Coaxial cables play a critical role in our daily lives, powering various technologies from television to internet services. Among the numerous types of coaxial cables available, RG11 emerges as a notable player. Known for its impressive capabilities and unique characteristics, many users often wonder: What is RG11 coax used for? In this article, we will explore RG11 coax in depth, examining its applications, benefits, and why it remains a popular choice among professionals and DIY enthusiasts.
What is RG11 Coax?
To comprehend the uses of RG11 coax, it is essential to understand what it is made of. RG11 coax is a type of coaxial cable that consists of an inner conductor, surrounded by insulation, a metallic shield, and an outer insulating layer. The “RG” stands for “Radio Guide,” a designation that was originally created by the military to specify the uses of different types of cables. The numbers indicate the specific characteristics of the wire.
RG11 coaxial cable is particularly known for its larger diameter—typically 0.405 inches (10.31 mm)—compared to other coax variants like RG6 or RG59. This structure allows RG11 to deliver superior performance when it comes to both signal transmission and attenuation.
Key Characteristics of RG11 Coax
Several attributes set RG11 apart from other coaxial cables:

What is RG11 coaxial cable and how does it differ from other coaxial cables?
RG11 coaxial cable is a type of coaxial cable that is commonly used in various applications, including video transmission and data networking. It features a thicker diameter compared to RG6 and RG59 coaxial cables, which allows it to carry signals over longer distances with less signal loss. The RG11 cable typically has a characteristic impedance of 75 ohms, making it suitable for applications that require high-frequency signal transmission.
The primary difference between RG11 and other coaxial cables lies in its construction and performance capabilities. The larger diameter of the RG11 cable results in lower attenuation, which is the loss of signal strength as it travels along the cable. Consequently, RG11 is often recommended for longer cable runs, such as between a central distribution point and remote locations, where maintaining signal quality is crucial.
What are the main applications of RG11 coaxial cable?
RG11 coaxial cable is widely used in several applications, primarily in the telecommunications and broadcasting industries. It is commonly employed in cable television installations, satellite systems, and broadband internet connections.
