Coaxial cables are important in daily interactions, from internet browsing to TV viewing. These cables come in different types, all designed for a specific application.
Common types include RG-59 and RG-6. We frequently use them in a home setup, although stronger varieties serve industrial and professional needs.
Knowing about these cables can be very helpful, whether we are troubleshooting network problems or setting up new entertainment systems.
What Coaxial Cables Are
They are centre wires often surrounded by wires. Their middle parts carry a signal. Around the cable, you will find a very special material serving as a wall. Then, there are metal shields that keep signals safe.
The outer layer is often plastic to protect other components in the wire. This helps the wire send signals over a long distance without losing quality. You will find coaxial cables behind your TV.
How They Work
Coaxial cables often transmit signals through conductors. You will need a metal shield to ascertain the cable transmits a quality signal. Both get currents simultaneously, which generates magnetic fields. This, in turn, allows signals to remain untouched.
In addition, metal shields protect the signal against electromagnetic interference. Therefore, you can place coaxial cables near other electronics without any problem.
For better performance, the distance between the shield and core should be consistent throughout. Dielectric insulators do this, preventing two signals from coming into contact and cancelling one another.
The outer jacket helps to protect and insulate all the components from damage. Because of that, RF signals will be carried over a long distance with little loss or interference. Based on the application, signals get converted into the following:
- Amplified cell reception
- Images
- Wi-Fi
- Audio
Tips to Choose Coaxial Cables
Investing in the right cable doesn’t just help us achieve reliable connectivity. It also helps to achieve fast and stable internet connectivity. Here are tips that can help you make the right choice:
- Consider Impedance
It refers to the cable’s resistance to electrical current flow. Technically, coaxial cables have an impedance of 75 ohms or 50 ohms. Your choice of impedance depends on the equipment you use and the specific application.
- Look at the Cost & Budget
The prices of coaxial cables significantly vary based on their specifications and quality. Ensure you have a budget that matches your priorities and specific needs.
- Check the Frequency & Transmission Speed
The right cable should support the frequency signal or range that must be transmitted. It must transmit the desired frequency without losing power. Usually, frequency is measured in Hz (hertz) to support various data speeds.
In conclusion, it is not easy to choose a good coaxial cable for our home entertainment systems. This is because we have many brands and specifications out there. It is true that you might be tempted to take shortcuts and go for cheaper cables. However, it is important to invest in quality cables to maintain your home system’s performance.
