What Is Coaxial Cable?

 

Coaxial cable, also known as coax cable, is a kind of electric cable used to carry video, audio, and radio frequency signals for different applications like satellite TV, cable TV, CCTV, Internet, etc.

 

Coaxial Cable Construction

A coax cable is mainly made up of four layers - Center Conductor, Dielectric, Shielding, and Outer Jacket. A coaxial cable diagram below can help you understand its construction better.

 1 The center conductor can be made of soild copper or CCA  (copper clad aluminum), carrying data and signal through the cable.

 

 3 The shielding is usually a combination of aluminum foil and braided mesh that helps to prevent electromagnetic interference.

 2 The dielectric/insulation layer is usually made from PVC or PE, surrounding the center conductor.

 

 Coaxial Cable Types

 

Coaxial cables come in different types. RG6 cable, RG59 cable, and RG11 cable are three common coaxial cable types. RG stands for “Radio Guide”, which is the ratings used to identify various coaxial cable types. 

 

Different coaxial cable types have different specifications and applications. Coaxial cable price is also different according to different coaxial cable types. Knowing all coaxial cable types helps you select the right one for your requirements. As a professional coaxial cable manufacturer and wholesaler, New King offers you all coaxial cable types as follow.

 

 

 

RG6 Coaxial Cable

RG6 cable is widely used in various residential and commercial applications but primarily as a TV cable.

RG6 cable is a 75-ohm coaxial cable so it is suitable for most domestic televisions as a TV coaxial cable. 

As one of the best coaxial cable for TV, RG6 cable can transmit high-frequency video and audio signal for satellite TV, cable TV, HDTV, and stereo equipment. 

 

 

 

RG59 Coaxial Cable

RG59 cable has a thinner center conductor than RG6 cable, so it transmits lower-frequency video signals.

RG59 Siamese Cable, also called RG59+2DC  is a popular version of RG59 cable as well as a typical coaxial cable mainly used to carry analog video signals for security cameras. RG59+2DC is a combination of a RG59 coaxial cable plus a power cable that offer direct current to CCTV cameras.

 

 

 

RG11 Coaxial Cable

Among three coaxial cable types, RG11 cable has the thickest center conductor and largest diameter. Therefore, it is often used for special appliactions like outdoor use, direct burial, very long-distance installation, and long straight-line installation for large enterprises and buildings. RG11 coaxial cables carry signals with less signal loss and at a low attenuation level so RG11 coaxial cable price is commonly higher than RG6 cable and RG59 cable.

 

Tri-shield Coaxial Cable

Tri-shield cable, referring to triple shielded cable, is a special form of coaxial cable. Tri-shield cable provides an additional aluminum braided shield between two layers of aluminum foil for a standard coaxial cable. The extra shield adds greater protection against interference like EMI, ensuring a more stable signal transmission. The construction of a tri-shield cable is : Conductor + Dielectric + Aluminum Foil + Aluminum Braided Shield + Aluminum Foil + Jacket. As a professional coaxial cable manufacturer, New King usually offers high-quality RG6 Tri-shield Cable, RG59 Tri-shield Cable, and RG11 Tri-shield Cable.

 

 

Quad Shield Coaxial Cable

Quad shield cable is a special type of coaxial cable as well. Compared to tri-shield cable, it has four shielding layers, which are two sets of aluminum foil and braised shield covering around the standard coaxial cable. The construction of a quad shield coaxial cable is: Conductor + Dielectric + Double (Aluminum Foil & Aluminum Braided Shield) + Jacket. Sometimes the cable is called super-shield cable, as more extra shielding brings much greater performance than the standard coaxial cable, effectively preventing the EMI and reducing signal losses. As a leading coaxial cable manufacturer, New King also offers superior RG6 Quad Shield Cable, RG59 Quad Shield Cable, and RG11 Quad Shield Cable.

 

Coaxial Cable With Messenger Wire

Messenger wire is an additional cable that is bonded to a regular coax cable. It is mainly used to increase the hardness and rigidity to the coaxial cable rather than carrying signals. As an experienced coaxial cable manufacturer, New King offers durable RG6 Messenger Cable(RG6+M) and RG11 Messenger Cable(RG11+M).
