## Summary description

This Rangeful HF400 coaxial cable features a TNC male connector on one end and an SMA male connector on the other, 20 meters long and 50 Ω impedance. The flexible HF400 construction is suitable for RF signal transmission, antenna connections, test setups and repeater links where moderate loss and flexibility are required. Provides reliable mechanical connections and consistent impedance for cellular, radio and wireless equipment.

## Long description

This Rangeful HF400 coaxial cable features a TNC male connector on one end and an SMA male connector on the other, with a length of 20 meters and a characteristic impedance of 50 Ω. The cable uses a flexible HF400 construction designed for RF signal transmission, offering a balance between flexibility and controlled loss. It is intended for reliable mechanical connections and consistent impedance when linking cellular, radio and wireless equipment, antennas, repeaters and test instruments.
Advantages
The cable combines an HF400 flexible dielectric and shielding structure with precision TNC male and SMA male terminations to maintain a stable 50 Ω transmission path. Its 20 m length allows extended reach without multiple adapters. The flexible construction reduces stress at connector interfaces and facilitates routing in confined or curved installations. Connectors provide secure mechanical mating suitable for frequent assembly and disassembly in test or field environments.
Suitable for
 Connecting antennas to radio equipment and repeaters
 RF test setups between instruments with TNC and SMA interfaces
 Temporary or semi-permanent installations requiring flexible routing
 Cellular and wireless equipment linking where 50 Ω impedance is required
Key specifications
 Connector A: TNC male
 Connector B: SMA male
 Length: 20 m
 Characteristic impedance: 50 Ω
 Cable type: HF400 flexible coaxial construction
 Application: RF signal transmission, antenna and test connections
How to use
Ensure both mating connectors (TNC and SMA) on the connected devices are clean and undamaged before attaching the cable. Hand-tighten the SMA and TNC connectors to avoid over-torquing; use a calibrated torque wrench only if specified by the equipment manufacturer. Route the cable with gentle bends that respect the cable’s minimum bend radius to avoid kinking and to maintain consistent RF performance. Avoid sharp edges and mechanical strain at connector junctions; secure the cable with appropriate clamps or ties on long runs.
Usage recommendations
 For best performance, use the cable in environments within the intended operating temperature and humidity ranges of your equipment, avoid exposure to excessive moisture or corrosive substances, and inspect connectors periodically for wear. When used in test setups, keep cable length as short as practical to reduce insertion loss and verify system performance after installation.
