Coaxial cable Rangeful HF400 TNC male to SMA male 50 Ω, 15 m

Rangeful HF400 coaxial cable with TNC male to SMA male connectors is a 15 m, 50 Ω interconnect designed for RF signal transmission between devices with TNC and SMA ports. The cable provides a flexible routing option for longer runs while maintaining the characteristic 50-ohm impedance required for many radio, test and antenna applications. Intended for use where reliable connectivity and minimal impedance mismatch are needed, this cable connects transceivers, test instruments, antennas and other RF equipment that accept TNC or SMA male interfaces.

Advantages

This Rangeful HF400 cable offers consistent 50 Ω impedance across its length, reducing reflections and preserving signal integrity in RF paths. The TNC male and SMA male connectors provide mechanically secure threaded connections for stable mating. The 15 m length enables flexible placement of equipment and antennas without resorting to multiple adapters or shorter patch cables. The cable construction balances flexibility and durability to allow routing in typical indoor and sheltered outdoor installations.

Suitable for

• Test setups and laboratory equipment interconnections
• Connecting antennas to radio transceivers and receivers
• Amateur radio stations and field operations
• Temporary or semi-permanent RF installations requiring 15 m runs

Key specifications

• Impedance: 50 Ω
• Length: 15 m
• Connector A: TNC male
• Connector B: SMA male
• Cable type: HF400 coaxial

How to use

Verify that both connected devices accept TNC male and SMA male terminations or use appropriate adapters where necessary. Route the cable to avoid sharp bends and excessive compression; reasonable bend radius preserves electrical performance. Thread the TNC and SMA connectors by hand until they are fully seated and finger-tight; avoid over-torquing threaded connections. After installation, check for expected RF performance with a power meter, SWR meter or antenna analyzer as applicable to the equipment in use.

Usage recommendations

For best results, avoid prolonged exposure to direct weather and UV unless the cable is installed in a protected conduit or weatherproofed; inspect connectors periodically for corrosion or loosening. Use the 15 m length to minimize the number of connections and adapters in the signal path, and select the shortest practical route that maintains the required bend radius to preserve impedance and minimize loss.
