Coaxial cable Rangeful HF240 SMA male to RP-TNC male, 7 m length

Rangeful HF240 coaxial cable with SMA male to RP‑TNC male connectors, 7 m length, provides a flexible RF link for connecting devices with SMA and reverse‑polarity TNC interfaces. The cable is made for general-purpose RF signal transmission, offering standard coaxial shielding and factory‑mounted connector terminations to ensure consistent electrical contact and simple plug‑and‑play installation in test benches, antenna systems, and wireless equipment setups.

Advantages

The cable combines a commonly used SMA male connector with an RP‑TNC male terminator to bridge equipment featuring different RF interfaces without adapter stacks. Its 7 m length gives extended reach while maintaining flexibility for routing in racks or along walls. Standard coax shielding reduces external interference and preserves signal integrity over the run, and the connectorized ends reduce the risk of poor field terminations compared with bare‑ended cable.

Suitable for

• Connecting antennas to routers, modems or radio modules that use SMA and RP‑TNC interfaces
• Laboratory and field testing of wireless equipment requiring a 7 m RF link
• Temporary or semi‑permanent installations where a flexible, connectorized coax cable is needed
• Signal routing in communication racks, base station feeders, and IoT gateway setups

Key specifications

• Cable type: HF240 coaxial
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse‑polarity TNC)
• Length: 7 meters
• Shielding: standard braided/coaxial shielding
• Construction: factory‑assembled connector terminations
• Typical use: RF signal transmission for UHF/VHF/Wi‑Fi frequencies (dependent on device specifications)
• Flexibility: moderate, suitable for routing in equipment rooms and along cable trays

How to use

Inspect both connectors and device ports for debris before connection. Align the SMA male and RP‑TNC male connectors correctly and engage by hand; do not force connections. Tighten SMA and TNC interfaces by hand until snug—if a torque wrench is available, use the manufacturer‑recommended torque for SMA connectors to avoid damage. Route the 7 m cable to avoid sharp bends or kinks and secure it with soft ties or clips to prevent strain on connector terminations. For testing, connect the cable between the signal source and receiver or measurement instrument and verify continuity and return loss with appropriate RF test equipment if required.

Usage recommendations

Store the cable coiled loosely to prevent permanent deformation and avoid repeated tight bending near the connectors. When installing in outdoor or harsh environments, add additional weatherproofing at the connector interfaces and protect against moisture and mechanical strain. Replace the cable if connectors show corrosion, excessive wear, or if electrical performance degrades.
