Coaxial cables are widely used for transmitting video, radio and data. There are many types of coaxial cables such as RG6, RG59, and RG8. Coaxial cables have one thing in common, and that is their design, which allows for use in a wide range of applications.
Coaxial cable is typically made of an inner copper, sometimes aluminium. It is a twisted strand of wiring that the signals travel on. This wire is housed in a plastic-based sleeve that protects it and keeps the signal from leaking out. Some cable has an additional layer of aluminium covering this sleeve. Over these layers, the entire cable is covered with a thick plastic or rubber outer skin.
Most coaxial cable can be used with computer networks and radio lines, to connect satellite dishes and antennas to televisions, and to connect multiple video devices together. It is also used in telephone communications and security system applications. One of its most common uses is with residential cable TV and cable Internet services.
The design of coaxial cable has multiple effects on the transmission of signals across the cable. For one, the signal is protected from interference from outside sources such as metal objects, electronics and radio signals. This means it can be run right next to other transmission lines and metal. The protective layers also keep the signal from leaking out, which is known as attenuation.
Coaxial cable is flexible. The cable is designed in such a way that it can bend easily. This means it can travel along paths that take it around corners and up and down walls or wire tubes.
Another benefit is its durability. The outer layer protects the wiring inside from weather and the elements. Heavy duty coaxial such as RG8 cable can withstand long-term use in outdoor applications.
The wide range of coaxial cables available on the market means that there is a type for a lot of different applications. Coaxial cable comes in different sizes, different levels of interference/weather protection and different impedance levels. For instance, higher levels work better for video and data signals.
Coax cable can be connected to different types of connectors. The most common is the locking-nut cable-jack connector. The length can reach more than 100 feet before signal loss is noticeable, and the length can be made to meet the user's specifications.
