Coaxial cable Rangeful SMA male to RP-TNC male RG58/U 50 Ω, 15 m

Rangeful coaxial cable with SMA male to RP-TNC male connectors is built on RG58/U dielectric and specified for 50 Ω systems. The 15 m length provides a flexible connection between devices that require a standard SMA interface on one end and a reverse‑polarity TNC on the other. The cable is intended for RF signal transmission, antenna links, test instruments and wireless equipment where impedance matching and connector compatibility are required.

Advantages

The cable combines a widely used RG58/U coaxial core with precision SMA male and RP‑TNC male terminations to maintain 50 Ω impedance and minimize reflections. Its flexible construction allows routing in confined spaces and simplifies connections between radios, modems and measurement devices. A 15 m length removes the need for immediate proximity between components while preserving signal integrity for many VHF/UHF applications and laboratory setups.

Suitable for

• Extending antenna cables for radio and transceiver systems
• Connecting wireless routers, modems and cellular modules to external antennas
• Linking test and measurement equipment in benchtop environments
• Temporary or semi-permanent installations where SMA to RP‑TNC interface is required

Key specifications

• Cable type: RG58/U coaxial
• Characteristic impedance: 50 Ω
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse‑polarity TNC male)
• Length: 15 m
• Construction: flexible coaxial with dielectric core and shield braid

How to use

Connect the SMA male end to the equipment or antenna with an SMA female socket and attach the RP‑TNC male end to the device or antenna with an RP‑TNC female interface. Ensure connectors are aligned before engaging threads to avoid cross‑threading and tighten by hand; use an appropriate torque wrench if precise torque is required. Route the cable avoiding sharp bends and high‑strain points to preserve the internal conductor and shielding. For best performance, keep joins and adaptors to a minimum and ensure all mating surfaces are clean.

Usage recommendations

Use this 50 Ω SMA to RP‑TNC cable for VHF/UHF signal paths where RG58 performance is acceptable; avoid use at frequencies or in applications requiring low‑loss high‑frequency coax such as critical microwave links. Inspect connectors periodically for wear, and replace the cable if the dielectric or shielding is damaged. For permanent outdoor installations, consider additional weatherproofing at connector interfaces.
