RG8X Coaxial Cable 100ft Low Loss 50 ohm RG 8X Cable - Low SWR

In this review the RG8X Coaxial Cable 100ft is presented as a practical upgrade for anyone wanting lower loss and more robust construction than standard RG-58. The bottom line: this cable is for radio amateurs, installers of cell signal boosters and WiFi repeaters, or anyone who needs a 50 ohm run with minimal signal loss over distance. Our review highlights the cable's low SWR, solid copper conductor and waterproof PVC jacket as the single biggest reasons to choose it for outdoor and higher-power RF use.

Key Features

• Low loss and low SWR: The cable keeps signal loss down compared with RG-58 and maintains a SWR under 1.15 for cleaner transfer at higher frequencies.
• 50 ohm compatibility: Works with any 50 ohm RF system, so it is suitable for cell phone signal boosters, WiFi repeaters, CB and ham radio setups without impedance mismatch concerns.
• Solid conductor construction: A solid copper inner conductor and foam dielectric deliver consistent performance and good conductor quality for radio use.
• Durable outer jacket: The waterproof PVC jacket resists outdoor elements and can be bent or strapped during installation without easily inducing interference.
• Length and convenience: The 100 ft length covers long runs for antennas and repeaters, reducing the need for extra connectors that can add loss.

Who It's For

This cable is aimed at amateur radio operators, installers of signal boosters and WiFi extenders, and hobbyists who need a longer low-loss 50 ohm cable run for outdoor antennas or testing equipment. Its lower loss compared with RG-58 and a SWR under 1.15 make it a sensible choice where signal quality over distance matters.

Those who need extreme flexibility for tight bends or frequent re-routing should look elsewhere, since customer feedback notes the cable is on the stiffer side. Also, buyers expecting a pre-wound wood spool should note the package includes the bare 100 ft cable without the pictured spool.

Pros & Cons

Pros

• Low loss and low SWR improve signal transfer for higher frequency or longer runs.
• Solid copper conductor and substantial braid offer good conductor quality and reliable performance.
• Waterproof PVC jacket provides durable outdoor protection and installation resilience.
• Compatible with a wide range of 50 ohm connectors and RF systems, reducing the need for adapters.

Cons

• Relatively stiff cable can be harder to route in tight spaces and may challenge installers seeking maximum flexibility.
• The product ships as loose cable, not on the pictured wooden spool, which can affect handling during installation.

Our Verdict

The RG8X 100 ft cable is a sensible, value-conscious upgrade over RG-58 for anyone needing reliable 50 ohm runs outdoors or for higher-power radio use. It combines low loss, a solid copper conductor and a waterproof jacket to deliver good long-run performance; purchase it if you prioritize signal quality over maximum flexibility and want durable cable for antennas and boosters.

Frequently Asked Questions

Is this cable suitable for ham radio antennas?
Yes. The RG8X 50 ohm construction and low SWR make it appropriate for many ham radio antenna installations, especially where lower loss over distance is needed.

Will it work with my cell signal booster?
Yes. It is compatible with 50 ohm RF systems used by most cell signal boosters and WiFi repeaters, though you may need the correct connector type for your booster.

Does the cable come on a wooden spool?
No. The package includes the 100 ft cable only; the wooden spool shown in some images is not included.
