Coaxial cable Rangeful HF240 TNC Male to TNC Female 50 Ω, 10 m

Rangeful HF240 coaxial cable with TNC male to TNC female connectors is a 10 m, 50 Ω RF cable designed for reliable signal transmission and threaded antenna connections. The cable provides consistent impedance over its length and uses a secure TNC threaded interface for stable mechanical and electrical coupling in environments where a screw-on connector is preferred over push-fit types. It is intended for use with radio equipment, test instruments and network devices that require 50 ohm cabling.

Advantages

The HF240 cable combines a standardized 50 Ω impedance with robust TNC male to TNC female connectors to minimize reflections and signal loss across the 10 m run. Its threaded connector design reduces the risk of accidental disconnection and maintains a solid RF contact under light mechanical stress. The cable assembly is manufactured to provide consistent electrical characteristics suitable for antenna feeds, instrumentation and RF test setups.

Suitable for

• Antenna connections for radio transceivers and routers that use TNC interfaces
• Laboratory and field RF test equipment requiring 50 Ω cabling
• Signal extension between radio modules, repeaters and network devices
• Temporary or semi-permanent installations where a threaded connector improves mechanical stability

Key specifications

• Impedance: 50 Ω
• Connector type: TNC male to TNC female (threaded)
• Length: 10 m
• Primary use: RF signal transmission and antenna connection

How to use

Connect the TNC male end to the device with a TNC female socket and screw the TNC female end onto the equipment or antenna’s TNC male connector until hand-tight to ensure a secure connection. Avoid excessive torque when tightening to prevent damage to the connector. Route the cable to minimize sharp bends; maintain bend radii appropriate for coaxial cables to preserve impedance and reduce insertion loss. When installing in test setups or permanent runs, secure the cable with straps or clamps at intervals to prevent strain on the connectors.

Usage recommendations

Inspect connectors before use for debris or damage and replace the cable if the dielectric or shielding becomes compromised. For best RF performance, keep cable length as short as practical for the application and avoid running parallel to high-power AC lines to reduce interference.
