Coaxial cable Rangeful HF400-NM-NM-5, 5 m, flexible, LMR400/UF equivalent, NM-NM connectors

Rangeful HF400-NM-NM-5 is a 5 m flexible coaxial cable fitted with NM (UHF) male connectors at both ends and specified as equivalent to LMR400/UF. It is designed for RF signal transmission where a thicker 400-series coax is required to reduce loss and preserve signal integrity over short to medium cable runs. The cable’s flexible jacket allows easier routing in confined spaces and across indoor or outdoor installations while maintaining the electrical characteristics expected from higher-performance coax.

Advantages

The cable combines a larger-diameter RF inner conductor and dielectric consistent with 400-series performance, providing lower attenuation compared with thinner coax types over the same distance. Factory-attached NM (UHF) male connectors at both ends eliminate the need for separate termination tools and provide a secure threaded connection to compatible devices. Flexibility of the outer jacket simplifies installation around bends and through conduits and helps reduce mechanical stress at connector junctions.

Suitable for

• Antenna connections for radios, base stations and scanning equipment
• Radio equipment linking where low-loss 400-series cable is preferred
• Test and measurement setups requiring stable RF feedlines
• Indoor and outdoor cable runs where flexibility and easy routing are needed

Key specifications

• Cable length: 5 m
• Connector type: NM (UHF) male to NM (UHF) male
• Construction: flexible jacket; 400-series equivalent (LMR400/UF equivalent)
• Application: RF signal transmission for antennas and radio equipment

How to use

Connect each NM (UHF) male connector to the corresponding female UHF (SO-239) or compatible socket on your antenna, transceiver or test instrument. Ensure threads are engaged and hand-tighten to provide a stable mechanical connection; avoid over-tightening with tools to prevent damage to connector threads. Route the cable to avoid sharp bends and kinks; maintain gentle bend radii consistent with the cable’s flexibility to preserve electrical performance.

Usage recommendations

For optimal performance, use this 5 m HF400 cable where reduced loss is required over shorter runs compared with thinner coax. Avoid exposing connector junctions to prolonged moisture without additional sealing; for outdoor installations consider weatherproofing the connector interface. When installing through conduit or tight spaces, confirm bend radius and avoid crushing the cable to maintain impedance characteristics.
