  • Nickel-plated brass connectors resist corrosion in mobile installs
  • Gold-plated brass contacts maintain low-loss signal transfer
  • Three-foot RG58 cable suits compact vehicle routing

Cable purpose and users

This 3 ft UHF coaxial cable connects a PL-259 male plug to an SO-239 female bulkhead jack. It serves CB radio, amateur radio, mobile and handheld transceivers, two-way radios, public scanners and FM transmitters needing a short, shielded link. The 50 ohm impedance matches standard radio equipment.

Practical limits of UHF interface

The UHF connector pair is rated for 50 ohm systems and works reliably at HF and VHF frequencies. At higher UHF bands the interface can introduce measurable loss and VSWR degradation, so it is not suited for microwave or precision test applications. RG-58 construction adds further attenuation on long runs.

Installation notes

The bulkhead SO-239 end requires a panel cut-out and a securing nut; ensure the mounting surface is flat and thick enough for the threads. Over-tightening the PL-259 coupling can damage the centre pin or strip the threads. Verify polarity and continuity before permanent installation.

Questions about this item

Which cable type should I choose between the RG58 and RG316 versions?

The product title lists RG58 while the highlights mention RG316; both are 50 ohm coaxial cables with the same UHF PL-259 male to UHF SO-239 female bulkhead connectors and 3 ft length.

What does the 50 ohm impedance mean when I connect this to my radio?

It matches the standard 50 ohm impedance of CB, amateur and two-way radios so signals pass without reflection loss across the 3 ft run.

What does the UHF PL-259 to SO-239 interface cap in practice?

The UHF PL-259 male and SO-239 female bulkhead connectors are rated for HF and VHF use typical of CB and amateur bands; the 3 ft RG58 cable keeps insertion loss low on those frequencies.
