Coaxial cables are important hardware components of many electronic devices. It is crucial in the operation of devices like cell phone boosters because the booster components are connected to one another by coaxial cables. The selection of the right cable type suitable for the type and power of a cell phone booster is an important process.
Since the time it was patented, coaxial cables have been used as a means for delivering electrical signals across distances without much signal loss. Its applications are many including the transmission of cable TV signals, telephonic signals, and cell phone booster signals.
Cables come in various lengths and sizes depending on their particular application and will have an inner and outer core. Both these cores will have a common geometric axis, hence the name co-axial cables. The typical arrangement prevents electromagnetic interference to ensure the reliable transmission of data over long distances.
Coaxial Cable: Construction
The central core of coaxial cable is usually made up of copper-coated steel or single copper wire. It is the central core that carries the high frequency signal. The wire has to be kept at a constant distance from the next layer. To achieve this, a dielectric insulator (mostly plastic) is introduced around the central wire. The insulator layer is wrapped within a metal shield made of aluminum, copper, or some other metal and the duty of the shield is to cancel out external electromagnetic interference.
The final layer made of rubber keeps the whole configuration insulated.
You can use coaxial cables outdoors and indoors but by incorporating a few changes. When used outdoors, the cables should have extra protection from moisture and the sun.
Coaxial Cable: Operation
The signals carried by the coaxial cable passes through the central wire and the metal shield. Both these conductors generate a magnetic field. The insulating layer between the central wire and metal shield prevents the signals from canceling out each other. The layer also protects the cable from external magnetic fields. The signal thus is carried across large distances without significant loss.
Applications Of Coaxial Cables
Here are some common applications of coaxial cables.
Cell Phone Boosters
Cell phone boosters are used to boost attenuated cellular signals in order to facilitate quality cellular communication. Its major components are outdoor antenna, amplifier, and indoor antenna. The outdoor antenna to amplifier and amplifier to indoor antenna connections are established using coaxial cables.
Basic RF Transmission
RF stands for radio frequency and coaxial cables are used to carry RF signals. These signals are generated when AC passes through a conductive material.
Cable TV And Cable Internet
Cable television and cable internet depend on coaxial cables for transmitting signals.
Coaxial cables are available in different types and their selection varies according to the specific application.
