Coaxial RF Cable Rangeful HF400 TNC Male to SMA Male 50 Ω, 25 m

Rangeful HF400 TNC Male to SMA Male 50 Ω, 25 m is a coaxial RF cable designed for signal transmission between devices with TNC and SMA ports. The 25 metre HF400 cable provides a consistent 50 ohm impedance and is constructed to offer low insertion loss and dependable connector mating across longer cable runs. It is intended for use in antenna connections, test equipment setups and wireless systems that require a flexible yet stable RF link.

Advantages

This HF400 cable combines a robust coaxial structure with precision TNC male and SMA male terminations to ensure stable electrical contact and repeatable performance. Its 50 Ω characteristic impedance minimizes reflections when matching equipment specifications, while the larger diameter HF400 construction reduces signal attenuation over distance compared with thinner coax types. The flexible jacket facilitates routing in installations where longer runs are necessary without compromising shielding and mechanical durability.

Suitable for

• Connecting antennas to radio transceivers and base stations
• Linking test and measurement instruments with TNC or SMA ports
• Wireless system installations, including RF modules and repeaters
• Laboratory setups and prototyping where a 25 m cable length is required

Key specifications

• Connector configuration: TNC male to SMA male
• Impedance: 50 Ω
• Cable type: HF400 coaxial
• Length: 25 m
• Construction features: flexible jacket, braided shielding, foam or solid dielectric (typical HF400 structure)
• Use: RF signal transmission for frequencies typical of TNC/SMA systems

How to use

Ensure both devices to be connected are powered off before attaching the cable. Align the TNC male and SMA male connectors with their corresponding female ports and engage each connector by hand, tightening to a secure fit without excessive force. Route the 25 m cable to avoid sharp bends and kinks; maintain gentle bend radii consistent with HF400 cable handling to preserve impedance characteristics. After installation, power devices and verify signal levels and return loss as needed for the application.

Usage recommendations

For best performance, avoid repeated mechanical strain at the connector joints and keep the cable away from sources of strong electromagnetic interference. Periodically inspect connector interfaces for contamination or wear and replace the cable if the outer jacket or shielding is damaged. When used in critical measurement setups, verify cable loss and system calibration with a network analyzer or appropriate test equipment.
