What to Look for When Buying a CB Coax Cable

Now you are all aware of the importance of having a suitable CB coaxial cable. You can really tell the differences between using a high-quality radio cable and using a mediocre one. The antenna cable is one of those things that you should definitely invest in.

But of course, that doesn’t mean you should spend a huge amount of money to buy the most expensive and complicated cable. What you need is a product that is “tailored” for you – the one that fits your preferences and needs.

We are here to help you find out the perfect fit among a myriad of products on the market. There are a lot of things that need to be considered when buying an antenna cable, but here is a list of things that should be the priorities in my opinion.

Length – The first advice that I could give you is to pay careful attention to the CB coax cable length. It is a simple thing to do but many people often ignore it.

Anyone would understand the frustration of buying a cable that is too short to connect two devices. Even if you buy a long cable to be 100% certain that it would fit, this only increases the chance of tangled wire.

I suggest that you should have in mind a size that you want your cable to be before making any purchase. Then you proceed to buy the exact length that you want. Many products offer different length options for you to choose from, from short cables to much longer ones.

A little reminder is that sometimes there might be slight variations between the product information and the real cable. Make sure that you check it carefully, as well as consult other customers’ reviews.

Material – The quality of the cable depends mostly on the material it is made from, or specifically what the core wire is made of. Different kinds of metals can be used to make the wire, and each material has its own strengths and weaknesses.

Therefore, you should do a little research before buying, to see what metals would fit your needs best. For example, aluminum is lightweight and cheap, but it oxidizes quickly. As for the outer jacket, you should choose those made from high-quality plastic to ensure safety while using.

Connectors – The CB coax cable ends are critical since they are directly plugged into your devices. Good connectors that fit the jack nicely and tightly will keep the connection stable. Also, you need to pay attention to the materials that connectors are made of. Some metals might tarnish after some time, so you should choose something with good weatherproof quality.

There are many types of connectors, normally divided by shapes. The most common types include ring style, barrel style, terminal style, and so on. You should check which types of connectors would fit the ports on your devices.

Price – You should not forget to check the price. There are many coaxial cables at different price ranges. Shopping around would allow you to compare the prices and choose just one product that fits you the most.

Don’t fall into the consumerism trap by going right away at the most expensive product. The best CB coaxial cable can not be decided by prices, it is what ticks most of your boxes and can give you a satisfying experience.

Frequently Asked Questions

What are the most trusted CB coax cable brands?

You will see that there are a lot of brands producing CB coaxial cables now on the market, and each person would have their own idea of the best brand. Some brands that I’m impressed with include Astatic, Wilson, TruckSpec, CablesOnline, and so on.

Can you use a TV coax for CB?

You can plug the TV coax cable on your radio but I don’t suggest you do so. A 75-Ohm TV cable won’t be compatible with the antenna feed line that is designed with the impedance of 50 Ohm.

If you insist on connecting the TV cord to the radio, the device might likely break down. Please refrain from doing so.

How long should my CB coax be?

It really depends on your purposes and the distance between your radio and the antenna. Buying a cable that is long enough to cover that distance comfortably, but avoid buying something too long. You don’t want your cord to be entangled into a mess.

How to shorten CB coax cable?

Use a cable cutter to cut your coaxial cable to the desired length and then crimp the wire together. A typical cable will have three layers, and when you cut it open, remember to connect the right wire together.

However, I don’t recommend any form of tampering with the cable. If anything happens, replace the old cable with a new one.

How to put an end on a CB coax cable?

First of all, use the cable cutter to strip off about 1.5 inches of the outer jacket. Trim down the braided strand shielding and fold it back on the outer layer. Continue the same step with the insulation. Put the wire through the connector and screw it tight.

This is our recommended steps to install a connector. For visual aids and clearer instructions, watch tutorial videos from experts so that you can successfully install it.

How to run CB coax cable?

It is actually simple to run a coaxial cable to your CB radio. First of all, you need to find an appropriate place to lay your cable. It could be under the door frame, along the foot of the wall, or through the window – whichever way that looks neat and works best for you.

Once you have done with the first step, just plug the connectors into the right place. Check carefully to see if it fits to prevent it from coming off later. There you go, you have successfully installed the cable to your radio system.

Can you splice a CB coax cable?

In theory, you can splice a coaxial cord using some splice connectors. Some websites might have some of these products on sale. However, I do not recommend doing so, since those connectors are not reliable. The best thing you could do is to install a brand new cable.

Where to buy?

When it comes to electrical devices, I always want to come directly to the stores to have first-hand experience with the products. You can easily find most of the products mentioned above at any local stores, and even in Walmart.

If you can not go out to buy the cable, you can always turn to the online shopping sites. Of course, it is of great convenience, but you should be extra careful and double-check everything before making a purchase. Some reliable websites you can check out is Amazon, HomeDepot, and so on.

What is the warranty?

It depends on each brand. Each brand has its own warranty policy and customer service. Before making a purchase, you should check it out to see what works best for you. Normally, the warranty might last for 8 to 12 months, and you can even get a full refund during the first few months if you discover any faults during the manufacturing process.

How to care and clean?

It is not difficult to take care of your antenna cable. You should keep the cable in a dry place and avoid direct sunlight. If the cable gathers dust after a long period, use a clean cloth to gently wipe it off. If you don’t use it, roll the cable into a nice coil then keep it in the drawer or in your toolbox.
