YOTENKO RG58 50Ω Coax Cable 49.2 ft PL259 + Adapter Kit

YOTENKO’s RG58 50-ohm coax kit pairs a 49.2-foot PL259-terminated cable with four upgraded UHF/SMA/BNC adapters for reliable RF connections in CB, ham and two-way radio setups.

This kit combines a low-loss RG58 coaxial run with heavy-duty PL259 (UHF male) connectors and a set of four versatile adapters (UHF female to SMA male/SMA female/UHF male/BNC male). The cable is built with tinned copper braid, aluminum foil shield and solid copper center conductor, plus extended heat-shrink on the connector boots to improve strain relief and corrosion resistance. It’s intended for antenna feeds, SWR meters, tuners and general RF test and field use where a 50-ohm line and adaptable connector options are needed.

How does this cable maintain signal quality over a 49.2-foot run?

The RG58 construction reduces insertion loss while keeping flexibility for routing through vehicles or into a shack. The solid copper core and dense tinned braid shield limit signal leakage, and the aluminum foil layer further isolates the inner conductor from interference.

• 50-ohm impedance optimized for HF/VHF applications
• Tinned copper braid + aluminum foil for effective RF shielding
• PVC jacket and PE dielectric for environmental durability
• Low-loss behavior suitable for moderate-range antenna feeds

Are the PL259 connectors and adapters durable enough for field use?

YOTENKO upgraded the connectors with improved plating and an extended 6 cm heat-shrink sleeve to reinforce the cable-to-connector transition. The adapters have passed salt-spray testing and are designed to resist corrosion and remain mechanically secure under normal bending and handling.

• Extended heat-shrink for better strain relief and pull protection
• Salt spray environmental test verified for corrosion resistance
• Crimped connections for consistent mechanical integrity
• Adapter pack expands compatibility without re-terminating the cable

Which devices and scenarios will this kit work with?

This 50-ohm line and adapter set fits a broad range of amateur and mobile radio equipment. Use it for CB and ham antennas, SWR meters, tuners, marine radio installations, portable field days, and as a test lead for analyzers and dummy loads.

• Compatible with CB, HF/VHF ham radios, two-way radios, SWR meters
• Adapters enable connections to SMA, BNC and alternate UHF interfaces
• Useful for antenna analyzers, VNAs, spectrum analyzers and tuners
• Works in vehicle installs, portable setups and bench testing

How easy is it to install and adapt to different rigs?

The cable arrives ready with PL259 (UHF male) terminations; adapters convert to other common RF interfaces without soldering. The robust heat-shrink boots and crimped connectors make handling and repeated connect/disconnect cycles straightforward for home or field technicians.

• Plug-and-play PL259 ends for radios and antenna mounts
• Four adapters in the kit remove the need for extra cable runs
• Crimped connectors reduce setup time versus DIY termination
• Flexible jacket eases routing through vehicle and station spaces

Who is this for: Radio hobbyists, mobile installers, field operators and bench technicians who need a dependable 50-ohm feed line with broad connector compatibility will find this YOTENKO kit useful. It’s well suited for users who value a ready-made coax run with improved connector strain relief and a set of adapters to bridge between PL259 and SMA/BNC/UHF interfaces without custom termination.
