Coaxial Cable Rangeful HF240 15m 50Ω — TNC Male to SMA Male

Rangeful HF240 is a 15-meter, 50 Ω coaxial cable terminated with a TNC male connector on one end and an SMA male connector on the other. It is designed to provide a fixed-length, low-loss RF link between equipment with TNC and SMA ports, delivering consistent impedance and physical durability for antenna feeds, test benches and signal routing in both field and laboratory environments.

Advantages

The cable offers a stable 50 ohm impedance across its length to minimize reflections and maintain signal integrity for radio frequency applications. Its 15 m fixed length reduces the need for intermediate adapters and minimizes potential points of failure. TNC and SMA male terminations provide secure mechanical connection and wide compatibility with common RF devices and adapters. The construction balances flexibility and robustness to allow for easy routing while resisting mechanical stress during regular use.

Suitable for

• Connecting antennas to transceivers in amateur and professional radio setups
• Laboratory test rigs and RF measurement chains
• Connecting signal generators, spectrum analyzers and other test instruments
• Temporary or permanent installations requiring a 50 Ω link over moderate distance

Key specifications

• Cable length: 15 meters
• Characteristic impedance: 50 Ω
• Connector types: TNC male to SMA male
• Typical use: RF signal transmission and antenna connection
• Construction: coaxial design with shielding to reduce interference

How to use

Connect the TNC male end to the device or antenna with a compatible TNC female port and the SMA male end to the device with an SMA female port. Ensure both connectors are clean and hand-tighten to avoid cross-threading; use a torque wrench where precise torque is required by instrumentation specifications. Route the cable to avoid sharp bends and heavy pinching; secure with non-abrasive ties or clamps at intervals to prevent strain on the connectors. For measurement setups, verify continuity and check return loss or VSWR with appropriate test equipment after installation.

Usage recommendations

Inspect connectors periodically for signs of wear or corrosion, and keep contact surfaces free of dirt. Avoid exceeding the recommended bending radius of the coaxial cable and minimize exposure to extreme temperatures and chemicals. When long-term outdoor use is intended, consider additional environmental protection or conduit to extend service life.
