Overview of Best CB Radio Coax Cable
I know all these coax cables are very cool. But it is irrational to buy it all at once. And so I suggest you familiarize with the theory to choose the best coaxial cable ever.
Why Coax Cable for CB Radio?
If you want to save money I have bad news for you. It is impossible to tune up (or something like that) with CB radio without a coaxial cable. So you need to buy it anyway.
The matter is that the coaxial cable serves as a kind of transmission line for radio frequency signals (and receivers with antennas, PC network connections, digital audio, and cable television signal distribution).
There are a huge number of radio transmission lines in the world. And why do you need to buy exactly coaxial cable?
A coaxial cable creates an electromagnetic field that carries a signal between the inner and outer conductors.
For those who are far from physics, I explain: you can lay a coaxial cable next to something metallic (gutters, for example) and it will not reduce the power.
No external interference creates problems for coaxial cable, because it protects the signal from any interference.
So, a coaxial cable has 2 functions (according to which the presence of this thing in your home or car is very important): 1) the cable receives the signal from the antenna and transmits this radio, 2) the cable transmits the signal received from the radio to the antenna.
Best CB Coax Cable Buying Guide
When choosing a coaxial cable, you do not need to blindly rely on the brand or price. It is important to consider many factors because it depends on them how well the whole system will work.
Coax Cable Type
Let’s start with the types so that coaxial cables can be a lot.
This type of coaxial cable is commonly used in radio communications and broadcasting.
The hardline differs from other cable types in that it is built using round tubes (made of copper, gold or silver or all metals at the same time).
If you bought hard line it does not mean that you did not buy poor quality aluminum cable (and it will oxidize and lose efficiency). Therefore, always be sure of the purchase.
These cables are PVC sheathed. And these cables are used for the external chassis. The feature of that is in a thick line (0.5 inches).
And there is also a radiating type (it works without an antenna on ships, in subways and elevators), a three-axis type, a two-axis type (with a twisted pair), a semi-rigid type (with a copper outer sheath) and a conformable type (flexible cable with a copper outer sheath).
But these types of coax cable are rare. Here is what you need:
This type of coaxial cable can be called classic and the most common. RG-6 cable has a sheath of copper steel (and sometimes even of pure copper).
Why is this type of cable the most common? The fact is that the RG-6 coaxial cable is ideal for home (inside and out).
Some models of this cable have a water blocking gel, and therefore people take it in the ground or underground.
This coaxial cable is standard. And so this type of cable is found in all kits. This type of cable has an average shield, an average thickness and a diameter of 0.2 inches.
The RG-8X type is similar to a standard cable, but it is premium. Many people joke that this cable is the same standard, but takes steroids.
This type of coaxial cable has rigid insulation, large diameter and has a stranded center.
This is also a standard, but double coaxial cable. Why would you need such a cable? For example, in the case of a double antenna, because only this type of cable is suitable for such an antenna for truckers for their off-roading cb radio.
Cable length can be from 169 to 220 meters. It all depends on the standards.
For example, an average cable in the United States will have a length of 720 feet or about 220 meters. Be ready it will be 3 feet, 12 feet, and 18 or 20 feet most of the time.
As for international values, the cable length is approximately 186 meters.
RF Power Loss
What does RF power loss depend on? It depends on the loss in the dielectric material that fills the cable. It may also depend on resistive losses that occur in the center conductor and in the external screen.
In both cases, the power loss depends on the frequency – that is, the higher the frequency, the higher the PF power loss.
But PF power loss may be less than the cable diameter is large. In this case, you’d better choose a large cable with a double diameter, it will give half the resistance to the skin effect.
Usually, in the manufacture of cable engineers consider everything. And all you need to pay attention to is the large diameter of the cable.
As a rule, most coaxial cables have the same structure.It has an insulator that is located around the inner conductor and is made of solid plastic or foam.
The inner conductor (needed to transmit an electrical signal) is made of steel copper or stranded copper.The inner conductor is insulated under different amounts of the woven metal braid (as a rule, the number of layers is 4) and the metal tape.
The quality depends on the manufacturer and the materials used. All cables have a comparable quality because they are made from similar materials.
However, you need to avoid aluminum cables inside because aluminum oxidizes and the cable stops working because of this.
If you doubt the quality of the coaxial cable being purchased, read my CB coax cable reviews above.
Coaxial cables can be compatible with home video equipment, radio control systems, metering electronics, computer networks.If you have a twisted pair cable(or cable modem) it is suitable for Internet access.
And coaxial cables are suitable for transmitting cable television signals, radio signals, and signals from a satellite dish.Some coaxial cables are compatible with amplifiers.
Connectors are located at the ends of coaxial cables. What is it for? It is necessary to maintain coaxial form in the connection.
Connectors have a metal shell (made of silver or gold), having a high conductivity and resistant to tarnish. I would opt for connectors with a gold shell because silver can dim and have poor conductivity. It makes cable not efficient.
There are different styles of connectors: barrel style, ring style, and Terminal style.
Barrel style is the most popular connectors, which is usually used for CB radios (since all coaxial cables for CB have a PL-259 connection).
If one end of the cable has a barrel style, then the other end can be any other style – for example, a ring style.
And if this is so in your case, I congratulate you, because ring connectors are useful: 1) a hard cable may not be straight, but go at an angle of 90 degrees, 2) any weather conditions will not affect it, because it is done plastic (no corrosion).
Terminal style connectors (sometimes LUG style) are not as common as the first two styles, because they are less popular. Such connectors can be useful as a sealing connection for side mounting.
But that is not all. There is one more unpopular style – FME unscrewed connectors. You should pay attention to this if you are going to work with small holes (the style of the barrel will be too big in this case).
So, if you work with a small hole, why do you need to do dirty work and solder something? You can use FME style.
Not every coaxial cable has a stranded center. Take any cheap cable and make sure it has a solid central wire carrier. What does it mean?
The tiny part of this cable will break (it will be enough to pinch the door) and the entire cable will be a useless combination of plastic and copper.
But if the coaxial cable has a stranded center (that is, it has many small wires inside), it will not lose the signal from every blow of the wind. And even if some small wire breaks, all the rest will continue to work.
Usually, the RG8X type is equipped with a stranded center. But if you want another type, look in the description of the product whether it has a stranded center or not.
Most coaxial cables pass water (not waterproof) and therefore quickly become useless.
The same goes for protection from heat. Most coaxial cables have a polyethylene sheath that becomes soft (melted) if it is exposed to heat for a long time.
Everything is not so bad. There are types of coaxial cable that are protected from both water and the sun. I spoke about them above – this is an RG-6 cable, which is treated with a water-repellent gel.
The construction affects the physical size of the cable, the frequency characteristics, flexibility and strength, and attenuation. In the end, it affects the price of the cable. The cable construction differs from type to type.
For example, you can meet a cable with a solid internal conductor or with a stranded internal conductor. The second inner conductor will be more flexible.
The inner conductor can be silver plated or made of copper (such as used for cable television).
Any internal conductor has an insulator (as a rule, it is a dielectric material). You can find an insulator made of hard plastic, foam or even solid Teflon (or PTFE). Most often, people opt for a cable with a polyethylene insulator, because it incurs fewer losses in operation.
Maybe you won’t find any isolator in the cable. It means that the manufacturer used air or some gas to isolate the internal conductor.
The insulator is surrounded by copper braid. It makes the cable flexible. You can find a cable with a silver braid or a double-layer screen (that is, it consists of two braids, one of which will be a thin foil and the other braid).
And the last layer of the design is a metal tube. This tube does not allow to sharply cable the cable and make gaps and defects.
The tube is the densest part of the construction because it should not be influenced by the ground, heat, ultraviolet radiation, oxidation and sharp teeth of numerous rodents.
When buying a coaxial cable, you will meet a lot of different brands, each of which will say that it is the best.
Pay attention to such brands as:
All these brands have been on the market for a long time and therefore showed the result of the work.
In addition, these brands are large and produce several types of coaxial cables for different needs, have an affordable price and high-quality products.
I am convinced that the price depends on the quality. However, some brands think too much about their products and inflate the price of low-grade goods.
What to do in this case? Pay attention to the characteristics, and then to the price. And that is only right way to get the best CB radio coax cable.
Installation Coax Cable with Radio and Antenna
Installation of a coaxial cable with radio and antenna is very simple. And you can do it in a few very simple steps.
- If moisture gets into the cable (via connectors), you can forget about the good performance of the cable once and for all.
- Choose the right cable that fits your radio and antenna (and yes, be sure to check the antenna and how much it costs). For CB radio, it is worth making a choice in favor of thick insulated coaxial cable, which has protection from rain and snow, ultraviolet radiation, heat, and sharp teeth of rodents.
- Use connectors made of stainless steel or metal.
Is The Cable Connected To The Antenna Already?
- If the cable has long been connected to the antenna, it will be wise to disconnect the cable for a while and then reconnect it (no need to cut and modify the cable, because CB will not accept such a cable; if the cable does not fit, replace it with a suitable one).
Run the Cable from the Antenna to the CB Radio
- Find a way to lay the cable so that it does not interfere: through the roof of the trunk, the back seat, under the door frame and the window to the dashboard or in some other way that is convenient for you.
- You can do this by adding connectors to connectors of the appropriate size and style.
- Then provide a power source for the radio to start working: either connect to a battery or to aux.
Safety and Maintenance
- Before buying a cable, make sure that the cable connectors are compatible with the connectors on the antenna and the CB (or something else you want to connect the cable to).
- Look for a cable made of copper, polyethylene, and aluminum in certain parts of the structure (what should be copper should not be aluminum).
- Look for high standard coax cables, i.e., those that have successfully passed the high voltage test and have heat shrink connectors.
- Choose the appropriate cable length. If the cable is too long, it will not be powerful enough.
- Choose a cable without twists and turns, then you will find out really high-quality work.
How long the cable will serve to me?
It depends on the original quality of the cable and how carefully you exploit it.
If you bought a poor-quality cable, it will be damaged quickly (or if you bought a cable without a multi-core center, breaking one of the small wires will break the entire cable). However, over time you will have to replace even a high-quality cable too.
I saw “special coaxial cables.” How is this different from standard ones?
Special cables are used for lasers, various measuring devices, rent, camera and video, and so on. As a rule, special cables have fewer losses and flexible braids. In an ordinary radio tuning, you cannot use it. Maybe coaxial cable not working for stubby antenna.
I placed the coax cable, but this is too noticeable. How to fix it?
One of the disadvantages of the coaxial cable is that it is too big and takes up space. If the cable bothers you in the house, you can hide it behind the TV or in the plinth.
I’ll tell you a little secret – you can hide the cable inside the wall. The cable case is strong enough to be hammered into the wall.
Does CB coax length matter?
Yes, the coax length in CB radio matters as it will affect the performance of the antenna. For instance, the longer the cable, face more loss in signal. The other factor is the thickness of the cable. If it’s too thin, the loss will be more. So, yes, coax length matters a lot.
Can I use 75-ohm coax for CB?
Yes, you can use it. But there will be an impedance mismatch that might not offer the great performance that you wish to get.
Is rg59 better than rg6?
It solely depends on the application. For example, while dealing with a higher frequency like Television and the internet, rg6 is the obvious choice as there is less loss of signal. But using for a low-level frequency, you might want to go with rg59.
How can I improve my coaxial cable signal?
There are a couple of ways you can improve the coax cable signal. But the usual ones are changing the long cable with a short one or just introduce a house amp that will boost the signal through it.
Are coaxial cables all the same?
No, they aren’t all the same as there are different sizes and materials used to make them. And each of the different kinds of cables has its pros and cons depending on their size and materials used to make them.
How to determine the length of coax cable needed for CB?
Many tests show that an 18-foot cable is the best as it provides the optimal performance.
Can you use a TV coax for CB?
Yes, you can use it as modern devices can handle impedance quite easily today. Though the rig requires a 50ohm cable, the cable 75-ohm coax won’t cause any problem for the CB.
Can you splice a CB coax cable?
The answer is no, you can’t splice it. The reason behind this is because it is a single-center conductor with a continuous shield surrounding it.
What affects your CB COAX cable?
Many things can affect the coax cable, from its length to its thickness to the band frequency, all have an impact on the performance. Not only that, even rolling up the cable in a coil can create a radio frequency choke that hurts the performance big time.
How do I know if my coax cable is bad?
You can use it with a multimeter to check whether there is too much noise in the cable to know whether it’s good or bad.
How should I store coax cables?
Don’t roll it. Make sure to have the coax cable lined up in a manner without a bend to assure that the performance doesn’t deteriorate in the cable.
So now you know all about coaxial cables.
I hope you will take my advice when buying. It will allow you to make the right choice, buy the best CB coax cable and forget about this problem for a long time. Good luck!
