Coaxial Cable Rangeful HF400 12m — TNC Male to SMA Male, Full Copper, 50 Ohm

Rangeful HF400 12m coaxial cable with TNC male to SMA male connectors is a 50 Ohm full-copper assembly engineered for radio frequency signal transmission. The 12 metre length provides extended reach for antenna connections, radio equipment linking and test setups. Constructed with full copper conductors and standard HF400 dielectric and shielding geometry, this cable is intended to offer consistent impedance and low insertion loss where reliable RF connections are required.

Advantages

The cable features full-copper conductors that improve conductivity and maintain signal integrity over a longer run compared with plated alternatives. TNC male and SMA male connectors provide secure threaded mating suitable for devices and test equipment that require robust mechanical connection. The 50 Ohm nominal impedance matches common RF systems and helps minimise return loss in antenna and radio-frequency signal paths.

Suitable for

• Connecting antennas to radio transceivers and scanners
• Linking routers, modems or RF front-ends with SMA or TNC ports
• Lab measurements and test setups requiring stable 50 Ohm connections
• Amateur radio installations and portable field setups

Key specifications

• Length: 12 metres
• Characteristic impedance: 50 Ohm
• Connectors: TNC male to SMA male
• Conductor material: full copper
• Cable type: HF400-class coaxial

How to use

Inspect connector threads and mating ports for debris or damage before installation. Hand-tighten the TNC and SMA connectors until a snug, threaded engagement is achieved; avoid over-torquing to prevent damage to connector bodies or equipment ports. Route the cable to minimise sharp bends and avoid kinks; maintain bend radii appropriate for HF400 coaxial assemblies to reduce impedance discontinuities. For temporary test setups, secure the cable to prevent strain on connectors.

Usage recommendations

Use the cable in environments within typical indoor or sheltered outdoor conditions and avoid prolonged exposure to moisture or direct sunlight without additional protection. When used for measurement or calibration tasks, allow connectors to be clean and ensure consistent mating to preserve measurement accuracy. If long-term outdoor routing is required, consider additional weatherproofing at connector interfaces.
