YOTENKO CB Coax Jumper Cable 3.2ft RG58 PL259 with 2 SO239 Adapters – 50 Ohm

Overview

Meet the YOTENKO CB coax jumper, a purpose-built link for RF setups that value reliability, durability, and signal clarity. This 3.2-foot RG58 jumper balances flexible handling with solid build quality, making it a practical addition to field kits, shack setups, or mobile installations. The design draws on attention to detail and real-world needs, offering possibilities rather than guarantees for improved performance in demanding environments.

Durable, weather-ready construction

Durability starts at the ends. Extended 6 cm heat shrink tubing at both connectors helps keep core and shield aligned, reducing the risk of detachment when the cable is bent or pulled during setup or operation. The construction combines a bare copper core with a braided shield, plus PE, aluminum foil, and PVC layers to create a robust, weather-aware profile that tends to hold up under varying outdoor conditions.

• Extended heat shrink at both ends for secure, long-lasting connections.
• Multi-layer shielding provides strong protection against interference while preserving signal quality.

Signal integrity built for real-world use

The cable’s conductor system emphasizes low loss and effective shielding. A bare copper core paired with a tin-plated braid and multi-layer insulation helps minimize unwanted signal leakage, supporting consistent performance across common CB and amateur radio environments. The shield’s resilient makeup supports dependable operation in weather-exposed settings.

• Bare copper core with braided shield for reliable signal protection.
• Shielding layers are designed to reduce interference from surrounding RF activity.

Rugged connectors and versatile compatibility

Two SO239 female connectors are included, each tested for corrosion resistance through a demanding 48-hour salt spray evaluation and filled with PTFE to improve insulation and reduce potential signal loss. The combination of rugged connectors and a compact, flexible jumper makes it suitable for a wide range of RF tasks, from basic antenna testing to more complex setups involving tuners and meters.

• 2 SO239 female connectors with PTFE insulation for longevity and stable performance.
• Wide compatibility with CB, HAM radios, SWR meters, antennas, analyzers, tuners, receivers, and more.

What’s included and how to use

Package contents reflect practical readiness: a 3.2-foot RG58 jumper cable with PL259 male-to-male ends, plus two SO239 female-to-female adapters. To use, connect the jumper between compatible RF devices, minimize tight bends, and ensure clean, snug mating to maximize the benefits of the shielding and connectors.

• 3.2 ft RG58 jumper cable with PL259 male-to-male connectors and 2x SO239 female-to-female adapters.
