Coaxial cable Rangeful HF240 1 m, 50 Ω, TNC male to SMA male

Rangeful HF240 is a 1 m coaxial jumper cable with TNC male to SMA male connectors and a 50 Ω characteristic impedance. It is built for RF and antenna connections where a compact, reliable link between TNC and SMA interfaces is required. The cable is suitable for test benches, radio equipment, routers, antennas and other RF systems that require a standard 50-ohm connection and low insertion loss over short distances.

Advantages

The cable provides a straightforward connection between TNC and SMA male interfaces without the need for adapters, reducing connection points and potential signal loss. With a defined 50 Ω impedance it maintains impedance matching across the link for consistent signal transfer. Its 1 m length balances flexibility and manageability in bench and field setups, and the common connector types ensure compatibility with a wide range of RF devices and antenna systems.

Suitable for

• Connecting radio transceivers and antennas
• Linking routers or gateways with TNC to devices with SMA
• Laboratory test setups and measurement equipment
• Temporary or permanent installations requiring a short RF jumper

Key specifications

• Cable length: 1 meter
• Characteristic impedance: 50 Ω
• Connector type (ends): TNC male to SMA male
• Application: RF/antenna connections and signal transmission

How to use

Inspect connectors and device ports for cleanliness and damage before connecting. Align the TNC male and SMA male connectors with their respective female ports and hand-tighten the threaded couplings to ensure a secure mechanical and electrical connection; avoid over-tightening. Route the cable to minimize sharp bends and stress at the connector junctions. For measurement or temporary setups, place the cable in a position that reduces movement to maintain stable readings.

Usage recommendations

Use this 1 m TNC male to SMA male cable in line with standard RF handling practices: keep connectors capped when not in use, avoid kinking the cable, and perform periodic visual inspections. For critical RF paths, confirm insertion loss and VSWR meet system requirements at the operating frequency range and replace the jumper if mechanical wear or connector degradation is observed.
