## Summary description

Rangeful HF400 coaxial cable with TNC male to SMA male connectors, 3 meters long. Built on full-copper HF400 coaxial with 50 ohm impedance for reliable RF signal transmission. Suitable for connecting antennas, radio equipment, test instruments and wireless devices where TNC and SMA interfaces are required. Flexible length supports installation and testing with low loss.

## Long description

Rangeful HF400 TNC male to SMA male coaxial cable, 50 Ω, 3 m, is designed for reliable RF signal transmission between devices using TNC and SMA connectors. Built on a full-copper HF400 coaxial core with 50-ohm characteristic impedance, this cable provides a consistent conductive path for antennas, radio equipment, test instruments and wireless devices. The 3-meter length allows flexible placement and temporary or semi-permanent installations while maintaining low-loss performance appropriate for many RF applications.
Advantages
The cable uses full-copper conductors and HF400 coaxial construction to ensure stable electrical characteristics and improved conductivity. Gold-plated TNC male and SMA male connectors provide secure mechanical mating and corrosion resistance for consistent signal transfer. A 50 Ω impedance match reduces reflections when connected to compatible RF equipment. The 3 m length balances reach and signal integrity for installations and bench testing where modest cable runs are required.
Подходит для
Подключения антенн к радиоприёмному и передающему оборудованию
Соединения измерительных приборов и тестовых стендов с RF-разъёмами TNC и SMA
Интеграции беспроводных устройств и модулей в прототипы и промышленные системы
Временных или стационарных монтажей, где требуется кабель длинной 3 м и 50 Ω
Key specifications
Connector A: TNC male
Connector B: SMA male
Impedance: 50 Ω
Cable type: HF400 full-copper coaxial
Length: 3 m
Conductor material: copper
How to use
Connect the TNC male end to the device with a compatible TNC female socket and the SMA male end to the device with an SMA female socket, ensuring threaded connectors are hand-tightened to maintain a secure connection. Route the cable to avoid sharp bends and excessive mechanical stress; maintain bend radii recommended by the equipment manufacturer to prevent degradation of RF performance. For test and measurement use, keep cable runs as short as practical and avoid close parallel routing with power lines to reduce interference.
Usage recommendations
Store the cable coiled without kinks and protect connector ends with caps when not in use. Inspect connectors periodically for contamination or damage and replace the cable if you observe significant wear that could affect impedance or introduce signal loss.
