The axial cables were a cornerstone in the transfer of data for decades, which made everything from the cable TV to the high -speed internet. However, although it is widely used, axial technology is surrounded by misconceptions that often lead to confusion.
In this blog, we will deal with the most common myths and concepts about the axial cables, explain the facts, and help you make enlightened decisions for your projects.
Axial cable structure
Let’s jump directly!
The wrong belief: A pivotal cable does not need to ground.
Indeed, according to the national electrical symbol (NEC), it should be established. And if it is veiled to go to the antenna mast, the mast should also be a sign. If your cable service is used Coax to enter your home, there is a grounding block near the entrance to the cable associated with the ground system of the structure, usually at the ground rod. So in most homes, the central network of cables is already based.
You may install a pivotal cable for a different purpose, such as installing a plate of satellite. You will need to make sure that the cable may be based, not only to meet the code, but to work properly as well. To establish the cable, install a grounding block for F. Use the #14awg wire to connect the mass to the ground system. If you have a mast needing the ground as well, use the #10awg wire to the ground system to make the bond to the air mast.

Cable fasteners are usually associated with the pivot cable entrance to the Earth’s rod, because in most homes, they are likely to be close to each other. Even if not, we recommend not to drive a new ground rod. Any additional ground bars should be combined into the current ground electrode system, and there are rules to do so. If this seems to be a problem, it will be good to have an electrician on board.

The wrong belief: A pivotal cable cannot work in today’s network speeds.
The performance of the cable depends on the attenuation (the signal loss in DB/100ft), the external electronic effects such as electromagnetic interference, fixed accumulation, and restrictions on technology that provides signal. For most users at this time, COAX internet service is limited to about 1 GB per second using technologies such as Docsis and MoCA. Subscribers to the services provided via optical fibers are also operated at a speed of 1 GB per second for most users. Therefore, you may say that COAX works well at the speed of the network today. But some fiber providers started providing services at 2.5, 5 and 10 GB per second. We’ll see if COAX technologies can keep up with it.
Poor belief: The four -protection cable provides faster performance over longer distances than a double shield.
Consider a quadruple cable only after looking at the electronic environment at the installation site. If there is a source of fixed charging or electromagnetic interference, you should think about the Quartet cable. The only difference between the double shield and the quadruple shield is the amount of shielding. If there is nothing to shield it, there is no difference in performance. Without a source close to electromagnetic or fixed electromagnetment, there is nothing that can be acquired with a quarter cable.
Also, remember that cables with a quad, more heavier, more intense and more solid, are often more difficult to finish. I think COX SquIELD COAX is great, but only when I need it.
The wrong belief: The more hardy braid, the more effective the shielding.
It may seem clear that if you use more minerals in the shield, shielding is more effective. However, the host shield is just one part of the shield. The shield consists of the brake item, but it is also a foil component. The braids, chips, and even the interconnection method are part of an improved design to provide the most effective shield in the most common operating frequencies.
A heavier braid will make the entire cable heavier. Not only that, it will make the cable more solid and more difficult to finish. Even if it seems that the braid leaves some gaps on the surface of the protection, you can be confident that the shield is designed for optimal performance.
The wrong belief: the axial cable is a commodity element that will perform the same, regardless of the price.
Not all axial cables are designed and build the same thing. Also, the quality of materials and manufacturing varies between different manufacturers. Aluminum is widely used for each of the components of the axial axis and axial chips, but be careful of aluminum in the central conductor.
For many applications, CACS (CCS) steel is suitable for the central center connector, however, all our axial cables are made of a steel copper center connector, which increases conductivity and reduces signal loss due to attenuation. It may be a little more expensive, but we believe that low signal loss is worth it.
The wrong belief: the optical fibers are always faster than persuasion.
When it comes to Coaxial Vs Fiber Optic cables, it is widely recognized that optical fibers are able to achieve faster speeds in most circumstances.
But let’s focus on the word “always”. This is where things are difficult. Both axial cable and optical fibers theoretically transmit data. The main difference in attenuation lies: There is more signal loss (attenuation) with copper in the axial cables due to electrical resistance. This makes optical fibers in general faster in longer distances and higher data loads.
However, there are specialized scenarios where COAX may outperform the optical fibers over very short distances. Although I cannot think about a specific example of my head, I can imagine that it is theory.
Here is a fun hypothetical: If your optical fiber cable is One spot of dust on its final faceIt can hinder the performance enough that persuasion may actually be faster at that moment. In addition, COAX does not require a lot of maintenance – no need to carry a Dust!
What about this? If your fibers are One spot of dust on its final faceThen it will be faster. I do not have to carry anything Dust.
Coachery: Coax Series-6 (RG-6) is an updated alternative to Series-59 (RG-59) Coax.
Both the Series Cable -6 and Series-59 are still in use. The Series-59 cable is used for low frequency applications such as the closed radio and television antennas. The Series-6 cable is more suitable for high-frequency applications such as broadcasting of broad domain data and high-resolution TV. Since high frequency applications are more popular these days, it may seem that the Series-59 cable has been replaced by Series-6, but this is not the case.
Series Cable -6 and Series -59 chain cable, both of which were prepared for the end. The insomnia observed the central insomnia in the series cable-59, and the diameters smaller than the electric insulation and the jacket.
The choice of the cable is determined by the electronic equipment requirements that are connected to it. Series-59 cable has a 50ω resistance value. Series Cable -6 has 75ω resistance. The appropriate cable should be chosen to ensure that the disabilities match all over the transmission channel. Both Series Cable and Series-6 Coxial still have their right applications.

Poor belief: The axial cable can transmit a signal from the ethernet box.
Once on the day of low -precision analog signals, it was possible to effectively operate a hundreds of hundreds and perhaps up to a thousand feet. This may still be true for certain types of signals, but not for broad domain data signals. For any specific axial cable, the higher the signal of the signal, the shorter the distance so that the loss of the sign is very large so that the signal cannot be used. Broad domain systems and digital satellites work at very high frequencies. For these signals, COAX from Series-6 (RG-6) can lead to a distance of 46 meters (150 feet).
The Ethernet (Copper Twised -Pair) is developed specifically to transfer digital data signals via ETHERNET. It is designed to perform a distance of up to 100 meters (328 feet). Series -11 (RG -11) can be apparently from the many ethnic cable Multiple or users.How long can I run a pivotal cable?“
The wrong belief: ancient cable.
A pivotal cable is still alive and healthy! It is used to transmit cable TV, closed circuit television, audio and visual systems, and satellite TV systems. When the Ethernet Protocol was first developed, use a pivotal cable for network connections. It can still be used for today, but the speed will be slow compared to the twisted copper ethernet cable.

So what about modern axial cable applications? Can you still use a pivotal cable for the Internet? New technologies such as Docsis and MCA allow the use of current central cable installation operations for high -range applications. Docsis is a technique that allows the transmission of broadband signals to each of the cable and the Internet to distribute to buildings via the axial cable. MCA is a technology that allows the axial cables already in buildings to be used to transfer broadband signals. However, the use of MoCA requires investing in electronic devices to transform the signal between protocols. Also, MoCA is currently limited at 1 GB speeds per second. If you want to learn more about MOCA, its benefits and restrictions, check the entry of our blog, “MoCA opposite ethernet“
If you want faster mesh speed speeds, the axial cable inside the structure may need to already be replaced. The new DOCSIS 4.0 technology with 10 GB Internet service is provided by powerful and hybrid networks. However, although the Docsis modem and routers are characterized by a ppotist input, there is no ruling on pivotal output. All output ports are RJ45 Jacks for Ethernet cable. The good news is, as long as your inner pivot cable does not interfere in its place, you can use the old cable to pull the new brand CAT6A Twisted-Pair Eternet CableWhich will support speeds of up to 10 GB per second.
conclusion
So there are you. Nine common wrong concepts were often exposed about the axial cable.
The axial cable is still common and is expected to remain so. Coaxial distribution networks that provide internet service will soon be operating at a speed of up to 10 GB per second with the start of Docsis 4.0. However, local region networks may benefit from a cable infrastructure update.
The axial cable is still a vital and versatile part of modern communication systems. By understanding the facts, you can make enlightened decisions and avoid common pitfalls. We hope some of these decisions will become easier.
