Coaxial Cables
About Coaxial Cables
A coax or coaxial cable is a particular type of electrical line that consists of an inner conductor. This conductor has a cover of concentric conduction shield. There is a unique insulating material between these two conductor lines. Many coaxial cables also have a protective outer sheath or a jacket.
The term coaxial refers to the inner conductor and outer shield sharing a geometric axis. These cables carry high-frequency electric signals with loose ends. These cables work in applications like broadband internet, telephone trunk lines, or high-speed computer data busses. Additionally, they are a part of connection radio transmission, cable television signals, and other such types of wired communication mediums. Note that a coaxial cable is different from other cables. Here the dimensions of connectors and cables give precise and constant conductor spacing. This setting is essential for working efficiently as a transmission line.
Types and uses of coaxial cable connectors
Coaxial cables provide a particular type of signal transmission medium. It works to pass electrical signals between two or more components, devices or systems. Whereas standard electrical line consists of more than one wire through which electric current passes. The coaxial cable is ideal for giving radio frequency single as a transverse electromagnetic wave. The internal design of the coaxial cable has a conduction system. It contains additional layers of shielding. Plus, it has an outer protective jacket that prevents damage to the signal carrying components. Commonly coaxial cables work as transmission lines and are capable of transmitting high-frequency signals at lower losses. Here are some common coaxial cable types you can find in the market.
Hardline and flexible coaxial cable
Hardline cables use a central conductor with aluminium, silver, steel or copper. These cables are more prominent in diameter as compared to other types of coaxial cables. They are also helpful in high-strength signal transmission. Some types of hardline wires have pressurized nitrogen. It works as an inhibitor to moisten the intrusion and prevent arching. On the other hand, flexible cables can move and flex to suit the configuration and geometry of a specific application. This cable type uses a metallic inner conductor surrounded by a flexible polymer that works as the dielectric. Loose cables are the most common type across the globe.
Semi-rigid and formable coaxial cable
The semi-rigid coaxial cable has a solid copper outer sheath with PTFE dielectric. Here the copper sheath provides shieling whereas its dielectric properties provide enhanced frequency performance. As they have a semi-rigid design, you can not reform or reflex after the initial forming operation. At the same time, formable coaxial cable is an alternative to semi-rigid cables. These cables use a flexible metal sheath. You can replace and reform these cables by hand to fit any configuration in specialized tools. Formable cables are ideal for layout cable placement in different prototype applications.
Rigid coaxial cable
They consist of two copper tubes that are set concentrically. These tubes have support at fixed intervals across the length of the cable. It comes with the help of PTFE support or disk insulators. These cables are traditionally much flexible and bendable unlike other types of coax outlet cables. These cables are available in flanged straight sections of a specific length. Hence sets of standard connectors or coupling like 45 to 90-degree elbows. They are ideal for joining the different areas of a transmission line.
The twinaxial and triaxial cables
The twinaxial cables have two central conductors. They are fixed in a core with a single outer dielectric. This construction is the opposite of a traditional conductor that we can see in most coaxial cables. These cables offer reduced cable loss with higher protection from ground loops and capacitive fields. On the other hand, the triaxial lines have an extra copper braid that works as a shield. These cables can pass any ground loop current or capacitive field noise away from the inner core.
Tips on how to buy Coaxial Wire online in the UAE
With the growth in cabling beyond traditional tele and video communication, the standardization of coaxial cable has become familiar in offices, homes and all sorts of telecommunication facilities. This diversity in the application has also led to a variety of coax outlets. Hence today we can find a wide range of the best coaxial cables online and in brick and mortar stores. Therefore when it comes to choosing the right type for your needs, important is to question certain specific aspects. Here we are going to share details and hints of the question you should have in your mind and the most suitable answers so that you can get hands-on the best coax cable outlet.
- Know application requirements – Start by finding for what problem you need the cable. You need to assess what qualities of coaxial cable you will need to do the job. Some factors to assess are the frequency range, quality of signals, the power levels of signals, electromagnetic environment and the RF.
- Choose the right impedance – There are mainly two impedances available in the market: 75 Ohm and 50 Ohm. to know this property of the cable, you need to read the product description section on every specific product page.
- Choosing right attenuation vs. length – The attenuation of cable is the measure of loss per unit length. You will need a low power signal cable for long routing. Here we will recommend you to consult some expert prior to searching online or reach customer reviews about suitability for specific needs.
- Cable performance – Once again you will need to consult the customer review section to find about the durability and performance of the product. read customer comments carefully to find if the selected item is reliable for long term use or not.
- Consider branded items – Multimedia items like coaxial cables are actually one-time investments. They take a lot of time in installation and wrong choices can cause havoc at your workplace. Therefore always look for products from reliable and top-rated brands.
- Check the power rating of the cable – You should keep in mind that different cables have different power ratings. you can assess is by looking at the diameter of the cable, the type of centre and outer conductors and power handling capacities. Choose a suitable match for your system needs.
Communication on this date is exclusively dependent on the mediums you are using for transmission. a wrong medium to transmit the power or current can cut you off of the entire world. In commercial and industrial settings this gap is not acceptable at all. therefore it is important to look at the best possible options even if you have to go out of budget.

Are all coaxial cables the same?
There are two main types of coaxial cables. one is with 75 Ohm impedance while another one is with 50 Ohm. Coaxial cables with 75 Ohm are used for video signals whereas 50 Ohm cables are used for data and wireless communications. The two cables cannot be used alternatively.
Are coaxial cables universal?
No, coaxial cables are not universal. However, they are versatile and come in many different types. Each of the available types is made to carry and transmit the specific types of signals from one point to another. Some of the best and most commonly used types of coaxial cables include RFC195 Coax Cable, rg6 cable, rg59 cable, TV coaxial cable and a few more. You can use these different types of cables in television sets, HDTV, for connecting internet-based devices (laptops or desktop computers and servers), for CCTV cameras and any devices that involve video and audio transmission.
What type of coaxial cables does spectrum use?
There are two main types of coaxial cables – ones with an impedance of 75 Ohm (Ω) and ones with an impedance of 50 Ohm.
