Coaxial cable Rangeful SMA Male to SMA Female RG58 50 Ω 0.3 m

Coaxial cable Rangeful SMA Male to SMA Female RG58 50 Ω 0.3 m is a short RF patch lead designed for reliable connections between devices fitted with SMA interfaces. The cable uses RG58 conductor and maintains a characteristic impedance of 50 ohms across a compact 0.3 m length, offering a balance of flexibility and signal integrity for antenna connections, test setups and short interconnects where a small footprint is required.

Advantages

This SMA male to SMA female coaxial cable provides consistent 50 Ω impedance matching suitable for many RF systems, minimizing reflections at the connection. The short 0.3 m length reduces insertion loss compared with longer leads and helps keep installations tidy in constrained spaces. RG58 construction delivers adequate shielding and mechanical flexibility for routine use in labs, field setups and consumer RF equipment.

Suitable for

• Connecting antennas to radio modules or routers with SMA connectors
• Short patch lead for RF test and measurement equipment
• Replacing or extending short SMA coax runs in compact installations
• Prototyping and bench setups where low-loss, short interconnects are needed

Key specifications

• Connector types: SMA male to SMA female
• Cable type: RG58
• Impedance: 50 Ω
• Length: 0.3 m
• Typical use: RF signal transmission for antennas and test equipment

How to use

Verify that both devices support SMA connectors and a 50 Ω transmission line before connecting. Align the SMA male pin with the female receptacle and hand-tighten the SMA coupling nut; avoid over-tightening to prevent damage to threads or center conductors. Route the cable to minimize sharp bends and avoid kinking; maintain gentle curves to preserve impedance and shielding performance. For test setups, connect the cable between instrument port and DUT or antenna and confirm signal continuity and expected return loss with a network analyzer if available.

Usage recommendations

For best performance, use this short RG58 SMA cable where low insertion loss and compact routing are priorities. Avoid repeated heavy flexing at connector junctions and keep the cable clear of high-power or noisy digital lines to minimize interference. If operating at higher frequencies or where tighter VSWR is required, consider higher-spec coax types designed for those ranges.
