Coax cables are not something you’d compare and discuss with your tech-enthusiast friends, but they are important, nevertheless. Without the right cable, a happy day can suddenly take a frustrating turn because a cheap coax will fail sooner or later. Also, it may affect the transmission and reception of the signal even though you are doing everything else right.
For a CB radio, thus, you must purchase the best available coaxial cable and that’s what this article revolves around.

Types of Coaxial Cables
Technology has spoiled us in such a way that there’s always a choice. We can choose from the variety based on our specific needs. The same applies to coax cables as well. The most common types are:
- PL-259: Also known as barrel style coax connections, the PL-259 can plug into all CB radios without problems. It is very common and easy to use. Depending on what you need, you can choose a connection with PL-259 on one end or both.
- Ring: Ring-style coax cables are also very popular for CB radios. They are suitable for tight mounting because of their lower profile. They have a plastic body and are resistant to weather and moisture changes.
- Terminal: These are ring-style connections that suit specific circumstances only. They do not have universal applications. They are very clean and aesthetic with a small o-connection.
Quality variations in coaxial cables
That’s right. There’s no exception here – coaxial cables can also be classified based on quality, much like everything else today.
- RG-8X coax: These are premium coax cables with a stranded center that makes them very reliable. They are thicker and offer better insulation.
- RG-58 coax: These are standard coax cables that provide decent shielding and insulation. They are the most popular coax cables around the world.
Advantages of buying a good coax cable
- Reliable and long-lasting
- Minimal signal loss
- No interference
- Noise-free signals
- Better tuning
- Better transmission quality and range
