Coaxial cable Rangeful HF400-SM-PL-2 50 Ohm, SMA male to PL259 UHF, 2 m

Rangeful HF400-SM-PL-2 is a 2 m, 50 Ohm coaxial cable with an SMA male connector on one end and a PL259 UHF connector on the other. It is designed for HF and VHF radio applications and provides a matched 50 Ω connection between devices with SMA and UHF PL259 interfaces. The cable combines flexibility and shielding appropriate for short interconnections between transceivers, scanners, antenna feeds and other radio equipment where a compact, reliable jumper is required.

Advantages

The cable delivers a consistent 50 Ohm impedance along its length to minimise signal reflections and losses at HF and VHF frequencies. Flexible construction and durable connector housings allow for convenient routing and repeated connection cycles without rapid wear. The combination of SMA male and PL259 UHF connectors enables direct mating to common handhelds, mobile transceivers and base equipment with PL259 (SO-239) sockets. The 2 m length provides reach for typical bench or vehicle installations while remaining manageable and easy to coil for storage.

Suitable for

• Connecting amateur radio transceivers to antennas or antenna tuners
• Linking scanners, receivers or test equipment to external antennas
• Temporary or semi-permanent mobile and base station installations
• HF and VHF bench testing and troubleshooting where a short jumper is needed

Key specifications

• Characteristic impedance: 50 Ohm
• Length: 2 metres
• Connector A: SMA male
• Connector B: PL259 UHF (fits SO-239)
• Intended frequency range: HF and VHF bands (suitable for typical amateur and scanner bands)
• Cable type: flexible coaxial suitable for short interconnects

How to use

Inspect connectors and cable for visible damage before use. Ensure the SMA male is aligned and threaded carefully into the mating SMA female to avoid cross-threading; tighten by hand and finish with a light turn using an appropriate torque wrench or finger-tight if no torque tool is available. Mate the PL259 connector to the SO-239 socket by aligning the centre pin and screwing the outer body down until secure. Route the cable to avoid sharp bends and pinching; maintain gentle bend radii to preserve characteristic impedance. For installations exposed to weather, protect connectors with suitable sealing tape or boots to prevent moisture ingress.

Usage recommendations

Use this cable for short runs where flexibility and convenient connector types are required. Avoid extended runs at higher frequencies where insertion loss may increase; for long cable runs select a lower-loss feedline. Periodically check connectors for corrosion or loose fittings and replace the cable if shielding or centre conductor integrity is compromised.
