TruckSpec 18' RG-58A/U Coaxial Cable with PL-259 Connectors

This 18-foot RG-58A/U cable from TruckSpec is built for reliable radio connections where flexibility and shielding matter. It features a stranded center conductor for easier routing in vehicles and tight spaces, and molded PL-259 connectors that help resist moisture and mechanical strain. With 95% braid coverage the cable minimizes RF leakage and interference, supporting clearer transmissions for CB, amateur, and two-way radio setups.

How does this cable improve CB and two-way radio performance?

Better shielding and a secure connector fit reduce noise and signal loss along the feedline. The stranded conductor remains flexible so bends and runs through vehicle panels are less likely to damage the core, preserving consistent SWR and audio quality.

• 95% braided shield blocks external RF and reduces cross-talk.
• Stranded center conductor resists breakage during routing.
• Molded PL-259 ends ensure stable connections to SO-239 antenna studs.
• 18-foot length balances reach with manageable signal attenuation.

Are the PL-259 connectors suitable for outdoor use and moisture protection?

The PL-259s are molded with a protective overmold that helps seal the soldered or crimped joint against moisture ingress and mechanical stress. While the cable improves weather resistance at the connector, adding an external weather boot or silicone tape at exposed junctions increases long-term outdoor durability.

• Molded connector bodies limit water entry at the cable-connector interface.
• Robust strain relief reduces fatigue at common bend points.
• Compatible with standard SO-239 antenna studs found on CB antennas and many base stations.

How easy is it to install and route this 18' coax cable?

The stranded core and supple jacket make the cable easy to route through vehicle cabins, under dash panels, or along masts without kinking. Its length accommodates most truck or car roof mounts and leaves extra slack for neat fastening and future re-routing.

• 18-foot length suitable for most vehicle-mounted antennas and mobile rigs.
• Flexible jacket simplifies tight bends and cable management.
• Standard PL-259 ends plug directly into SO-239 antenna mounts—no adapters needed for common installations.

What are the technical highlights and compatibility notes?

This RG-58A/U cable is a widely used coaxial type for VHF/UHF and CB frequencies; the 95% braid and stranded conductor strike a balance between shielding and flexibility. It is ideal for antenna-to-radio runs where an 18-foot length is appropriate, but consider longer or lower-loss cable types if you need very long runs or minimal signal drop.

• RG-58A/U spec: industry-standard impedance for CB and many VHF/UHF uses.
• 95% shield coverage for reduced RF leakage and improved signal integrity.
• Molded PL-259 connectors for direct connection to SO-239 antenna studs.

Who is this for: The TruckSpec 18' RG-58A/U cable is aimed at mobile radio users—truckers, off-roaders, amateur radio hobbyists and two-way radio operators—who need a durable, weather-resistant feedline that balances flexibility, protection, and performance for typical vehicle-mounted antenna setups.
