What to Look for When Buying a Good CB Antenna Cable?

Despite its not-so-cool an appearance, a coax cable plays a vital part when establishing a radio connection. Since it’s imperative for every transmission and reception to travel throughout the length of coax cables, you must pay close attention to several essential factors when buying one.

Let’s discuss those essential aspects in detail, so you don’t have to curse yourself anytime soon for buying a cheap cable.

Know the Types of Connections

First off, you must learn about the different types of connections to figure out the right one that you’ll need. Despite all of them mostly sharing a similar construction, the type determines its suitability for various purposes.

Barrel Style (PL-259)

In the world of coax cables, it has been known to be the most popular connection type. These connections come with a screw-on-barrel appearance.

All the coax cables are most likely to have this sort of connection. Whenever you take a cable on your hand, you’ll find it on one of its ends at the minimum since it’s considered as the standard connection type for plugging into the CB radios.

Ring Style

The ring-style ends are popular among many people, particularly for two of its most generous advantages.

Firstly, it allows the coaxial cable to get off the mount vertically because of its low profile. It becomes beneficial mostly during tight mounting circumstances.

Secondly, these exclusively plastic-made cables withstand moisture and rough weather better than the barrel-style ones, which are made of metal. Meaning, they hardly rust or get stuck.

Terminal/Lug Style

This rare kind of connection is used in only a handful of unique situations. It uses a small o-connection to connect into the sleek and clean mount applications. You may find it on several ball mounts or side mounts that utilize both the inner and outer surface.

FME Screw-Off End

It’s likely that you’ll often come across tiny firewall holes or openings while routing CB cables. And you may find it too awful to fit a barrel connector, that is bigger in size compared to the smaller slot. It will leave you with the option to re-solder the PL-259 connection, which can be tedious.

FME connections, on the other hand, are excellent substitutions in this regard as they allow removing the barrel for a more comfortable routing of those narrow coax. And once you have successfully routed the cable, you can quickly screw it back together without having to mess with soldering jobs.

Quality Grade Variants of CB Coax

Let’s take a look at the different quality grades of coaxial cables and how they fare.

RG-58 (Standard)

It’s the most common coax grade found in most mounts and kits. The exterior thickness is average, along with moderate shielding capabilities. Its cable bore measures nearly 0.20 inches.

RG-8X (Premium)

RG-8X works pretty much like the standard ones. When pinched or bent, this coax is unlikely to snap. It’s because of its stranded center, unlike that of cheaper coax with solid ones.

Its diameter measures close to 0.25 inches, which is thicker than the norm while it also boasts sturdier insulation.

You’ll be wise to go for RG-8X coax if you want a heavy-duty solution to withstand potential abusive impacts.

RG-59 (Dual Antenna)

For devices running on a dual antenna, there’s no other option than the RG-59 coax. No dual antenna setup works with any other coax variations.

A few may go and try regular cables, attempting to pull out T-connectors for every installation. But in reality, with all the things wired up, the dual antenna setup will simply refuse to work.

A Few Other Essential Quality Factors

Material

As we’ve said earlier, coaxial cables mostly come with likewise constructions with similar materials. In general, they are made of aluminum, copper, and polyethylene.

The quality depends on the standard of such elements rather than their attributes. However, you’ll be better off to forgo aluminum coax as it’s more inclined to get oxidized.

Stranded Center

Cheaper coaxial cables mostly work on carrier wires having a solid center. But since it’s only a single piece, the cable becomes useless and can’t carry signals once it splinters or breaks.

In contrast, stranded centers having so many short carrier wires, hardly miss a signal. And even when you break one of the strands, there’ll be countless backup options to make sure of your signals to get through.

All the RG-8X come with stranded cores. But to assure yourself of whether an RG-58 or an RG-59 has such a core, you need to check their product descriptions.

Hand-Soldered or Machine-Soldered

Hand-soldered ends are likelier to be of better quality compared to machine-soldered ones, for they come with more deftly finishes. Meaning, they are less prone to breakages or come out faulty.

Frequently Asked Questions

1. What should be the length of an ideal CB coax?

It depends on your needs. Most of the companies chose 18-feet as their standard size, but it can often fall short if you’re working on low-signal conditions where it’s necessary to take out your device as far as possible.

2. What if my coax isn’t long enough to allow me taking it far away?

There are several extension cables available in the market that can extend the length of your existing cable. However, you must check its compatibility before making a purchase.

3. Is SWR affected by cable length?

Mostly not. But if you add external coax, you may encounter lower SWRs.

4. How durable are these cables?

The cables we’ve reviewed above are more durable than most other models in the market. Except for the RoadPro, all the rest are likely to last for at least two years. Additionally, the Cable Experts cable may last up to five years for its exceptionally sturdy build.

5. Can I connect these coaxial cables to anything other than PL259 connectors?

Of course, you can. In fact, with the likes of Ring style and FME Screw-Off End connectors, you are likely to get better output than a PL259 connector.

6. Can I use these cables on scanners?

Yes, you can. Only you’ll have to make sure of using an RG-58 grade connection.

Final Words

Whether you love its company or not, if you happen to own a CB radio, you must get the best CB coax cable for it to avail the best possible service from it. While the best CB coaxial cable is vital for proper signal transmissions, it’s also essential for saving you hefty bucks in the years to come.

Hopefully, this article will help you narrow down your preferences. So take your time, choose the one that suits you the best, and stay worry-free with your CB radio.
