Coaxial cable Rangeful HF240 1 m RP‑SMA male to N male 50 Ω

Rangeful HF240 is a 1 m coaxial cable terminating in an RP‑SMA male connector on one end and an N male connector on the other, with a characteristic impedance of 50 Ω. This cable is intended for short interconnections between RF devices, antennas and test equipment where standard 50 Ω impedance matching and a compact RP‑SMA to robust N connector transition are required.

Advantages

The construction provides consistent 50 Ω impedance along the 1 m length to minimise reflections and maintain signal integrity in RF applications. The RP‑SMA male connector offers a compact interface common on many wireless modules, while the N male connector provides a durable, weather-resistant connection suitable for outdoor or rack-mounted equipment. The cable’s length and connector combination make it convenient for short runs where space and connector compatibility are constraints.

Suitable for

• Connecting wireless modules or routers with RP‑SMA ports to external antennas with N‑type inputs
• Short RF test setups and laboratory interconnections between measurement instruments
• Indoor and sheltered outdoor antenna installations requiring 50 Ω matching
• Temporary or permanent links between RF components in communication systems

Key specifications

• Length: 1 m
• Connector A: RP‑SMA male
• Connector B: N male
• Impedance: 50 Ω
• Cable type: coaxial RF cable designed for signal transmission in radio frequency ranges

How to use

Ensure both devices are powered off before connecting to prevent damage from accidental RF or DC exposure. Align the RP‑SMA male connector with the corresponding RP‑SMA female socket and screw gently to engage the coupling threads without forcing; do not overtighten. Align the N male connector with the N female socket and hand‑tighten the coupling nut; use a calibrated torque wrench only if the installation specifies torque values. Verify secure mechanical connection and restore power to test signal transmission. For test and measurement scenarios, keep the cable as straight as practical to avoid unnecessary bends that can affect insertion loss.

Usage recommendations

For optimum performance, use this 50 Ω cable only within its intended RF frequency range and avoid sharp bends or repeated flexing near the connectors. When deployed outdoors, protect the RP‑SMA interface from moisture and use appropriate sealing at the N connector if exposed to weather. Replace the cable if the dielectric, braid or connectors show visible damage or if measured SWR degrades beyond acceptable limits.
