Coaxial cable is a type of electrical cable that is commonly used for transmitting high-frequency signals. It consists of a central conductor surrounded by a layer of insulation, a metallic shield, and an outer jacket.
The central conductor is usually copper, while the shield is braided copper or aluminum foil. The insulation is typically polyethylene or Teflon, and the outer jacket is made of PVC or other materials.
Coaxial cable is widely used in various applications, including cable television, internet, and telephone systems. It is also used in radio frequency (RF) applications, such as antennas and radio transmitters.
Coaxial cable is preferred over other cables because it provides better shielding against electromagnetic interference (EMI) and radio frequency interference (RFI).
One of the main advantages of coaxial cable is its ability to transmit signals over long distances without significant loss of signal quality. This is because the central conductor is shielded from external interference by the metallic shield.
Coaxial cable is also relatively easy to install and maintain, making it a popular choice for many applications.
There are several types of coaxial cable, each with specific characteristics and applications. For example, RG-6 cable is commonly used for cable television and internet systems, while RG-58 cable is often used in radio frequency applications. Other types of coaxial cable include RG-59, RG-11, and RG-213.

1. What does "coax" mean?
Ans: "Coax" is shorthand for coaxial cable.
2. What is a coaxial cable?
Ans: Coaxial cables send and receive audio/video/data transmissions via electrical signals. They are commonly used for television and internet applications within the telecom/datacom industry.
3. What does "RG" stand for in coaxial cable?
Ans: "RG" stands for Radio Guide, the most common coaxial cable type. RG cables were originally developed for military use during WWII.
4. What is the most common type of coaxial cable used for video signals?
Ans: The most common type of coaxial cable used to carry video signals is RG-62.
5. How do I attach a coax connector?
Ans: To attach a coax connector, you can use a crimp tool for crimp connectors, a compression tool for compression connectors, soldering equipment for solder connectors, or simply twist-on connectors that do not require any special tools.
6. How do I strip the coax cable?
Ans: You can use a coax stripper tool to strip the coax cable.
