TUOLNK UHF SO-239 PL-259 Female-to-Female Coax Coupler — 2 Pack
Product description
Type and construction: These are UHF SO‑239 female to PL‑259 female coaxial couplers supplied as a matched pair. Each adapter features the standard SO‑239 female housing to accept PL‑259 male plugs.
Materials and finish: The adapters are machined from brass and finished with a nickel plating for corrosion resistance and reliable conductivity. The visible surfaces show gold and silver tones where plating and mating surfaces appear.
Electrical characteristics: Designed for 50 ohm systems, these low‑loss connectors preserve signal integrity across typical HF/VHF/UHF coax. The central contact and threaded shell ensure a stable RF path when mated.
Included in the package: Two (2) SO‑239 female to PL‑259 female barrel adapters are included. They come ready to use without additional parts or soldering.
Usage and installation: These couplers are meant for quick, tool‑free assembly — hand tightening is normally sufficient. They are commonly used to join two coax cables, adapt a cable to equipment, or add a convenient spare connector for field work, amateur radio stations, CB setups, CCTV runs, wifi radio links and general RF tasks.
Pros
- Solid brass with nickel plating
- Maintains 50Ω, low signal loss
- Tool‑free, quick to install
Cons
- Hand tightening only — limit torque
- Not waterproof without additional sealing
- Bulkier than some low‑profile adapters
VerdictA simple, dependable pair of UHF female-to-female barrel adapters ideal for joining or extending coax runs. Solid brass bodies with nickel plating deliver good conductivity and durability while maintaining 50-ohm impedance for minimal signal loss. They’re straightforward to use — hand-tight, no tools required — and suit antennas, CB/Ham rigs, Wi‑Fi radios, security cameras and other RF equipment.
