Coaxial cable Rangeful HF240 0.3 m RP-SMA male to N male 50 Ohm

Coaxial cable Rangeful HF240 0.3 m RP-SMA male to N male 50 Ohm is a short RF interconnect designed for 50 Ω systems. The cable joins devices with RP-SMA and N male interfaces, providing a compact, low-loss connection suitable for installations where space is limited or where a short jumper is required between antenna ports, routers, radios and test instruments. The HF240 construction focuses on consistent impedance and reliable mating of RP-SMA and N connectors to maintain signal integrity across the link.

Advantages

The 0.3 m length reduces signal attenuation compared with longer leads and helps keep cable management tidy in racks and dense installations. The combination of RP-SMA male and N male connectors provides compatibility between consumer and professional RF equipment without additional adapters. Built to 50 Ohm specification, the cable supports a broad range of RF frequencies used in wireless networking, telemetry and measurement setups while minimizing reflections and losses when properly matched.

Suitable for

• Connecting routers, modems or access points to external antennas
• Linking test equipment and RF measurement devices to antennas or converters
• Short interconnects in equipment racks and laboratory benches
• Temporary or permanent connections in radio and telemetry systems

Key specifications

• Cable length: 0.3 m
• Characteristic impedance: 50 Ω
• Connector A: RP-SMA male
• Connector B: N male
• Low-loss coax construction suitable for RF use

How to use

Align the RP-SMA male connector with the device's RP-SMA female socket and screw the mating nut by hand until snug; avoid over-tightening to prevent damage to the connector threads. Align the N male connector with the corresponding N female jack and tighten using an appropriate wrench to the torque recommended by the device manufacturer, ensuring a secure, low-resistance connection. Route the cable to avoid sharp bends and close proximity to high-voltage or noisy power sources to preserve signal quality.

Usage recommendations

For best performance, use this 0.3 m cable when a short, direct RF link is needed and when both devices specify 50 Ω impedance. Inspect connector mating surfaces for dirt or damage before use. Avoid repeated flexing near the connector ends to maintain mechanical and electrical integrity over time.
