PL259 100ft UHF Coax Cable - Low Loss RG58 for CB and Ham Radio

In this review the PL259 100ft UHF coax cable is examined for amateur radio operators, CB users, and anyone needing a long, flexible RG58 jumper. The single biggest reason to consider it is its low loss braid and solid construction that preserve signal across distance, making it a practical choice for SWR meter work and antenna runs. The review looks at build, connectors, and real-world suitability rather than marketing claims to help you decide if this cable fits your installation needs.

Key Features

• Low loss braid: A high density tinned copper braid minimizes signal attenuation so RF energy is retained over the 100ft run, useful for VHF and UHF work.
• Durable jacket and flexibility: The RG58 core is flexible enough for routing and installations where the cable needs to bend without kinking.
• Solid inner conductor: A solid copper center conductor supports stable connections and consistent conductivity for radio equipment.
• Waterproof connector joint: A 2.2in heat shrink tube with lined adhesive seals the joint, reducing the chance of moisture ingress and connector pull out.
• Nickel plated connector shell: The PL259 shell is copper with nickel plating for improved oxidation and corrosion resistance on the UHF male end.
• Wide compatibility: Works with CB, ham radio, SWR meters, antenna analyzers, and other devices that accept UHF PL259 terminations.

Who It's For

This cable is well suited for amateur radio operators and CB users who need a long RG58 jumper for an antenna feedline, SWR checks, or temporary installs where flexibility and low loss matter. It is also a practical choice for marine VHF setups and bench testing with antenna analyzers or SWR meters.

Those who require extremely low loss over long permanent runs or higher power handling should look to heavier coax types; likewise, if you need factory-certified soldered connectors or bulkhead-ready assemblies, a custom-made cable may be preferable.

Pros & Cons

Pros

• Low signal loss over 450MHz due to the dense tinned copper braid, maintaining stronger received and transmitted signals.
• Flexible RG58 construction makes routing and temporary setups straightforward without excessive stiffness.
• Waterproof 2.2in heat shrink at the connector reduces the risk of connector pull out and moisture damage.
• Solid copper center conductor and nickel plated shell improve longevity and reliable connections.

Cons

• Some customers report mixed build quality at solder joints, so inspect each end before permanent installation.
• As RG58 at 100ft, it is higher loss than larger coax types for very long permanent runs.

Our Verdict

The PL259 100ft RG58 coax is a solid, value-oriented cable for CB and ham radio users who need a flexible, low loss jumper for testing, SWR checks, or semi-permanent runs. Its waterproofed connector joint and quality materials make it a practical everyday option, though installers wanting the lowest possible loss for long-term permanent feeds should consider heavier coax types.

Frequently Asked Questions

Is this cable suitable for SWR meter checks?
Yes. The low loss braid and stable construction make it suitable for SWR meter use and antenna analyzer hookups.

Will the connector resist corrosion outdoors?
The nickel plated connector shell and heat shrink adhesive joint improve resistance to oxidation and moisture, but outdoor exposed runs should be further protected in harsh environments.

Can I use this for high power transmissions?
It is acceptable for typical CB and amateur power levels, but for sustained high power or very long permanent runs, a thicker low loss coax is recommended.
