Coaxial cable Rangeful HF400-NM-NM-2 2 m — flexible LMR400/UF equivalent, NM to NM connectors

Rangeful HF400-NM-NM-2 is a 2 m coaxial cable with NM (female) to NM (female) connectors, manufactured as a flexible equivalent to LMR400/UF-type low-loss RF cable. It is intended for RF and antenna installations where a short, flexible feedline with robust connector interfaces is required. The cable assembly provides a balance of mechanical flexibility and electrical performance suitable for indoor and sheltered outdoor use in radio, amateur, and commercial antenna systems.

Advantages

The cable offers low insertion loss typical of LMR400-equivalent constructions while maintaining improved flexibility compared with larger semi-rigid coax. Both ends are fitted with NM (female) connectors for straightforward mating with equipment using NM interfaces. The 2 m length reduces the need for adapters or additional junctions in short-run installations, and the cable jacket and shielding provide consistent RF performance with reduced interference and signal leakage.

Suitable for

• Connecting antennas to radios, transceivers and repeaters over short distances
• Indoor and sheltered outdoor RF feedline runs where flexibility is needed
• Amateur radio setups, base station patching and test bench connections
• Temporary installations and field testing where a durable, low-loss cable is required

Key specifications

• Cable type: flexible LMR400/UF equivalent coaxial construction
• Length: 2 meters
• Connector configuration: NM (female) to NM (female)
• Electrical performance: designed for low insertion loss typical of LMR400-class cable
• Mechanical: flexible jacket suitable for routing in confined spaces

How to use

Ensure both mating connectors on the intended equipment are NM (female) compatible or use appropriate adapters if required. Route the cable to avoid sharp bends and mechanical strain on the connector ends; maintain a bend radius consistent with flexible LMR400-type coax to preserve electrical performance. Connect one end to the antenna or feedpoint and the other to the radio, repeater or measurement device, then hand-tighten the NM connectors to ensure a secure RF joint. For outdoor use, place connections in a weather-protected enclosure or apply suitable sealing methods to prevent moisture ingress at the connector interfaces.

Usage recommendations

For best RF performance, minimize unnecessary length and avoid running the cable parallel to power lines or sources of electromagnetic interference. Periodically inspect connectors for corrosion or loose fittings and replace the cable if the jacket is damaged or shielding integrity appears compromised.
