Coaxial cable Rangeful HF400-RPTNCM-SM-7 SMA male to RP-TNC male, 7 m, UltraFlex

The Rangeful HF400-RPTNCM-SM-7 coaxial cable connects an SMA male connector to an RP‑TNC male connector over a length of 7 meters. Designed using Rangeful's UltraFlex construction, the cable provides RF signal transmission for setups that require a longer, more flexible interconnect between devices with SMA and reverse-polarity TNC interfaces. It is intended for use in test benches, temporary installations, antenna extensions and similar applications where a pliable cable routing is beneficial.

Advantages

The UltraFlex construction improves bendability and reduces stress at connector junctions compared with standard coaxial leads, easing installation in cramped or frequently reconfigured environments. The fixed SMA male to RP‑TNC male connector pairing eliminates the need for adapters when connecting equipment that uses these specific interfaces. The 7 m length allows flexible placement of antennas and test instruments while maintaining a reliable RF path for common frequencies supported by HF400-type coaxial designs.

Suitable for

• Extending antenna connections where SMA to RP‑TNC mating is required
• Temporary or portable RF test setups and measurement benches
• Lab and development environments with frequent cable re-routing
• Field installations requiring a flexible, longer RF lead

Key specifications

• Cable type: UltraFlex coaxial construction optimized for bendability
• Connectors: SMA male to RP‑TNC male
• Length: 7 meters
• Intended use: RF signal transmission between compatible connector types
• Typical applications: antenna extension, test and measurement, temporary installations

How to use

Connect the SMA male end to the SMA female port and the RP‑TNC male end to the corresponding RP‑TNC female port, ensuring threads engage smoothly without cross‑threading. Route the cable to avoid sharp bends and excessive tension; the UltraFlex design permits tighter radii than standard coax but proper strain relief at connector ends is recommended. For test and measurement setups, secure the cable to avoid movement during measurements. When disconnecting, hold the connector body rather than pulling on the cable jacket to prevent stress on the terminations.

Usage recommendations

Store the cable coiled loosely and avoid tight wraps that create sharp bends. Inspect connector interfaces for debris or damage before use. For critical measurements, keep cable runs as short as feasible and avoid routing near high‑power sources or strong electromagnetic interference. Replace the cable if connector integrity or shielding appears compromised.
