Coaxial cable Rangeful HF400-RPTNCM-SM-2 2 m, SMA male to RP-TNC male, UltraFlex

The Rangeful HF400-RPTNCM-SM-2 is a 2 m UltraFlex coaxial jumper with an SMA male connector on one end and a reverse-polarity TNC (RP-TNC) male connector on the other. Built for RF signal routing, this cable maintains consistent 50 Ω impedance and offers the mechanical flexibility required for tight routing in test benches, racks, and equipment housings. The jumper is intended for temporary and semi-permanent links in wireless systems, measurement setups, and device-to-device connections where connector compatibility and low signal distortion are important.

Advantages

This UltraFlex coaxial cable provides a low-loss RF path with stable impedance across its length, minimizing reflections and preserving signal integrity. The SMA male to RP-TNC male connector pair allows direct mating with many antennas, radios, test instruments, and wireless modules that use these interfaces. Its 2 meter length offers extended reach without additional adapters, and the flexible construction simplifies routing in confined spaces and around equipment.

Suitable for

• Connecting antennas to routers, modems, and wireless access points with SMA or RP-TNC interfaces
• Laboratory and test equipment setups requiring flexible RF leads
• Inter-device RF links in communication and networking systems
• Field service and troubleshooting where temporary jumper cables are needed

Key specifications

• Cable type: UltraFlex coaxial jumper
• Length: 2 m
• Impedance: 50 Ω
• Connector A: SMA male
• Connector B: RP-TNC male
• Intended frequency range: RF applications (typical for SMA/RP-TNC connectors)
• Construction: flexible outer jacket for tight routing

How to use

Align the SMA male and RP-TNC male connectors with their respective mating ports and tighten by hand or with a suitable torque wrench if specified by the connected equipment. Avoid cross-threading by starting the connection carefully, then secure to the recommended torque for SMA and RP-TNC interfaces when precise RF performance is required. Route the cable to avoid sharp bends, kinks, or repeated flexing at the connector ends. For test and measurement, use a single, direct jumper where possible to minimize additional insertion loss from adapters.

Usage recommendations

Inspect connectors for debris or damage before use, and replace the cable if the center conductor or dielectric appears compromised. Keep bend radius larger than the cable manufacturer’s minimum to maintain performance. When using in measurement setups, document cable usage and warm-up conditions to ensure repeatable results. Store coiled without tight loops to prolong the jacket and connector life.
