RG8x Coaxial Cable 100 ft Low Loss CB Coax Cable - Reliable RF Link

In this review of the RG8x Coaxial Cable 100 ft, the conclusion is straightforward: this cable is for radio operators and installers who need a low loss, durable 50 Ohm link for CB and ham radio gear. The single biggest reason to buy is the combination of a thicker 17AWG pure copper conductor and double shielding that reduces signal loss and interference compared with thinner coax options. It is presented as a practical, weatherproof option for mobile installs, antenna analyzers and tuners where signal fidelity matters more than saving a few dollars.

Key Features

• Low loss RG8X: The 17AWG pure copper inner conductor and double shielding work together to minimize signal loss for long runs up to 100 ft.
• High quality connectors: Fully molded nickel-plated UHF PL259 connectors with gold-plated center pins provide reliable connections for frequencies up to 300 MHz.
• Waterproof jacket: The flexible PVC jacket is rated for indoor and outdoor use and resists the elements on mobile or fixed antenna runs.
• Wide compatibility: Designed for any 50 Ohm RF system, it pairs well with CB, ham radio transceivers, antenna analyzers, SWR meters, dummy loads and tuners.
• Durable construction: The thicker conductor and double shielding make the cable mechanically stronger than typical CB coax, so it stands up to repeated routing and installs.

Who It's For

This cable suits ham radio operators, CB users and mobile installers who need a dependable 100 ft run with better loss performance than RG58 or thinner cables. It is particularly useful for those connecting antenna analyzers, SWR meters, tuners or running a CB in vehicles like a Jeep Wrangler where outdoor exposure and flexing occur.

Those who should look elsewhere include users who need ultra-flexible coax for tight, constantly moving joints or very compact radio setups where a smaller diameter RG58 variant is required. Also, if solder-quality on connectors is a primary concern, buyers may want to inspect terminations or choose pre-tested assemblies.

Pros & Cons

Pros

• Low loss performance from a 17AWG pure copper center conductor improves signal strength over long runs.
• Double shielding reduces interference and helps maintain consistent SWR readings with analyzers and tuners.
• Fully molded PL259 UHF connectors with gold-plated pins give solid electrical contact up to 300 MHz.
• Robust PVC jacket and build quality make it suitable for outdoor and mobile installations.

Cons

• The jacket and overall diameter are larger than some RG8x expectations, which can complicate routing through tight spaces.
• Some users noted mixed solder quality on terminations, so careful installation or re-termination may be needed for perfection.

Our Verdict

The RG8x Coaxial Cable 100 ft is a sensible choice for ham and CB operators who prioritize low loss and robust construction over minimal diameter. It delivers good value for long antenna runs, analyzer use and mobile installs, though installers should be prepared for a slightly larger jacket and may choose to re-terminate connectors for the cleanest solder joints.
