Coaxial cable Rangeful HF240 2 m 50 Ω RP‑SMA male to RP‑SMA female

Rangeful HF240 is a 2-meter coaxial cable with 50 Ω characteristic impedance and reverse-polarity SMA (RP‑SMA) connectors: RP‑SMA male to RP‑SMA female. It is intended for RF signal transmission between devices that use reverse-polarity SMA interfaces, providing a standard impedance match and a practical length for indoor, lab and bench setups. The cable construction supports stable connections for antennas, routers, modems and RF test equipment while maintaining consistent signal behavior across applicable frequency ranges.

Advantages

The cable offers a controlled 50 Ω impedance for minimal signal reflection and compatibility with common RF equipment. RP‑SMA male to RP‑SMA female termination enables use with reverse-polarity antenna ports without adapters. At 2 meters, the length balances reach and manageable signal attenuation for short-range links and laboratory use. The connectors are threaded for secure mechanical coupling and repeatable electrical contact, reducing the risk of intermittent connections during testing or installation.

Suitable for

• Connecting external antennas to routers, access points and modems with RP‑SMA ports
• Lab and bench RF testing where a 2 m cable run is required
• Temporary or permanent interconnects between RF modules and measurement equipment
• Prototyping and development of wireless devices requiring reverse-polarity SMA mating

Key specifications

• Characteristic impedance: 50 Ω
• Cable length: 2.0 m
• Connector type (end A): RP‑SMA male
• Connector type (end B): RP‑SMA female
• Intended applications: RF signal transmission between RP‑SMA interfaces
• Construction: coaxial cable with threaded SMA-style connectors for mechanical stability

How to use

Align the RP‑SMA male and RP‑SMA female connectors with the mating ports and engage the threaded coupling by hand until snug; avoid over-tightening with tools to prevent connector damage. Route the cable to minimize sharp bends and kinks, maintaining gentle curvature to preserve characteristic impedance and reduce insertion loss. For installations with external antennas, verify the antenna gain and orientation after connection and confirm that the connected equipment is powered off during attachment when recommended by the device manufacturer.

Usage recommendations

Store the cable without tight coils or sharp bends to preserve performance. Inspect connector threads and dielectric periodically for wear or contamination and clean with appropriate, non-abrasive tools if necessary. Choose cable routing that keeps it clear of sources of electromagnetic interference and mechanical stress; replace the cable if you observe increased insertion loss or intermittent connections.
