Ullnosoo CB Coax Cable 100ft RG8X PL-259 to FME

Ullnosoo CB Coax Cable 100ft is a flexible, low-loss RG8X coaxial lead with PL-259 to FME connectors and a waterproof boot designed for reliable antenna connections in vehicles, marine, and HAM setups.

This 100-foot Ullnosoo RG8X cable combines a pure copper center conductor, dual shielding, and robust outer jacket to reduce signal degradation over long runs. It ships with a removable UHF (PL-259) coupling and an FME female termination protected by a waterproof boot and extended heat-shrink reinforcement. The construction balances flexibility for routing in tight spaces with durability for outdoor and mobile use.

How does this cable keep transmissions strong over long runs?

The RG8X core uses a solid copper conductor plus aluminum foil and tinned-copper braid that lower resistance and interference. Together these layers maintain better signal-to-noise performance than cheaper single-shield cables, especially across 100 feet.

• Pure copper inner conductor for improved conductivity
• Dual shielding (foil + braid) to reduce RF leakage and noise
• Low-loss characteristics suitable for CB, HAM, and VHF frequencies
• Weather-resistant PVC jacket for outdoor longevity

Will it fit my vehicle or cramped antenna location?

Yes — the cable is engineered for easy routing in constrained areas. A removable UHF-style PL-259 connector detaches when space is limited, letting you snake the cable through tight channels before reattaching the connector for a secure finish.

• Highly flexible RG8X core for tight bends without kinking
• Removable PL-259 UHF connector for installation freedom
• 2.2-inch heat-shrink reinforcement at critical joints prevents separation
• Compact FME female termination for slim mounting points

How durable and weatherproof are the connectors and joints?

The connectors combine nickel-plated copper shells with gold-plated center pins to limit corrosion and maintain contact quality. A waterproof boot covers the FME end and long heat-shrink tubing reinforces the cable-to-connector transition, reducing wear from movement and environmental exposure.

• Nickel-plated solid copper shell for corrosion resistance
• Gold-plated brass center pin for reliable conductivity
• Waterproof boot for outdoor connector protection
• Extended heat-shrink tubing to prevent joint stress and moisture intrusion

What equipment and uses is this cable compatible with?

This 100 ft RG8X lead is a multi-purpose antenna cable that supports CB radios, amateur HAM rigs, VHF setups, and test gear like SWR meters and antenna analyzers. Its connector pair and robust shielding make it suitable for mobile, marine, and fixed-station installations.

• Works with CB, HAM, and VHF transceivers and antennas
• Compatible with SWR meters, tuners, dummy loads, and analyzers
• Designed for vehicle, marine, and portable field use
• Good choice for installers and hobbyists needing long runs

Who is this product for? If you need a long, flexible coax run that balances low signal loss with rugged, weatherproof connectors, this Ullnosoo 100ft RG8X cable is a practical choice. Ideal users include truck and RV owners wiring roof or rack antennas, amateur radio operators extending feedlines to remote mounts, marine technicians adding external antennas, and field testers requiring durable leads for SWR or analyzer work. The removable PL-259 feature and reinforced joints make it a user-friendly option for both professional installers and DIY enthusiasts seeking reliable antenna performance in demanding environments.
