Coaxial cable Rangeful RP-SMA Male to RP-SMA Male RG58/U 50 Ω 0.3 m

This Rangeful coaxial cable has RP-SMA male connectors at both ends and uses RG58/U construction with a characteristic impedance of 50 Ω. At 0.3 m length, the cable provides a short, flexible RF connection for antenna extensions, test setups, routers and other wireless equipment that require RP-SMA terminations. The cable’s compact size and standard RF connector type make it suitable for close-proximity connections where signal integrity and mechanical compatibility are important.

Advantages

The RG58/U dielectric and braid construction delivers consistent 50 Ω impedance and predictable performance across commonly used RF frequencies. RP-SMA male to RP-SMA male terminations provide a secure mechanical and electrical connection to devices and antennas with reverse-polarity SMA interfaces. The short 0.3 m length reduces insertion loss and signal degradation for near-field connections while remaining flexible enough for routing in tight spaces. The cable’s construction is compatible with many consumer and professional wireless devices designed for 50 Ω coaxial connections.

Suitable for

• Connecting antennas to routers, modems and access points with RP-SMA ports
• Short RF test leads and lab measurement setups
• Extending or repositioning small wireless devices and external antenna leads
• Temporary or permanent connections in IoT gateways and radio modules

Key specifications

• Cable type: RG58/U coaxial
• Connector type: RP-SMA male to RP-SMA male
• Characteristic impedance: 50 Ω
• Length: 0.3 m
• Typical use: RF and antenna connections for wireless equipment

How to use

Align each RP-SMA male connector with the mating RP-SMA female jack on the device or antenna and carefully screw the connector onto the threaded port until hand-tight. Avoid over-tightening to prevent damage to the connector threads or device housing. Route the cable to minimize sharp bends and avoid pinching; keep the cable away from strong EMI sources where possible. For test setups, verify continuity and expected insertion loss with appropriate RF test equipment after installation.

Usage recommendations

Use this short 0.3 m RG58/U cable for close-range connections to reduce loss. For outdoor or permanently installed antennas consider weatherproofing the connection and checking connector tightness periodically. If operating at higher RF power or at frequencies outside typical Wi‑Fi/ISM bands, verify that the cable’s loss and power handling are compatible with your application.
