YOTENKO RG58 50Ω Coax Cable 75ft PL259 to SO239

YOTENKO's 23 m (75 ft) RG58 50Ω coax cable with a PL259 male to SO239 female pair and four adapter types provides a durable, low-loss connection for CB, ham and VHF/UHF radio setups.

If you need a longer, flexible coax run that keeps SWR low and adapts to multiple antenna and radio ports, this 75-foot RG58 cable from YOTENKO is engineered for that role. Built with tinned-copper braid, aluminum foil shielding and a reinforced PL259 assembly with extended heat-shrink, the cable aims to resist corrosion, maintain signal integrity and simplify hookups with the included SMA, BNC and SO239 adapters.

How does this cable reduce signal loss on long runs?

The YOTENKO RG58 is a 50-ohm coax designed with copper conductor, dual shielding (aluminum foil plus tinned-copper braid) and PVC jacketing to limit interference and preserve signal strength across its 23 m length. While RG58 is not as low-loss as larger-diameter coax, careful shielding and quality terminations help minimize degradation for CB, amateur and VHF/UHF use.

• Tinned-copper braid reduces corrosion and preserves conductivity.
• Aluminum foil shield lowers external RF noise pickup.
• Solid copper center conductor maintains consistent impedance.
• 75 ft length balances reach and manageable attenuation for many radio setups.

What connectors and adapters are included, and why do they matter?

This package includes a PL259 male terminated cable to an SO239 female and a 4-piece adapter set: SMA male, SMA female, BNC male and an extra SO239 adapter. The upgraded connectors feature longer heat-shrink tubing and corrosion-resistant plating to keep mechanical and electrical contact reliable under stress or outdoor exposure.

• PL259 to SO239 termination for standard CB and ham antenna interfaces.
• SMA and BNC adapters expand compatibility with handhelds, tuners and test gear.
• Extended heat-shrink improves strain relief at the PL259 junction.
• Salt-spray tested finishes resist oxidation for longer service life.

How tough is the cable for field use and outdoor installations?

The cable assembly combines a flexible PVC jacket with professional crimped connections and longer heat-shrink reinforcement at the PL259, improving resistance to bending fatigue and accidental pulls. The connector plating passed salt-spray testing, which indicates improved resistance to corrosion in marine or coastal environments compared with untreated fittings.

• 6 cm heat-shrink at connectors for better mechanical support.
• Corrosion-tested connector finishes for outdoor durability.
• Flexible jacket that routes easily through conduits and vehicle installations.
• Crimped construction avoids loose center pins and intermittent contact.

Which devices and applications are compatible with this coax set?

Designed for a wide range of radio equipment, this RG58 assembly connects CB radios, amateur HF/VHF rigs, SWR meters, antenna tuners, spectrum analyzers and many marine or mobile systems. The included adapters let you interface with devices using SMA, BNC or UHF/SO239 ports without additional purchases.

• CB and ham antennas, mobile radios and base stations.
• Antenna analyzers, SWR meters, tuners and dummy loads.
• Test gear like VNAs and spectrum analyzers with adapter use.
• Marine and mobile installations where corrosion resistance helps.

Who is this for: Radio hobbyists, mobile installers and technicians looking for a versatile, reasonably low-loss 75 ft coax run with robust PL259 termination and a set of adapters to connect multiple radio and test devices. If you need a long, adaptable cable for home stations, vehicle setups or field testing where durability and connector compatibility matter, this YOTENKO assembly is built to deliver practical, flexible connectivity without requiring immediate upgrade to larger coax types.
