Everything about Coax for CB Radios (Part 2)

The coaxial cable is one of the most crucial parts of your radio system, and because of that there are a lot of parts to it! Previously, we discussed a few components about the coaxial cable and now we will cover the primary types of coax cables!  

RG-58: Primarily used for single antenna systems or to connect the radio to a test SWR meter. RG-58 comes in two groups: RG-58 or RG-58/U. RG-58 hold a solid center conductor while RG-58/U has a center conductor made up of around 17 wires twisted together. These cables have an outer diameter of around 0.20”and an RF resistance of 50-ohms.  

RG-8X: Primarily used for single antenna systems or between equipment sets. The cables hold a stranded center conductor with a 0.24” outer diameter, making it more ideal for mobile installations because of its durability. RG-8X uses a special 50-ohm resistance cable, allowing it to handle higher wattages.  

RG-59: Can only be used for dual antenna systems. Like the RG-58, RG-59 comes in two types: RG-59 or RG-59/U. RG-59 hold a solid center conductor vs the RG-59/U which has a center conductor made up of around 19 wires twisted together. These cables tend to have a 0.22” outer diameter and 72-ohms resistance.  

Check out an RG-58 cable, RG-8X, or RG-59 cable here. We have plenty more on our website so we’re sure you’ll find the one for you!
