Coaxial cable Rangeful RG58-RPSM-NF-5 50 Ω, RG‑58, length 5 m, RPSM to NF connectors

Rangeful RG58-RPSM-NF-5 is a 5 m coaxial cable constructed on an RG‑58 core with 50 Ω characteristic impedance. It features an RPSM (reverse polarity SMA) male-compatible connector on one end and an NF (female N-type) connector on the other, providing a flexible adapter cable for radio frequency (RF) signal transmission. The cable is intended for short-distance, low-loss connections between transceivers, antennas, test instruments and other RF equipment where a compact SMA-style interface must mate to a larger N-type interface.

Advantages

The RG‑58 construction offers a balance between flexibility and electrical performance for frequencies typically used in testing and radio communications. The 50 Ω impedance ensures proper matching with most RF equipment to minimize reflections and power loss. Having an RPSM to NF termination allows direct connection between devices with different connector families without using bulky adapters, while the 5 m length provides room to position equipment in small to medium-sized setups.

Suitable for

• Connecting handheld or bench RF transceivers to N-type antennas or amplifiers
• Laboratory and field test setups where short low-loss interconnects are required
• Temporary installations and equipment prototyping involving SMA-style and N-type ports
• Wireless infrastructure troubleshooting and signal level measurements

Key specifications

• Impedance: 50 Ω
• Cable type: RG‑58 coaxial
• Length: 5 m
• Connector A: RPSM (reverse polarity SMA) male-compatible
• Connector B: NF (female N-type)
• Intended use: RF signal transmission for short distances

How to use

Verify that both connected devices are powered off and that their connectors are clean and undamaged. Align the RPSM connector with the SMA-style socket and gently screw or push until it is seated according to the connector design; then align the NF connector and secure by threading the coupling nut until hand-tight. Avoid over-tightening to prevent damage to connector threads. Route the cable to avoid tight bends, kinks or crushing, maintaining a bend radius suitable for RG‑58 to preserve electrical performance.

Usage recommendations

For best signal integrity, use this cable for short interconnects and avoid long runs where higher-grade low-loss cables are preferable. Periodically inspect connector interfaces for corrosion or wear and replace the cable if shielding or dielectric damage is visible. When connecting to sensitive RF equipment, ensure impedance matching and proper grounding to reduce interference and potential damage.
