Coaxial cable Rangeful RP‑SMA Male to RP‑SMA Male RG58/U 50 Ω 3 m

Rangeful coaxial cable RP‑SMA Male to RP‑SMA Male RG58/U 50 Ω 3 m is a shielded RF cable designed for connecting devices with RP‑SMA interfaces. Constructed on RG58/U dielectric with 50 ohm characteristic impedance and a three‑meter length, the cable supports stable signal transfer for wireless equipment, routers, antennas, modems and RF test devices. Both ends feature RP‑SMA male connectors for straightforward plug‑and‑play installation, while the shielding reduces external interference in everyday indoor and lab environments.

Advantages

The cable offers consistent 50 Ω impedance matching across its length to minimise reflections and signal loss in RF links. RG58/U dielectric and copper shielding provide a balance of flexibility and electrical performance, making routing and installation easier in tight spaces. Gold‑plated RP‑SMA male contacts enhance corrosion resistance and ensure reliable contact over repeated mating cycles. The three‑metre length gives additional reach for flexible device placement without requiring adapters.

Suitable for

• Connecting routers and access points to external antennas
• Linking modems and RF front‑end modules in lab setups
• Extending antenna placement for better signal reception
• Temporary or permanent connections in RF test benches
• Integrating wireless devices with RP‑SMA ports in home or office networks

How to use

Align each RP‑SMA male connector with the RP‑SMA female port on the devices and carefully thread the connectors by hand until snug; avoid excessive torque to prevent connector damage. Route the cable to minimise sharp bends and avoid running it parallel and close to mains power cables to reduce potential interference. For temporary measurements on test equipment, secure the cable gently to prevent strain on the connectors. For permanent installations, use cable clamps or tie wraps at strain‑relief points while keeping connectors accessible for maintenance.

Usage recommendations

Inspect connectors for debris before mating and keep contact surfaces clean. Avoid repeated high‑torque tightening; hand‑tighten until firm. For best RF performance, maintain gradual bends with a radius larger than the cable diameter and replace the cable if the outer jacket or connectors show visible wear or damage.
