Coaxial cable Rangeful SMA Male to N Female RG58/U 50 Ω, 3 m

Rangeful coaxial cable SMA Male to N Female RG58/U 50 Ω, 3 m is a 3‑metre RF patch cable designed to connect devices with SMA male and N female interfaces while preserving 50 ohm impedance. Constructed on RG58/U dielectric and shielding, this cable provides a flexible, standard‑length link for antenna connections, radio systems, test instruments and other RF equipment that require consistent signal transfer at 50 Ω.

Advantages

This SMA male to N female cable offers reliable impedance matching with a 50 Ω RG58/U core to minimize reflections and insertion loss in typical RF frequency ranges. The combination of an SMA male and an N female connector enables straightforward mating between small-form-factor equipment and larger outdoor or rack‑mounted antenna ports. The 3 m length balances reach and signal integrity, while the cable’s flexibility simplifies routing in confined setups.

Suitable for

• Connecting indoor RF devices with SMA outputs to outdoor or rack N‑female antenna inputs
• Use with test and measurement equipment that accepts SMA and N connectors
• Temporary or semi‑permanent links in radio systems, repeaters and base stations
• Laboratory setups and prototyping where a 3 m 50 Ω jumper is needed

Key specifications

• Cable type: RG58/U
• Characteristic impedance: 50 Ω
• Connector A: SMA Male
• Connector B: N Female
• Length: 3 m
• Construction: flexible coaxial with standard shielding

How to use

Align the SMA male pin with the corresponding SMA female socket and gently screw the SMA connector until finger‑tight; avoid overtightening with tools to prevent damage. Mate the N female by aligning and threading the N connector nut to the N male port, tightening to a secure, hand‑tight connection and applying a moderate final turn with an appropriate torque tool if required by the installation. Route the cable to avoid sharp bends and compressive loads, keeping bend radius larger than the cable’s specified minimum to maintain RF performance. Ensure connectors are clean and dry before connection to reduce insertion loss and corrosion risk.

Usage recommendations

For optimal performance, use this 50 Ω RG58/U cable within its intended frequency range and avoid repeated flexing near the connectors. When used outdoors or in exposed environments, add appropriate weatherproofing at the N‑connector interface and inspect connections periodically for corrosion. Where higher shielding or lower loss is required, consider thicker coax types or shorter cable runs.
