Coaxial cable Rangeful HF400 50 Ohm, TNC male to SMA male, full copper, 1 m

Rangeful HF400 is a 1 m, 50 Ohm coaxial cable fitted with a TNC male connector on one end and an SMA male connector on the other. The cable features full copper conductors and shielding designed for short RF and antenna links where reliable signal transmission and low insertion loss are required. Its compact length and common connector pair make it suitable for connecting test equipment, radio modules, routers and other devices that use standard 50 Ω coax interfaces.

Advantages

The full copper construction ensures good conductivity and consistent impedance along the cable, helping to minimise signal attenuation and reflections. The TNC male to SMA male connector configuration provides mechanical stability and straightforward mating with many RF devices and adapters. At 1 m length the cable offers flexible routing in test benches and installations while keeping losses low compared with longer leads.

Suitable for

• Connecting RF test equipment and measurement instruments
• Linking antennas to routers, modems and radio transceivers
• Laboratory setups and short-range cable runs
• Interfacing modules with TNC or SMA 50 Ω ports

Key specifications

• Characteristic impedance: 50 Ohm
• Cable length: 1 m
• Inner conductor and shielding material: full copper
• Connector A: TNC male
• Connector B: SMA male
• Typical application: RF and antenna connections

How to use

Connect the TNC male end to the corresponding TNC female port and the SMA male end to an SMA female port, ensuring both connectors are clean and free from debris before mating. Hand-tighten the threaded SMA and TNC connections until secure; avoid excessive force to prevent damage to connector threads. Route the cable to avoid sharp bends and high-stress points; maintain bend radii appropriate for coaxial cable to preserve impedance characteristics.

Usage recommendations

For best performance, keep cable runs as short as practical and avoid routing near strong sources of electromagnetic interference. Inspect connectors before each use and replace the cable if you observe damaged plating, exposed conductor, or compromised shielding. Use compatible 50 Ω equipment and adapters to maintain correct impedance and minimise return loss.
