Coaxial cable Rangeful HF240 TNC male–TNC male 50 Ω, 0.5 m

Rangeful HF240 is a 0.5 m coaxial cable fitted with TNC male connectors on both ends and a characteristic impedance of 50 Ω. It is designed for RF and microwave signal transmission where a short, reliable connection between TNC-equipped devices is required. The cable provides a compact link suitable for antenna feeds, measurement equipment and radio communications hardware that use TNC interfaces.

Advantages

The cable offers low-reflection 50 Ω matching and stable performance across typical RF frequency ranges for TNC-terminated assemblies. Its short 0.5 m length reduces insertion loss and minimizes signal degradation in bench-top setups or equipment racks. TNC male connectors ensure secure threaded coupling for mechanical stability and predictable electrical contact.

Suitable for

• Connecting antennas to transceivers or tuners
• Linking RF test instruments and measurement fixtures
• Interconnecting radio devices, modems and base stations with TNC ports
• Short patch leads within equipment racks or laboratory benches

Key specifications

• Connector type: TNC male — TNC male
• Impedance: 50 ohm
• Length: 0.5 m
• Cable type: coaxial designed for RF/microwave signals
• Coupling: threaded TNC for secure mechanical connection

How to use

Prior to connection, ensure both mating TNC female ports are free of debris and properly aligned. Thread the TNC male coupling nut clockwise until hand-tight; avoid excessive force to prevent damage to the connector assembly. Use the cable to bridge equipment with matching 50 Ω TNC interfaces, keeping the run short and without sharp bends to maintain consistent RF performance. For test setups, route the cable to minimize coupling with other signal lines and avoid kinks.

Usage recommendations

For optimal signal integrity, use the Rangeful HF240 for short interconnects where 50 Ω matching is required. Avoid repeated high-torque tightening and protect the connectors from moisture and particulate contamination. When used with sensitive measurement equipment, allow connectors to seat fully and check for stable readings after installation.
