Coaxial Cable Rangeful HF240 RP‑TNC Male to RP‑TNC Female 30 cm

Rangeful HF240 RP‑TNC Male to RP‑TNC Female 30 cm is a coaxial jumper cable designed for RF signal connections where reverse‑polarity TNC terminations are specified. The 30 cm length provides a compact link between devices while maintaining reliable shielding and consistent impedance for short patching, antenna extensions or equipment adaptation. This cable is suited to environments where space is limited and a dependable, low‑profile RF connection is required.

Advantages

The cable uses HF240 coaxial construction to ensure stable transmission characteristics and effective electromagnetic shielding. Reverse‑polarity RP‑TNC connectors on both ends allow compatibility with devices requiring RP‑TNC mating, while the short 30 cm length reduces signal loss compared with longer leads and keeps installations tidy. The compact jumper format simplifies connection and disconnection during setup or testing without the need for permanent changes to installed antennas or modules.

Suitable for

• Connecting routers, wireless access points and external antennas that use RP‑TNC terminations
• Short RF patch leads between test equipment and antennas in lab or field diagnostics
• Adapting or extending antenna leads on routers, cellular modems and IoT gateways
• Temporary or permanent installations where a compact, low‑loss jumper is required

Key specifications

• Cable type: HF240 coaxial
• Connector A: RP‑TNC male (reverse‑polarity TNC male)
• Connector B: RP‑TNC female (reverse‑polarity TNC female)
• Length: 30 cm
• Impedance: 50 Ω
• Typical usage frequency range: suitable for common RF and antenna applications (UHF/VHF/Wi‑Fi bands)
• Construction: flexible jumper cable with shielding for reduced interference

How to use

Align the RP‑TNC male and RP‑TNC female connectors with the mating ports on your devices and rotate the coupling nut until it is hand‑tight. Avoid excessive force when tightening to prevent damage to the reverse‑polarity interface. Use the 30 cm jumper for short links between antennas, routers or test instruments; route the cable to minimize sharp bends and avoid kinks, keeping it clear of power cabling to reduce potential interference.

Usage recommendations

For best performance, verify connector compatibility before installation and ensure the mating surfaces are clean. Minimize cable length where possible to reduce insertion loss and maintain consistent grounding. Inspect connectors periodically for wear or corrosion in outdoor or high‑humidity environments and replace the jumper if mechanical damage is observed.
