RG6 vs RG11: Which Coaxial Cable To Buy?


There are different types of coaxial cables on the market. RG6, RG11, and RG59 cable are three of the most common and popular coaxial cable types. RG refers to Radio Guide, which is a designation used to distinguish various coaxial cable types. 


When choosing a coaxial cable, you need to take these factors into account, such as use purpose, cable's conductor size, shielding quality, jacket thickness, cable length, etc. RG6 and RG11 cables are the two coaxial cables widely used in daily life.


RG6 and RG11 cables both have an impedance of 75 ohm. They have similar applications but they are not the same. There are some differences between RG6 and RG11 cable. Do you want to know what type of coaxial cable to buy? Please follow us to explore everything about RG6 vs RG11.

RG6 vs RG11: Applications

RG6 cables are commonly used for telecommunications especially most home applications. They are usually used as TV antennas and TV cables, carrying video and audio signals and data for most indoor high-frequency video devices, such as satellite TV, cable TV, digital TV, smart TV, CCTV, computer, etc. 
RG11 cables can be also used for antennas, TV, Satellite TV, Cable TV. They can do everything that RG6 cables can but they are more used for special purposes like trunk lines, very long runs, straight-line installation, outdoor installation, direct burial, etc. RG11 cables are more commonly used in large places and wide range like broadcast, cinema, theatres, show stage, shopping mall, park, etc

What Do You Use Coaxial Cables For?

RG6 vs RG11: Specification


The construction of RG6 and RG11 cables is the same, and both are mainly made up of 4 parts: Solid Copper/CCA (Copper-Clad Aluminum) Conductor, PE/PVC Dielectric(Insulation) , Shielding(Aluminum Foil+Braided Mesh), and PVC Jacket. However, every component inside RG6 and RG11 cables is different, which results in different specifications and performance.

Want To Buy High-quality Coaxial Cables?
  • RG6 cables provide stable performance when they are transmitting signals for most domestic video equipment. However, RG11 cables cause less attenuation and signal loss than RG6 cables due to the greater thickness of the central conductor and shielding. In sum, RG11 cables bring better signal signal with less fluctuation than RG6 cables.

    Therefore, RG11 cables usually can carry signals of higher frequency and give better signal quality compared to RG6 cables that may suffer from more signal loss and offer poorer signal strength. RG6 cables are particularly suitable for most indoor satellite TV installation. If you are using HDTV at home, RG11 cables should be the best coaxial cable for HDTV.
  • Although RG11 cables offer better signal quality than RG6 cables, they lack flexibility. RG11 cables have larger diameter than RG6 cables. It is difficult to install RG11 cables in small or narrow space in home or office because RG11 cables are much thicker than RG6 cables, making it hard to bend or take sharp turns. RG11 cables can solve distance problem, so they are particularly suitable for outdoor installation, direct burial, and long-distance installation.

    Inversely, RG6 cables are ideal for most indoor installation. Their copper conductor is not as thick as RG11 cables, but the RG6 cable is more flexible to bend and fit in the corners of your house, room, or office. Normally, RG6 cables cannot be buried. It is recommended to use Direct Burial RG6 Coax Cables that are specially designed for burial use because their PVC sheaths are highly water-resistant and heat-resistant.
  • How far can you run RG6 and RG11 cables? RG11 cables have longer range than RG6 cables. The maximum distance limitation for RG11 cables to carry signals is 600m, while for RG6 cables is up to 450m. RG11 cables can run longer distances but still keep strong signal strength, while RG6 cables may suffer from signal loss to some extent.

    Cable length does affect signal quality. The signal needs to travel further in a longer cable, which will cause attenuation. To minimize signal loss, it is better to estimate the cable length that is suitable for your requirement. You can also use an extension adapter or coupler to extend the length of a coaxial cable.
  • RG11 cable price is higher per meter than RG6 cables. The reasons are simple. On the one hand,RG11 cables offer better performance than RG11 cables. On the other hand, RG11 cables use more materials for their thicker conductor, better insulation, and higher-quality shielding than RG6 cables.

What Are Your Requirements On Cables?

RG6 vs RG11: Connector

There are different types of coaxial cable connectors, such as BNC, TNC, and F type connectors. Are RG6 and RG11 connectors the same? The answer is YES! Both RG6 and RG11 cables have an impedance of 75 ohm, so they use the same connector - F type connector. However, RG11 connectors are of bigger sizes than RG6's because R11 cables have larger diameter.

RG6 vs RG11: Which to Choose?

Which is the best coaxial cable? RG6 or RG11? Is RG11 better than RG6? Actually, there is not the model answer to this question and the comparison about RG6 vs RG11. How do you choose the best coaxial cable? Your actual requirements decide you to choose RG6 or RG11 cables. 


For general domestic use and indoor installation, RG6 cables are the best coaxial cables because they are good enough and quite cost-effective. If you are going to use for the trunk lines of large enterprises and buildings, outdoor burial, long-distance installation, outdoor installation, etc, RG11 cables should be more suitable.
