Coaxial cable Rangeful RG58-RPTNCM-SM-7 50 Ω, SMA Male to RP-TNC Male, 7 m

This Rangeful RG58-RPTNCM-SM-7 coaxial cable is a 7 m, 50 Ω RF cable with an SMA male connector on one end and a reverse polarity TNC (RP‑TNC) male connector on the other. It is intended for radio frequency signal transmission between devices that use SMA and RP‑TNC interfaces. The construction follows RG58 characteristics, providing a flexible, shielded connection suited to test setups, antenna links, routers and other radio equipment requiring a reliable 50-ohm transmission line over a moderate distance.

Advantages

The cable offers a standardized 50 Ω impedance for compatibility with RF systems and components that require matched transmission lines. Its 7 m length gives additional reach while maintaining signal continuity between SMA and RP‑TNC interfaces. The combination of SMA male and RP‑TNC male connectors enables direct connection without adapters when matching device ports are available. The RG58-style coax provides flexibility for routing in confined spaces and basic mechanical robustness for typical indoor and sheltered outdoor use.

Suitable for

• Connecting antennas to routers, modems or radio transceivers with SMA and RP‑TNC ports
• Bench testing and measurement setups where 50 Ω continuity is required
• Temporary or semi-permanent installations needing a 7 m RF link
• Hobbyist and professional radio projects using SMA and RP‑TNC interfaces

Key specifications

• Impedance: 50 Ω
• Cable type: RG58-style coaxial
• Length: 7 m
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse polarity TNC male)

How to use

Connect the SMA male end to the device with an SMA female socket and the RP‑TNC male end to the device with an RP‑TNC female socket, ensuring threads are engaged gently and tightened by hand or with an appropriate torque tool if required by the equipment documentation. Route the cable to avoid sharp bends, kinks and sources of mechanical strain; maintain bend radii consistent with RG58 cable practice. For test and measurement work, verify 50 Ω continuity and check for acceptable VSWR using appropriate test equipment before finalizing the installation.

Usage recommendations

Use this cable indoors or in sheltered outdoor locations and avoid prolonged exposure to direct sunlight, heavy moisture or mechanical abrasion. When installing in permanent outdoor environments, consider additional protective measures such as conduit or weatherproof enclosures and periodic inspection of connectors for corrosion or wear.
