Coaxial cable Rangeful RG58/NM-SM-0.3m 50 Ohm, 0.3 m length

Rangeful RG58/NM-SM-0.3m is a 50 Ohm coaxial cable designed for short RF connections and antenna patch leads. With a 0.3 m length and RG58 impedance, the cable provides a compact, low-loss link between radio equipment and antennas or between test instruments. Connectors follow the NM-SM configuration specified in the model name, offering straightforward mating for compatible devices in lab setups and small installations.

Advantages

The cable delivers a consistent 50 Ω characteristic impedance suitable for many RF applications, helping to minimize signal reflections. Its short 0.3 m length reduces unwanted attenuation and clutter in confined setups. Constructed to the RG58 coaxial form factor, it balances flexibility and shielding for reliable signal transfer in typical low-power RF environments. The NM-SM connector pair simplifies quick connections and disconnections during testing and temporary installations.

Suitable for

• Short patch leads between transceivers and antennas
• Laboratory test setups and measurement rigs
• Temporary or compact RF installations
• Connecting signal generators, receivers, and spectrum analyzers in close proximity

Key specifications

• Impedance: 50 Ohm
• Length: 0.3 m
• Cable type: RG58 coaxial
• Connector configuration: NM-SM
• Typical use: RF signal and antenna connections

How to use

Inspect connectors and cable for visible damage before use. Align and mate the NM and SM connectors with compatible ports, ensuring a secure mechanical fit without excessive force. Route the cable to avoid sharp bends and kinks that can degrade RF performance. For measurement tasks, keep the cable as short as practical and avoid running it parallel to power lines or noisy digital signals to reduce interference.

Usage recommendations

Use this short RG58 cable for low-power RF links and temporary connections where a reliable 50 Ω path is required. For permanent outdoor installations or high-power transmitters, consider cables and connectors rated for environmental exposure and higher power handling. Store the cable coiled loosely and avoid repeated sharp bending at the connector junctions to prolong service life.
