Coaxial cable Rangeful HF240 12m 50 Ohm with RP-SMA male to N male connectors

Rangeful HF240 is a 12 m, 50 Ω coaxial cable with an RP-SMA male connector at one end and an N male connector at the other. Engineered for RF signal transmission, the cable provides impedance matching across the connection between devices with different connector types. Its 12 metre length supports flexible placement of antennas and equipment while preserving signal integrity for amateur and professional radio, test benches, and outdoor installations where a longer feed line is needed.

Advantages

The cable offers consistent 50 Ω impedance to minimize reflections and maintain RF performance across the frequency range it is designed for. Fitted with an RP-SMA male connector and a rugged N male connector, the assembly provides reliable mechanical and electrical contact between consumer and professional radio equipment. The construction is intended for durability during repeated handling and routing over medium distances, enabling stable connections in test setups and deployed antenna systems.

Suitable for

• Connecting antennas to routers, modems or radios with differing connector types
• Laboratory and test bench RF measurements and temporary test rigs
• Amateur radio stations and field deployments requiring a longer feed cable
• Outdoor installations where a robust N male interface is required on one end

Key specifications

• Characteristic impedance: 50 Ω
• Cable length: 12 m
• Connector A: RP-SMA male
• Connector B: N male
• Application: RF signal transmission between devices with RP-SMA and N connectors
• Typical use: antenna feed line, test equipment interconnect

How to use

Inspect both connectors and mating ports for dirt or damage before installation. Securely hand-tighten the RP-SMA male connector to the corresponding RP-SMA female on the device, taking care not to cross-thread; then attach the N male connector to the N female port and tighten appropriately using a torque wrench or suitable spanner if specified by the equipment manufacturer. Route the cable to avoid sharp bends and excessive strain, and protect it from prolonged exposure to moisture or UV if used outdoors.

Usage recommendations

For reliable RF performance, maintain gentle bend radii and avoid kinking the cable. If the installation is permanent or exposed to weather, use additional sealing at the N connection and secure the cable with UV-resistant clips. When performing measurements, keep cable lengths as short as practical to reduce loss and verify connectors are fully seated to minimise return loss.
