Coaxial Cable Rangeful HF240-SM-PL-7 50 Ω, PL259 (UHF) to SMA Male, 7 m

Rangeful HF240-SM-PL-7 is a 7-meter coaxial cable with 50 Ω impedance, fitted with a PL259 (UHF) connector on one end and an SMA male connector on the other. The cable is designed for RF signal transmission between equipment that uses UHF and SMA interfaces and provides a fixed-length, ready-to-install lead for amateur radio setups, antenna connections and test instrumentation requiring a 7 m connection.

Advantages

The cable provides a consistent 50 Ω transmission path over 7 meters, supporting low-loss RF connectivity for typical VHF/UHF amateur radio and measurement frequencies. The PL259 and SMA male terminations allow compatibility between equipment using UHF-threaded connectors and devices with SMA male inputs or adapters. The construction offers straightforward installation and reliable electrical continuity across the specified length without the need for additional adapters in many common setups.

Suitable for

• Connecting transceivers or radio equipment with UHF (PL259/SO-239) and SMA ports
• Linking antennas to tuners, SWR meters or signal analyzers over a 7 m span
• Temporary or permanent test setups in RF labs and field measurements
• Amateur radio stations and portable operating where a 7 m cable run is required

Key specifications

• Impedance: 50 Ω
• Length: 7 m
• Connector A: PL259 (UHF plug)
• Connector B: SMA male
• Intended use: RF signal transmission (VHF/UHF ranges common in amateur and test applications)

How to use

Confirm both devices accept the cable’s connectors: screw the PL259 end to the UHF-threaded socket (matching a SO-239 receptacle) and attach the SMA male end to the SMA female jack by hand until seated. Ensure connectors are clean and threads are engaged without cross-threading; tighten to finger-tight plus a small quarter-turn with an appropriate tool if required, avoiding over-torquing. Route the cable to avoid sharp bends, kinks and proximity to sources of electrical noise. For lab measurements, allow the cable to settle before taking sensitive readings to ensure stable impedance conditions.

Usage recommendations

Inspect connectors for debris or corrosion before use and avoid excessive mechanical stress at the terminations. Use the cable within its intended frequency ranges and maintain gentle bend radii to preserve consistent 50 Ω performance. When storing, coil the cable loosely to prevent tight kinks and protect connector ends with caps or covers if available.
