- Low Loss RG8X Cable: Our RG8X cable is made with pure copper inner conductor, with double shielding to prevent signal leakage, interference and signal loss. Our cable is stronger and more durable than the average CB antenna cables.
- High Quality UHF Connectors: Fully molded nickel-plated brass UHF PL259 connectors with gold-plated center pins, for frequencies up to 300 MHz.
- Waterproof and Easy to Use: With a strong and flexible PVC jacket, it can be used indoors and outdoors.
- Wide Compatibility: These RG8X cables are perfect for any 50 Ohm RF system, like CB ham radio, antenna analyzer, antenna tuner, dummy load, SWR meter, antenna transceiver and so on. It's also great for Jeep Wrangler CB installation.
- Better than RG58, RG8x coax cable has 17AWG thicker pure copper inner conductor, is recommended for high-powered applications or users who simply want the best coax possible.

Detailed Review
The Ullnosoo RG8x Coaxial Cable connects 50 Ohm radio frequency equipment over a 50-foot run without the higher signal loss common to thinner cables. Built for ham operators, CB radio users, and vehicle installations, it provides a ready-to-use link between your transceiver and antenna gear.
Inside, the cable uses a 17AWG pure copper center conductor paired with double shielding. This thicker gauge helps maintain signal strength in higher-powered setups, while the shielding layers block interference and prevent signal leakage. On each end, fully molded nickel-plated brass PL259 UHF male connectors feature gold-plated center pins, supporting frequencies up to 300 MHz.
A durable, flexible PVC outer jacket makes this cable waterproof, allowing you to route it through outdoor setups, home stations, or vehicle cabins such as a Jeep Wrangler. It links directly into CB ham radios, SWR meters, antenna tuners, dummy loads, and antenna analyzers without requiring separate adapters.
Keep in mind that the connectors and cable construction are rated for frequencies up to 300 MHz, so it is not suited for higher UHF or microwave bands. At 50 feet in length, you will also need enough space along your run to manage any remaining slack.
Verdict: The Ullnosoo RG8x cable is a dependable choice for anyone needing a pre-assembled 50-foot line for 50 Ohm ham or CB radio gear. It offers solid shielding, a thick copper core, and durable outdoor-ready construction for frequencies under 300 MHz.
