Coaxial cable Rangeful HF240-RPSM-NM-3 3 m 50 Ω RP-SMA male → N male

Coaxial cable Rangeful HF240-RPSM-NM-3 is a 3-meter, 50 Ω RF cable with an RP-SMA male connector at one end and an N male connector at the other. It is designed for reliable RF signal transmission between devices with RP-SMA and N-type ports, providing a balance of flexibility and low loss for indoor and controlled outdoor setups. The cable is suitable for use with routers, antennas, test equipment and wireless systems where a 50 Ω connection is required.

Advantages

The 50 Ω impedance ensures compatibility with standard RF equipment, minimizing reflections and maintaining signal integrity. The RP-SMA male to N male termination allows direct connection between common consumer and professional radio-frequency devices without additional adapters. At 3 meters length the cable offers convenient reach for many installations while keeping insertion loss moderate. Construction materials and connector plating are selected to provide stable electrical contact and resistance to routine handling.

Suitable for

• Connecting routers or access points with RP-SMA ports to N-type antennas
• Extending antenna feeds for wireless links and repeaters
• Laboratory and field testing where RP-SMA to N interfaces are required
• Integration with RF equipment such as signal generators, spectrum analyzers and receivers

Key specifications

• Impedance: 50 Ω
• Length: 3 m
• Connector A: RP-SMA male (reverse polarity SMA male)
• Connector B: N male
• Cable type: coaxial for RF applications
• Typical use: low-loss signal transmission in RF systems

How to use

Connect the RP-SMA male end to the device or antenna with an RP-SMA female port, and connect the N male end to the device or antenna with an N-type female port. Ensure connectors are properly aligned and hand-tighten where applicable; avoid excessive torque which can damage connector threads or affect performance. Route the cable to avoid sharp bends and compression; maintain a bend radius appropriate for coaxial cables to prevent increased loss or mechanical damage.

Usage recommendations

For best performance, use this 50 Ω cable in installations matching system impedance and keep cable length as short as practical for the application. Inspect connectors for dirt or corrosion before mating and avoid repeated mating cycles beyond normal use. When used outdoors, protect connector interfaces from moisture with suitable weatherproofing, and avoid exposing the cable to prolonged direct sunlight or mechanical abrasion.
