Imagine what life would be without the good communication devices we enjoy at home and workplace. Passing a message or a document from one point to another would be a tall order and getting teams to achieve their goals would more difficult than we who’ve tasted the information era could ever imagine. We have fast moved into an era where communication has been so simplified and a lot of gadgets have been developed that messaging or making a phone call is just a matter of touching a button.

Reflecting upon the old gone days when you could hardly make a call with ease or send quality videos I bet you agree with me that technology has infused more life into our daily living. With digital TVs, computers and High definition cameras plus other communication gadgets, we call it a well done job, credit due technology.

It is however indispensable to indicate that coaxial cable have been the central player in this breakthrough. This cable is used in the transmission of videos, communications and audio files. Of course for any communication system, any typical electronic cable with high bandwidths and greater transmission capacity would do the job but a highly specialized cable like the coaxial cable is grievously needed, the coaxial cable fits well.

One of the household devices has been the TV, we all can relate the coaxial or coax cables so well with this device. So to say, quite a number people only relate the cable to connecting their TVs however the truth is, its use is not limited to this. The cable is also used in networks and platforms which allow for broadband cable internet connection using devices like cable modem.

Perchance your TV cable is spoilt and you are planning to buy a new one, I can imagine how you really desire to buy another coax cable that shall service you with quality and quantity time. Truth be told, many malicious businesses thrive out there, and guess what? They do well because they earn hugely from customers who are ignorant. I bet you will not fall for their trap if you consider purchasing quality and guaranteed cable products from reliable suppliers like Nassau electrical; an electrical cable shop that provides you with wide variety of quality cable products.

Components of a Coaxial Cable
Typically Coaxial cable is a cable which has several components. In its structural making, there is the inner conductor which is then wrapped all round by a conductive shield. Other types may also have a sturdy jacket which serves as an outer insulation structure. Here is an illustrative diagram which shows in design construction what typically forms the cable. It is through the center conductor where the electrical signal flows.

1.Center conductor – this part is primarily made up of copper-clad steel. As mentioned above, it is through this region that electrical signal is conducted. With utmost high electrical conductivity, probably the best, copper metal is an excellent conductor which makes this cable to be a top-notch signal conductor. High speed network conductivity is vital, who never likes a high speed transfer of data? That is where copper made coaxial cable comes in handy.

2.Center conductor bond – this component plays a very critical role. It is structurally made up of a stripping polymer which is clean and designed to establish a blockage for moisture migration. Moisture if not tamed, can interfere with the quality and efficiency of a cable, it can cause malfunction. The center conductor bond prevents these uncertain occurrences.

3.Dielectric – Mechanical stability is one thing you really need to consider when using a cable. A cable without comprehensive stability may not guarantee the versatility needed in the electrical applications. This component provides the coaxial cable with undoubted mechanical stability. It is made from polyethylene, which is characterized with high mechanical stability

4.First outer conductor – this component is technically, made up of an aluminum-polymer shield. This acts as a tape, securely bonded to the dielectric core. This shield is important for signal safety; it prevents any signal noise and interference.

5.Second outer conductor – this outer conductor consists of an additional tape which is made from aluminum polymer material. This tape applies in construction of both tri-shield and quad-shield. Its importance is to further improve High Frequency shield isolation process when beginning and ending flexure.

6.Third outer conductor - here is another outer conductor which has been designed with aluminum polymer tape. This tape serves in the constructions of both tri- and quad-shields. This third conductor technically helps to enhance High Frequency shield isolation process at the beginning and finishing of flexure.

7.Fourth outer conductor – Here we have the fourth outer conductor which has an additional braid made from either 34 or 36 Awg Al. This braids are applied in constructions of quad-shield. . It is to improve Low Frequency shield isolation in environments with extreme Radio Frequency.

8.Corrosion resistant protection
 i. Indoor and aerial – it is simply a material designed (non-drip material) to eliminate moisture entry into the cable      construction.

 ii.Underground – this is a flowing compound whose objective is to tightly seal small jacket ruptures.

9.Jacket – This is the overall protector. It is a stable outer jacket which prevents UV rays. The jacket is either made of polyethylene (PE) or polyvinyl chloride (PVC) which flame retardant. It is designed to protect the cable at the installation time and in the subsequent life time of the cable on service.

10.Integral messenger – This is a carbon steel wire which is well galvanized and acts as a support member to the main cable. A separable material is used to attach the integral messenger to the main cable.

Thick Cable, Good Cable
Cable size is a key feature; we cannot excuse ourselves from considering why it is critical to consider a cable’s thickness. Now this thickness defines quality. You know that the thicker the cable the sturdier it is and adaptive to withstand stress and abrasion. Coax cable is besides its thickness, has male connector end which is well screwed onto a female connector.

What is a Coaxial Connector?
This coaxial cable we are talking about cannot function without both the male and female connectors. That should show how vital the connectors are. But you could be asking yourself what these connectors are and here is the answer. A coaxial radio frequency connector (RF) is essentially an electrical connector which is constructed with the aim to help at radio frequencies in various megahertz signal range. These RF connectors are technically used with coaxial cables and are designed establish and maintain shielding which is very importance for a coaxial design.

Cable Shield for Leakages
Signals are meant to be preserved and transmitted in a properly safeguarded way. When a signal which should be in a cable passes out, the result at the end may be weak and so to preserve its strength and integrity, a proper shield must be established. Leakages must be minimized at all cost therefore even the connectors must be properly installed. Too much noise leads to an overpowered, weakened and ineffective signal which may not serve its purpose.

However, there will be certain degree of leakage but the leakage should be minimized so as not to cause a major mayhem. A perfect shield would be an ideal conductor with no gaps, no bumps or holes and is connected to a perfect ground. Such shields would be expensive in the long run, heavy, inflexible and impractical. As designers there is a need to comprise on these parameters: cost, flexibility and efficacy of the shielding. The coaxial cables we are talking about here have a perfect touch of design and all these parameters have been keenly considered to ensure that the signals are safe and secure during transmission.

Where are coaxial cables used?
The question of where to use this cable is comprehensively answered here because it is a weighty issue which must be given a fair share of consideration. Coaxial cables are generally used as transmission codes for radio frequency signals, video files and also for data signals. Traditionally, they have been expressly used as feed lines in connecting radio transmitters and receivers with antennas. This cable has also been explicitly used as a television cable, for internet connections and transmission of digital audio signals.

Benefits and advantages of the cables in its applications are as many as to outdo other signal transmission codes. An exceptional design and excellent features that it is endowed with, helps it to work well at high frequencies. You want a cable that can serve you well you’re your application has poor attenuation? This is the choicest of all types. The cable is designed in a way that it eliminates distortion and prevents noise into the signal transmission line

With all the advantages and benefits, the cable apparently lacks no drawback. Its main drawback is its bulkiness. The cable is not designed into small sizes which can consequently be a problem during installation.
