Coaxial cable Rangeful HF240-RPSM-NMH-2 2 m 50 Ω RP-SMA male to N male

Rangeful HF240-RPSM-NMH-2 is a 2 m coaxial cable with nominal 50 Ω impedance, fitted with an RP‑SMA male connector at one end and an N male connector at the other. The cable is designed for RF signal transmission between equipment with RP‑SMA and N interfaces and is suitable for extending or adapting antenna and radio links where a 50 Ω feed is required. The construction provides a straightforward, mechanically secure connection for routers, external antennas, radios and measurement instruments.

Advantages

The cable combines common RF connector types on a flexible 2 metre lead, enabling easy adaptation between RP‑SMA and N ports without the need for additional adapters. Its 50 Ω characteristic impedance maintains signal integrity for a wide range of wireless and RF applications. The robust connectors and shielding reduce signal loss and provide stable mechanical mating for repeated connections.

Suitable for

• Connecting external antennas to routers, access points and gateways with RP‑SMA or N ports
• Linking radios, transceivers or test equipment that require 50 Ω cabling
• Extending or adapting RF feedlines in lab, field or installation environments
• Temporary setups for signal testing and measurement

Key specifications

• Cable length: 2 m
• Characteristic impedance: 50 Ω
• Connector A: RP‑SMA male
• Connector B: N male
• Intended use: RF signal transmission between RP‑SMA and N interfaces

How to use

Identify the RP‑SMA and N ports on the devices to be connected. Align the RP‑SMA male connector with the RP‑SMA female socket and engage until hand-tight; avoid overtightening. Connect the N male connector to the corresponding N female jack and tighten appropriately, using a torque wrench if specified by the equipment manufacturer. Route the cable to minimise sharp bends and avoid placing it near strong sources of interference or mechanical wear. Verify the connection by testing signal levels or device communication after installation.

Usage recommendations

For best RF performance, keep cable runs as short as practical, avoid tight bends and secure the cable to prevent strain on the connectors. When used in measurement setups, allow adequate connector torque and inspect connectors for cleanliness to reduce insertion loss. Replace the cable if the outer sheath or connector mating surfaces show visible damage.
