RG8x Coaxial Cable 100 ft, CB Coax Cable, UHF PL259 Male to

The Ullnosoo 100 ft RG8x Coaxial Cable provides a reliable connection for radio operators and vehicle owners setting up 50 Ohm RF systems. Built for applications like CB radios, ham transceivers, and antenna tuners, this cable solves the problem of signal degradation over long runs. It suits anyone needing a ready-to-use line to connect transceivers, dummy loads, or SWR meters across indoor and outdoor spaces.

Signal integrity comes from the internal build, featuring a 17AWG pure copper inner conductor. This thicker core performs better than standard RG58 alternatives, making it suitable for high-powered setups. Double shielding surrounds the core to prevent interference and signal leakage, while the outer PVC jacket remains flexible and waterproof for routing through vehicles like a Jeep Wrangler or running outside to an antenna mast.

Both ends come pre-terminated with fully molded UHF PL259 male connectors. These fittings use nickel-plated brass construction paired with gold-plated center pins to ensure dependable contact across frequencies up to 300 MHz. Because the connectors are pre-molded, you can attach your gear immediately without needing soldering tools or crimpers.

Keep in mind that the connectors are rated for frequencies up to 300 MHz, meaning this cable is not suited for higher-frequency microwave or UHF bands above that threshold. Additionally, at a fixed 100-foot length, managing excess slack is necessary if your setup only requires a short run.

Verdict: The Ullnosoo RG8x cable is a solid choice for CB and ham radio enthusiasts who want low-loss copper transmission over a long 100-foot distance. It offers durable shielding, molded PL259 connectors, and weather-ready construction for home stations and vehicle installations alike.

• Cable Type: RG8x
• Length: 100 feet
• Impedance: 50 Ohm
• Conductor: 17AWG pure copper
• Shielding: Double shielded
• Connectors: UHF PL259 male (nickel-plated brass, gold-plated pins)
• Maximum Frequency: Up to 300 MHz
• Jacket Material: Flexible waterproof PVC

A great fit if you:

• Need a 100-foot 50 Ohm cable for ham or CB radio installations
• Want lower signal loss than typical RG58 coax can provide
• Plan to route antenna cables outdoors or through a Jeep Wrangler
• Connect devices such as SWR meters, dummy loads, or antenna tuners

Consider something else if you:

• Require transmission at frequencies exceeding 300 MHz
• Need a very short patch cable rather than a 100-foot run
