Coaxial cable Rangeful HF240-RPSM-NM-12 12 m 50 Ω RP-SMA male to N male

Rangeful HF240-RPSM-NM-12 is a 12 m coaxial cable with 50 Ω characteristic impedance, terminated with an RP‑SMA male connector on one end and an N male connector on the other. The cable is intended for RF signal transmission between devices that use RP‑SMA and N interfaces, offering extended reach for antenna placement, routers, modems and laboratory equipment while maintaining impedance matching for minimized reflections and stable signal transfer.

Advantages

This coaxial cable provides a long 12 m length that enables flexible device and antenna placement without adding intermediate adapters. With a consistent 50 Ω impedance and factory-installed RP‑SMA male and N male terminations, the cable reduces the need for additional connectors, preserves RF performance across the run, and supports a range of wireless and testing applications. The construction balances flexibility and shielding to allow routing through standard installations while protecting the signal from external interference.

Suitable for

• Connecting routers, modems and access points to external antennas
• Linking measurement and test equipment with RP‑SMA and N interfaces
• Extending cable runs between outdoor or rooftop antennas and indoor radio equipment
• Temporary or permanent RF setups in labs, workshops, or field sites

Key specifications

• Cable length: 12 m
• Characteristic impedance: 50 Ω
• Connector A: RP‑SMA male
• Connector B: N male
• Application: RF signal transmission between RP‑SMA and N interfaces

How to use

Connect the RP‑SMA male end to the device or antenna that accepts RP‑SMA female interfaces and attach the N male end to equipment or antenna ports that accept N female connectors. Route the cable to avoid sharp bends and excessive tension; maintain bend radii recommended for coaxial cables to preserve electrical performance. Ensure both connector threads are hand‑tightened and, where specified by equipment manuals, secured using a torque wrench to avoid over‑tightening and potential damage.

Usage recommendations

For best performance, use this 50 Ω cable in frequency ranges and power levels appropriate for RP‑SMA and N connector systems. Avoid running the cable parallel to strong sources of electromagnetic interference and protect outdoor portions from prolonged exposure to harsh weather unless additional environmental protection is applied. Inspect connectors periodically for corrosion or mechanical wear.
