Coaxial cable Rangeful HF240 SMA Male to RP-TNC Male 5 m

Coaxial cable Rangeful HF240 SMA Male to RP-TNC Male 5 m is a flexible RF lead designed to connect devices with SMA and RP-TNC ports. The 5 metre length provides additional reach for antenna placement, routers, modems and test equipment while preserving signal continuity for low- to mid-frequency RF applications. The cable assembly combines an SMA male connector on one end and an RP-TNC male connector on the other, enabling compatibility between equipment that use these common RF interfaces.

Advantages

The HF240 construction offers a balance of flexibility and shielding suitable for installations where cable routing and movement are required. The SMA male to RP-TNC male termination ensures correct mechanical fit and reliable electrical contact with corresponding ports. A 5 m cable length reduces the need for extensions or temporary configurations during setup and testing, and the cable maintains consistent impedance for predictable RF performance in its intended frequency range.

Suitable for

• Connecting external antennas to routers and modems with SMA or RP-TNC interfaces
• Linking RF test equipment and measurement instruments for signal routing
• Temporary or permanent installations where a 5 m flexible lead is required
• Prototyping and lab setups that require interconnection between devices with different connector types

Key specifications

• Cable type: HF240 coaxial
• Connector A: SMA male
• Connector B: RP-TNC male (reverse polarity TNC male)
• Length: 5 metres
• Impedance: 50 ohm nominal
• Typical applications: low- to mid-frequency RF signal transmission
• Cable flexibility: designed for easy routing and positioning

How to use

Inspect both connectors and mating ports for debris or damage before connecting. Align the SMA male with the SMA-style receptacle and engage by hand to avoid cross-threading; do not overtighten. For the RP-TNC male, align the reverse-polarity TNC interface and secure by hand until firmly seated. Route the cable to avoid sharp bends, kinks or close contact with sources of strong electromagnetic interference. When used with active equipment, connect the cable while devices are powered down if possible to prevent transients; power up and verify signal continuity in the system after installation.

Usage recommendations

For reliable RF performance, avoid repeated flexing at the connector junctions, maintain gentle bend radii consistent with HF240 cable characteristics, and store the cable coiled loosely when not in use. Use torque-limiting tools only if specified by the equipment manufacturer, and inspect connections periodically in critical installations.
