG6 tri shield and RG6 quad shield, RG6 standard is relatively flexible because it is not very thick. As you know, RG6 quad shield is sometimes called super shield RG6. That means it can prevent the cable from interference at a highest level. In addition, its thickest insulation and PVC jacket make it a perfect outdoor transmission cable. If you have a large amount of electrical devices to connect, or want to use for outdoor or buried installation, you can directly go for RG6 quad shield.
However, in most cases, it's not recommended to use RG6 quad shield for residential use. As many homeowners prefer DIY cable installation, RG6 quad shield cables are quite expensive and need special connectors. The point is that it is pretty difficult to work with such thick cables on your own. You can easily install them at somewhere that is limited and narrow in your house or office because they really lack flexibility. Some people may not care much about the economical factor and they just fancy the best of everything, and then using RG6 quad shield is without any problem.
However, some special uses do need RG6 tri shield cable and RG6 quad shield cable. Commercial areas like restaurants, shopping malls, offices, or buildings are very typical examples. The extra shielding of RG6 tri shield and RG6 quad shield can resist more interference and reduce signal losses. RG6 tri shield vs quad shield: Which one should you use? It depends on what will you use them for. The biggest difference between RG6 tri shield vs quad shield is the amount of shielding. RG6 quad shield contains 4 layers of shielding. Therefore, if you want to ensure the most stable transmission, you must use RG6 quad shield. Besides, the thickest RG6 quad shield is more durable than the standard and tri shield version. It can prevent interference and reduce crosstalk and noise at a highest level. That's why RG6 quad shield coax cable is also called RG6 super shield coax cable.
You can see the difference of shielding on RG6 Tri Shield Vs Quad Shield:

Does more shielding reduce more signal loss over a longer distance? The answer is no! Many people may think RG6 tri shield cable and RG6 quad shield cable can reduce more signal loss effectively even over long distances than usual RG6 standard. Actually, the loss depends on the size of the central copper conductor and insulation instead of the amount of shielding. The central conductor of RG6, RG6 tri shield, and RG6 quad shield are all 18AWG. The most outstanding performance of the extra shielding is to prevent and resist the interference. If you want your coaxial cables to carry higher-frequency signals, you should go for a coaxial cable with a thicker center conductor. RG11 cable is a typical example.
RG11 cable is different from RG6 tri shield and RG6 quad shield due to its thicker copper conductor. The functions of RG11 cables are similiar to RG6 tri shield and RG6 quad shield in many ways. However, it is a special type of coaxial cable used for longer distances, especially straight-line transmission. The RG11 cable has a thicker central copper wire to carry higher-frequency signals. Due to its larger central copper conductor and thick shielding, RG11 cables can have better and more stable performance over very long runs.
