Coaxial cable Rangeful HF400-NM-NM-10, flexible LMR400/UF equivalent, 10 m, NM-to-NM connectors

Rangeful HF400-NM-NM-10 is a 10 m flexible coaxial cable equivalent to LMR400/UF, terminated with NM-to-NM connectors for direct connection between compatible radio equipment and antennas. Intended for RF signal transmission in amateur and professional radio setups, the cable provides lower signal loss than thinner coax types and a construction that balances flexibility and mechanical robustness for easier routing in indoor and protected outdoor installations.

Advantages

The cable combines a larger-diameter transmission line equivalent to LMR400/UF with flexible inner and outer jackets to simplify installation in confined spaces. Its design reduces insertion loss compared with smaller-diameter coax, improving signal strength over the 10 m run. NM-to-NM connectors are pre-fitted to eliminate the need for field termination and to ensure consistent electrical contact for typical antenna and radio interfaces that accept NM connectors.

Suitable for

• Feeding VHF/UHF antennas in amateur radio and hobbyist installations
• Connecting radio transceivers to external antennas in professional or semi-professional setups
• Indoor antenna runs and protected outdoor routing where flexible, low-loss coax is required
• Temporary or permanent installations that benefit from pre-terminated NM-to-NM connections

Key specifications

• Cable length: 10 m
• Construction: flexible coaxial design equivalent to LMR400/UF
• Connectors: NM-to-NM pre-fitted
• Application: RF signal transmission and antenna feedlines
• Installation environment: indoor and protected outdoor use

How to use

Route the 10 m coaxial cable between the radio equipment and the antenna, avoiding sharp bends and excessive tension. Connect the NM connectors to compatible NM-type sockets on the transceiver and antenna feedpoint, ensuring threaded interfaces are hand-tightened and secure. If passing the cable through walls or enclosures, use appropriate grommets or feed-through fittings to protect the cable jacket. For outdoor exposures, position the cable where it is protected from direct sunlight and mechanical abrasion, and secure it with suitable clamps or ties to prevent movement.

Usage recommendations

For optimal performance, keep bend radii greater than the cable's minimum recommended radius and avoid kinking. Check connector tightness periodically and ensure connectors remain dry and protected in outdoor or semi-exposed installations. Use compatible grounding practices for the antenna system as required by local regulations and equipment instructions.
