Coaxial cable Rangeful HF240 TNC Male to TNC Female 50 Ω 0.5 m

Rangeful HF240 TNC Male to TNC Female 50 Ω 0.5 m is a short coaxial cable designed to provide a matched 50-ohm connection between TNC-equipped RF devices. At 0.5 m length it offers a compact, shielded link for signal transmission and antenna extensions while minimising standing wave ratio and loss in short interconnect runs. The cable features a TNC male connector on one end and a TNC female connector on the other, making it suitable for direct mating between equipment or for use in test setups and bench configurations where a reliable, impedance-matched jumper is required.

Advantages

The cable provides consistent 50 Ω impedance to maintain signal integrity across radio frequency ranges commonly used in routers, radios and measurement instruments. Its short 0.5 m length reduces insertion loss and limits signal reflections compared with longer leads. The TNC connectors deliver secure threaded connections that resist vibration and provide repeatable mating performance. The construction includes shielding to reduce external interference and ensure stable RF performance in typical indoor and lab environments.

Suitable for

• Connecting antennas to routers, modems or radio transceivers
• Short RF interconnects in test benches and measurement setups
• Replacing or extending TNC-equipped cable runs in compact installations
• Use with RF adapters or pigtails to adapt equipment with TNC interfaces

Key specifications

• Characteristic impedance: 50 ohm
• Connector type: TNC male to TNC female (threaded)
• Length: 0.5 m
• Cable type: coaxial, shielded
• Typical use: RF signal transmission and antenna extension

How to use

Inspect both TNC connectors and mating ports for cleanliness and damage before connecting. Align the TNC male and female connectors, engage the thread and hand-tighten until snug; avoid over-tightening with tools to prevent connector damage. Route the cable to avoid sharp bends and mechanical strain; maintain gentle bend radii consistent with typical coaxial cable practice. For measurement work, place the cable in the same orientation and routing used during calibration to preserve consistent results.

Usage recommendations

Store the cable coiled without tight loops and protect connector ends with caps when not in use. For installations exposed to movement or vibration, periodically check thread engagement and connector condition. If higher frequency performance or lower loss is required over longer distances, consider a cable with appropriate specifications for that application.
