Strip Braided Coaxial Cable? 97 Most Correct Answers

A coaxial cable is an electrical cable with a copper conductor and an insulating shield around it and a braided metal braid that prevents signal interference and crosstalk. Coaxial cable is also known as coax.

The core copper conductor is used to transmit signals, and the insulator is used to insulate the copper conductor, and the insulator is surrounded by a braided metal conductor, which helps prevent electrical signal interference and crosstalk. This entire structure is in turn covered with a protective layer of plastic to give the cable extra security.

Structure of the coaxial cable

Copper Conductor: A central conductor made of copper. The conductor is the point where data is transmitted.

Insulator: Plastic dielectric insulation around the copper conductor. it is used to maintain the spacing between the inner conductor and the shield.

Braided Braid: A braided copper braid helps shield against EMI. The braid provides a barrier to EMI moving in and out of the coaxial cable.

Protective Plastic Layer: An outer polymer layer that has a plastic coating. It is used to protect inner layers from damage.

Types of coaxial cables

Hardline Coaxial Cable: The inner conductor of hardline coaxial cable is made of copper, silver and has a larger diameter compared to other coaxial cables. Flexible coaxial cable: The flexible coaxial cables are very flexible and the inner conductor is surrounded by a flexible polymer. Semi-rigid coaxial cable: Semi-rigid coaxial cable uses a solid copper jacket with a polytetrafluoroethylene dielectric. Malleable Coaxial Cable: It is an alternative to semi-rigid cable that uses a flexible metal jacket instead of a rigid copper outer jacket. Twinaxial Cable: It has two central conductors in the core and a single outer core and dielectric. These cables are best suited for low frequency digital and video transmission. Triaxial cable: It is also known as a triax. It is very similar to coaxial cable, but with the addition of a copper braid, the braid acts as a shield and protects against noise. Triaxial cables offer more bandwidth. Rigid Coaxial Cable: Rigid coaxial cable consists of two copper tubes supported at the cable ends and at fixed intervals along the length of the cable with PTFE supports or disc insulators. The rigid coaxial cable cannot be bent. It is mainly used in TV and FM broadcasting systems.

Applications of coaxial cable

The coaxial cables are used in Ethernet LANs and also in MANs

Television: Coaxial cables used for television are 75 ohm and RG-6 coaxial cables. Internet: Coaxial cables are also used to transmit Internet signals, RG-6 cables are used for this. CCTV: The coaxial cables are also used in CCTV systems and both RG-59 and RG-6 cables can be used. Video: The coaxial cables are also used in video transmission, the RG-6 is used for better digital signals and the RG-59 is used for lossless transmission of video signals. HDTV: HDTV uses RG-11 because it offers more space for signals to be transmitted.

advantages

Coaxial cables support high bandwidth. It is easy to install coaxial cable. Coaxial cables have better cut resistance, so they are more reliable and durable. Less affected by noise, crosstalk or electromagnetic interference. Coaxial cables support multiple channels

Disadvantages

Coaxial cables are expensive. The coaxial cable must be grounded to avoid crosstalk. Because a coaxial cable has multiple layers, it is very bulky. There is a possibility that the coaxial cable will break and a “T-piece” will be attached by hackers, jeopardizing the security of the data.

How many electronic cables do you have lying around right now? Probably a lot! It is estimated that globally this year alone we will throw away 40 million tons of e-waste, including the wires and cables that we use to charge our phones, power our computers and run entertainment centers. We’ve teamed up with Eland Cables to explain why it’s so important to recycle old wires and cables instead of just throwing them away.

Too much e-waste

E-waste is the fastest growing sector of the waste stream. In fact, 85% of our e-waste ends up in landfills and incinerators, and that’s not good for the planet. Electronics contain heavy metals and plastics from various compounds that, over time, make their way into the air, water and soil, potentially contaminating the water we use to drink, wash and clean.

Communities are responding as the problem worsens. Throwing away e-waste, even if it is “just” electrical wires and cables, is illegal in the UK, much of Europe and many jurisdictions in the United States.

Pollution aside, there is another reason why there is no point in disposing of e-waste such as wires and cables. They contain important and difficult-to-obtain metals such as copper. Mining the copper needed to make cables is quite devastating to the environment in which the mines occur. Deep, open copper mines in places like Butte, Montana are notorious for how ugly, polluting, and destructive they are.

Although other rare metals are also used to make wire and cable, copper is ultimately the most common electrical and electronic conductor on earth. In recent years copper has become scarce which has resulted in higher prices which in turn increases our cost of purchasing electronics as well as more copper mines.

Recycling old wires and cables is one way to reclaim copper without all of this environmental destruction.

How to recycle old wires and cables in your area

Recycle

Copper sells for just over $3 a pound. Any metal recycling yard will be happy to take your cored copper wires, the more the better. BestBuy, Staples and other electronics stores also help with electronics recycling.

In fact, in addition to wires and cables, they accept most of your small electronics. You can also sell your used electronics here.

reuse

With the exception of some Apple products, most of your home entertainment cords and cables can be used with other devices. For example, the cable I use to charge my Kindle Fire can also charge my Samsung Galaxy phone.

New electronics come with their own power cords, but not necessarily HDMI or coax. It’s a good idea to keep a set of backup cables to use with your devices. Whatever you can’t reuse yourself, ask your friends and family if they can.

Donate

Many schools and nonprofits are happy to accept electronics donations, even if you just have an occasional power cord or an old Ethernet cable that wasn’t quite long enough.

STEM – Science, Technology, Engineering, and Mathematics – programs across the country are always looking for ways to save money to get the items they need for their programs. Just google STEM or National Center for Electronics Recycling to find out what’s available in your area.

Finally, you can always visit Earth911 to learn more about where you can recycle electronics in your neighborhood.

Coaxial cable is a form of signal transmission cable used to carry electrical signals between devices, systems, or components. While traditional electrical cables consist of one or more wires through which an electric current flows (a flow of electrons), coaxial cables are used to transmit radio frequency (RF) signals in the form of a transverse electromagnetic wave. Coaxial cable design consists of an inner conductor surrounded by a dielectric layer, which is then encased in a cylindrical sandwich containing additional layers of shielding as well as an outer protective jacket to prevent damage to signal-carrying components during installation or by environmental stresses . Commonly used as transmission lines, coaxial cable can carry high-frequency signals with low losses.

Common types of coaxial cable include:

Hardline coaxial cable

Flexible coaxial cable

Semi-rigid coaxial cable

Malleable coaxial cable

Rigid coaxial cable

Twin axial cable

triaxial cable

The terms coaxial cable and coaxial cable assemblies are often used interchangeably, however some references distinguish the two by defining the assembly to represent the cable material terminated and readily available in standardized lengths. In this context, coaxial cable would represent bulk cable sold in spools or spools, say 100 or 500 feet in length, to which cable connectors are attached once the final cable length has been determined.

Types of coaxial cables

The following sections provide a brief description of each coaxial cable type.

Hardline coaxial cable

Hardline coaxial cable uses a center conductor composed of materials such as copper, silver, aluminum, or steel, and this type of cable is typically larger in diameter than other types of coaxial cable. These types of cables can be used in high strength signal transmission. Some forms of fixed line use pressurized nitrogen as an inhibitor to moisture ingress and to prevent arcing.

Flexible coaxial cable

As the name suggests, a flexible coaxial cable can move and bend as needed to fit the configuration and geometry of the application. A typical flexible coaxial cable design uses a metallic inner conductor surrounded by a flexible polymer that acts as a dielectric, with an outer jacket for protection from the environment. When there is a need to increase flexibility, the metal core conductor can be switched to a solid wire stranded design, and a polyethylene (PE) dielectric foam can replace the stiffer dielectric material.

Flexible coaxial cable is the most common type of coaxial cable and is well known to everyone who has used it to connect home video equipment and televisions.

Semi-rigid coaxial cable

Semi-rigid coaxial cables use a solid copper jacket with a PTFE dielectric. The copper jacket generally offers superior shielding effectiveness and the dielectric properties offer improved high frequency performance. Because of its construction, this type of coaxial cable is not intended to be reshaped or bent after the initial forming process has taken place.

Malleable coaxial cable

An alternative to semi-rigid coaxial cable is malleable coaxial cable, also known as conformable coaxial cable. Instead of a rigid copper outer jacket, a flexible metal jacket is used that can be reshaped and formed by hand to meet the desired cable configuration, which requires special tools. Malleable coaxial cable is sometimes used to create the design for cable placement in prototype applications and once stabilized the design is converted to use the semi-rigid coaxial cable.

Rigid coaxial cable

Rigid coaxial cable, sometimes called rigid conduit, consists of two concentrically mounted copper tubes supported at fixed intervals along the length of the cable with PTFE supports or disc insulators. Although referred to as rigid coaxial cable, the term rigid coaxial transmission line is perhaps a more appropriate moniker since cable has traditionally been thought of as being flexible or bendable. Rigid transmission lines are manufactured and sold in flanged straight sections of a specified fixed length. As a result, a set of standard connectors or couplings, such as B. 45 or 90 degree bends are available to connect the sections of the transmission line together as required. Special struts and springs are also used to allow for the differential expansion and contraction of the inner and outer copper tubing used in the transmission line.

Twinaxial cable

Twinaxial cable (also known as twinax or twinax) has two central conductors contained within the core with a single outer core and dielectric instead of the traditional single conductor design of most coaxial cable types. Some benefits of Twin-Axial cables include reduced cable losses, greater protection from ground loops and capacitive fields, and a reduction in low-frequency magnetic noise. These cables are best suited for use in low frequency digital and video applications.

triaxial cable

Triaxial cables, also called triax, are coaxial cables to which an additional copper braid has been added. This braid acts as a shield and is grounded, directing ground loop currents or capacitive field noise away from the conductive elements of the inner core. Triaxial cable offers increased bandwidth and interference rejection, offers an improvement in signal-to-noise ratio over standard coaxial cable, and reduces cable loss and cable stress.

Other types of coaxial cable

Some other specialized types of coaxial cable are:

Custom coaxial cable design and manufacturing services are also available for special requirements.

How the coaxial cable is specified

Common specifications for coaxial cable include:

Cable type or RG type (which stands for Radio Guide) is now largely an obsolete reference because the underlying standard that defines these terms is no longer an active document. RG-6 is a very common type used in home video applications.

The inner core conductor material can be bare copper, silver plated copper, tin plated copper or aluminium/copper to name a few choices.

The impedance of the cable. The most common values ​​for impedance are 50, 52, 75 or 93 ohms.

The jacket material that serves as the outer protective layer of the cable.

Key cable dimensions including length, outside diameter and wire size.

The desired connector configuration, which includes both the desired gender and the specific connector style such as BNC, SMA, SMB, or N-Type.

The minimum bend radius

The attenuation, measured in dB per unit length of cable

The nominal temperature for the cable

A while back I spoke to a loyal customer who asked me if it was possible to get electrocuted from a coaxial cable. Let’s say this question raised a lot of red flags. I’ll put it in big letters:

You should never get a big shock from a coax cable. If you are electrocuted by a coax cable, contact an electrician NOW.

Serious.

A coaxial cable can carry electricity. If the cable’s center conductor is solid copper, it supports it quite well. The solid copper core RG6 is constantly used to power amplified antennas and satellite dishes. However, it’s not capable of carrying the amount of power you would get from an outlet. While it would work for a short time, carrying 110 volts and up to 10 amps would generate a lot of heat that would cause the cable to fail. It’s just not designed for that.

If you get a real shock from touching a coaxial cable, you should probably call an electrician before you even finish reading this article. The sooner the better.

How much current can safely flow through a coaxial cable?

DIRECTV satellite units use a power inserter that routinely sends 29 volts at 1.4 amps down a wire. This is enough to cause tingling when you touch the center conductor, but you should never feel a shock just by touching the outer connector.

I’m sure there are other devices that send more power over a coaxial cable, but I’m not familiar with them. So I can say that you should never run more than 29V / 1.4A (~40 watts) through a coaxial cable. You don’t have to. Most antenna boosters only put about 5 volts through a wire.

Why can’t you route more through a coaxial cable?

It depends on the thickness of the copper center conductor and also the dielectric foam that is in the middle of the cable. The foam is designed to allow the signal to “stretch” into this space, giving it a better path. While the white dielectric foam is fairly safe, it is not rated for extremely high heat applications. If you ran a lot of current through a wire that wasn’t designed for it, you would generate a lot of waste heat. This could cause the foam to fail and with it the entire cable.

The other problem is the braid around the cable. When used for signals, a coaxial cable only carries signals on the center conductor. The outer braid is used for shielding. When carrying current, the outer braid acts as a neutral branch. It’s much more delicate than the center conductor and could fail spectacularly as well.

Seriously, electricity is no joke.

If you’re getting more than a tiny shock from your cables, something is wrong. It could be something as simple as a bad ground, but it could also be a sign that the cable isn’t being used as intended. A defective cable could start a fire and destroy your entire house. This is a very serious matter and please, please have things looked at by a professional if you are at all concerned.

You can make a surprisingly good digital TV antenna out of a piece of unused coaxial cable. This homemade antenna, which you can make in 15 minutes, may not pull in distant signals, but it will pull in dozens of HDTV channels in a subway area.

You can build a basic TV antenna by stripping the last 6 inches of insulation from a standard coax TV cable, folding back the shield, and leaving 6 inches of bare copper wire. Where I live, 10 miles from the St. Louis city limits, this simple antenna picks up 40 channels. If you live outside of a big city, you’d be better off with a Gray Hoverman theme.

what you will need

This DTV antenna requires very few tools or materials. You need the following:

Standard coax TV cable, at least 30 cm long

diagonal cutter

needle nose pliers (optional)

utility knife

Electrical tape or 3/8 inch heat shrink tubing

rubber gloves or work gloves

Hair dryer when using heat shrink tubing

And it literally is. It is best if the knife includes a new or relatively new blade as you will be carving some plastic. I use heat shrink tubing because it’s easier and the results look better, but you can use electrical tape.

Surprisingly, I didn’t have any unused coax cables lying around, but I did find a few at thrift stores. I paid €1 for one and €2 for the other. If a cable is two feet long, you can cut it in half and make two antennas out of it.

Cut the coaxial cable

If you cut cable, you could literally cut the cable from your cable or satellite service and turn it into an antenna.

I don’t know the minimum length of cable to use, but I can tell you the ones I made are around 1.5 feet and work fine. If you want a short, unobtrusive antenna, feel free to experiment. Most coax cable you’re likely to find is a good 3 feet long if not longer, so you can probably make two antennas out of one cable.

Cut the cable in half with your wire cutters, or if your cable is very short, just snip off the end. Coax cables are tough, so it may take 3-4 cuts with your wire cutters to get through. Leave the plug on one end as this will plug or screw into the TV’s antenna connector.

stripping and shielding

Measure six inches from the end, then use your utility knife to trim the insulation. You’ll have to cut all the way, so expect it to take at least four passes. And remember what you learned in Boy Scouts: cut away from you, not towards yourself. I find it easiest to cut the cord, then tug on it a little to make sure I can get through the insulation, then that Rotate cable 90 degrees and repeat.

Once you’ve cut all the way through the insulation, you should be able to pull the end off in one piece. Throw this piece away; You won’t use it for anything.

Underneath you’ll see a lot of braided insulation. You might want to put the gloves on at this point. Some cables are made with a really sticky adhesive. For others it is mild. If the insulation feels very sticky, you should put on the gloves.

At this point you can pull back the braided shield. Just drag it back out of the way for now; We’ll make it look neat later. It will fray a little at the edge as you pull it back, but that’s okay.

Stripping the plastic core

Now the tricky part: the metalized plastic core. There’s no really good way to do this. Basically you need to hold the cable over a trash can and cut away the plastic core with your utility knife. If you angle it just right, you might be able to cut a long slice almost the full 15cm length. Other times, you’re lucky enough to get a 1 inch chunk. Just work very carefully and cut away from you and carve down to the copper. If the surface facing you is facing bare copper, rotate the cable approximately 45 degrees and repeat the process. It takes me about four passes to get bare copper all the way down.

Insulating the shield to terminate the coaxial cable TV antenna

We are nearly finished. Cut a piece of 3/8 inch heat shrink tubing long enough to cover the braided shield with some extra on each side. I find about 7 inches does the job. Pull the shield snugly over the insulation, then slide the tubing over the copper end and onto the shield, leaving about a quarter inch overlap on the copper side. Shrink the tube with a hair dryer on high heat.

If you don’t have heat shrink tubing, wrap the braid with electrical tape. Pull the braid taut, then wrap it tightly with electrical tape, starting at the end closest to the connector and spiraling up to the copper.

To be on the safe side, I suggest you glue a bead to the end of the copper wire so it doesn’t poke anyone.

Use your coaxial cable TV antenna

Using your coaxial cable TV antenna is easy, just like any commercially made antenna. Screw it into your TV’s antenna input, then use your TV remote control to access your TV’s menu. Set it to Antenna or Over-the-Air, and then perform a channel search. In my case, depending on where I am in the house, I can receive between 38 and 51 channels. It works about as well as most $6 antennas but better than some. I made one to replace a $6 antenna that was performing poorly and liked it so much I made two more.

I get more consistent results with a Gray Hoverman antenna because I can get 51 channels anywhere in the house with one. But this antenna is easier and cheaper to manufacture and takes up less space. Between a halfway decent antenna and judicious use of Roku boxes, I don’t need a wire.
