Coaxial cable Rangeful HF240-RPTNCM-NM-0.3 — N male to RP-TNC male, 0.3 m

This Rangeful HF240-RPTNCM-NM-0.3 coaxial cable is a 0.3 m RF jumper with an N male connector on one end and a reverse-polarity TNC (RP-TNC) male connector on the other. It is intended for short, low-loss signal linking between equipment with N and RP-TNC ports, such as antennas, routers, modems and test instruments. The compact length reduces signal attenuation and clutter in rack- and bench-top setups while maintaining consistent RF performance across the cable.

Advantages

The cable provides a secure mechanical connection with threaded N and RP-TNC interfaces for reliable RF transmission. Its short 0.3 m length minimizes insertion loss and potential impedance mismatches compared with longer leads. The coaxial construction offers shielding against external interference and supports stable signal transfer in typical Wi‑Fi, cellular, GNSS and RF testing frequency ranges. The connectors are factory-mounted to ensure consistent impedance and repeatable performance.

Suitable for

• Connecting antennas to routers, modems or cellular gateways
• Linking RF test equipment and measurement instruments in lab setups
• Short jumper between panel-mounted N ports and devices with RP‑TNC male ports
• Temporary or permanent connections in installations requiring a compact RF jumper

Key specifications

• Cable type: coaxial RF jumper
• Length: 0.3 m
• Connector A: N male (threaded)
• Connector B: RP‑TNC male (reverse-polarity threaded)
• Impedance: 50 Ω
• Typical use: RF signal linking for antennas, routers, modems, test equipment

How to use

Align the threaded N male connector to the mating N female port and gently hand-tighten until finger-tight; avoid over-tightening with tools to prevent damage. Align and thread the RP‑TNC male connector into the corresponding RP‑TNC female port and hand-tighten. Verify that connectors are fully seated and that cables are routed to avoid sharp bends or strain at the termination points. For test setups, connect the cable between the instrument and device under test, then power equipment and perform measurements following instrument procedures.

Usage recommendations

Avoid excessive bending near the connectors and protect the cable from mechanical strain or crushing. Use only compatible 50 Ω ports and inspect connectors for damage or debris before use. For outdoor or permanent installations, consider weatherproofing the connection point and selecting a cable length appropriate for minimal loss.
