Coaxial cable Rangeful HF240 TNC male to TNC male 7 m pure copper

Rangeful HF240 TNC male to TNC male 7 m pure copper is a coaxial cable designed for RF and antenna connections where reliable signal transmission and mechanical robustness are required. The 7-meter length provides medium-range connectivity while the pure copper conductor ensures low attenuation and stable performance in radio equipment, test benches and installations that use TNC connectors on both ends.

Advantages

The cable combines TNC male connectors on both ends with a pure copper conductor to deliver consistent impedance match and reduced signal loss compared with lower-quality conductors. Its length of 7 m offers flexibility in routing without the need for additional adapters. The construction provides mechanical durability and maintains signal integrity across a range of typical RF frequencies used in radio, testing and antenna systems.

Suitable for

• Connecting radio transceivers to external antennas
• Laboratory and bench test setups for RF measurements
• Linking signal generators or receivers with TNC interfaces
• Short to medium length installations in communication racks or enclosures

Key specifications

• Connector type: TNC male — both ends
• Cable length: 7 meters
• Conductor material: pure copper core
• Cable type: coaxial for RF applications
• Intended use: antenna and RF signal transmission over medium distances

How to use

Ensure both devices have compatible TNC female ports before connecting. Align each TNC male connector with the mating TNC female jack and rotate until the connector is securely threaded; avoid over-tightening to prevent damage to the connector or port. Route the 7 m cable to minimise sharp bends and avoid pinching; keep it away from high-power mains cables and strong electromagnetic sources to reduce interference. For test setups, connect the signal source and measurement device, then verify signal levels and impedance match with appropriate equipment.

Usage recommendations

For best performance, use the cable within its intended RF frequency range and avoid repeated harsh bending at the connector junctions. When installing permanently, secure the cable at intervals to prevent strain on connectors and periodically inspect connectors for corrosion or wear. Replace the cable if visible damage to the dielectric or conductor appears.
