Coaxial UHF adapter cable Rangeful PL259 to SO239 HF240 50 Ω, 0.3 m

Rangeful HF240 coaxial adapter cable with PL259 (male) to SO239 (female) connectors provides a short, reliable UHF join for HF and VHF radio systems. With a 50 Ω impedance and a 0.3 m length, this cable is designed to make compact, low-loss connections between transceivers, antennas and test equipment. The cable supports standard amateur radio and scanner setups and is intended for straightforward plug-and-play installation where a robust UHF interface is required.

Advantages

The Rangeful PL259 to SO239 adapter cable delivers consistent 50 Ω impedance matching to minimize reflections and signal loss in HF and VHF bands. Its short 0.3 m length reduces insertion loss and keeps cable runs tidy, while the UHF connectors provide secure mechanical contact and easy mating with common radio equipment. The cable is suitable for temporary connections and bench testing, offering a compact solution when a short adapter is needed.

Suitable for

• Amateur radio transceivers and base stations
• Handheld and tabletop scanners
• Antenna connections and feedline adaptions
• Equipment testing and bench measurement setups
• Temporary or semi-permanent UHF joins in HF/VHF systems

Key specifications

• Connector A: PL259 (male)
• Connector B: SO239 (female)
• Characteristic impedance: 50 Ω
• Cable length: 0.3 m
• Cable type: UHF coaxial adapter cable
• Typical use frequency: HF/VHF bands

How to use

Connect the PL259 (male) end to the transceiver or radio device output and mate the SO239 (female) end with the corresponding antenna feedpoint or adapter. Ensure connectors are threaded and tightened by hand until snug to maintain proper electrical contact; avoid overtightening. Route the cable to prevent sharp bends and keep it clear of power lines and sources of electromagnetic interference. For testing, use short runs to minimize measurement error and loss.

Usage recommendations

Use this short adapter cable for close-proximity connections and testbench setups. Inspect connector integrity before use and replace the cable if the outer conductor or dielectric shows signs of wear or corrosion. For permanent outdoor installations, choose weatherproofed cabling and connector solutions designed for environmental exposure.
