Coaxial Cable Rangeful HF400-BNCM-BNCM-40 — BNC Male to N Male, 40 m, LMR400 UF / UltraFlex equivalent

Rangeful HF400-BNCM-BNCM-40 is a 40 m flexible coaxial cable with a BNC male connector on one end and an N male connector on the other. Constructed as an LMR400 UF / UltraFlex equivalent, this cable is designed for RF signal transmission with low loss and improved flexibility compared with standard rigid coax. It is intended for antenna installations, base stations, test setups and professional radio or CCTV systems that require LMR400-class performance over a long, flexible run.

Advantages

The cable provides a balance of low attenuation and mechanical flexibility, making it suitable for runs where movement or tight routing is expected. Its combination of BNC male and N male connectors allows direct connections between BNC-equipped devices and N-type antenna or RF equipment without additional adapters. Being an LMR400 UF / UltraFlex equivalent, it offers electrical characteristics similar to LMR400 while remaining easier to bend and install in confined spaces.

Suitable for

• Antenna feedlines for outdoor or indoor installations
• Connecting radio transceivers or base station equipment to antennas
• Professional CCTV systems that use RF video over coax
• Laboratory and test setups requiring repeatable RF connections over 40 m

When it may not be suitable

This cable is designed for applications that require LMR400-class performance and flexibility; it may not be appropriate where heavier spec low-loss cables (for example, true hard-dielectric or larger-diameter coax such as full 7/8") are required for minimal attenuation over very long distances. It is also not suitable where both ends require identical connector types other than BNC male to N male without adapters.

Key specifications

• Cable length: 40 m
• Connector types: BNC male (one end), N male (other end)
• Cable type: LMR400 UF / UltraFlex equivalent coaxial
• Intended use: RF signal transmission for antennas, base stations, CCTV and test equipment
• Characteristic impedance: 50 Ω

How to use

Route the 40 m coaxial cable between the RF source and the antenna or device, avoiding sharp bends and tight kinks; maintain bend radii recommended for LMR400-class cables to preserve electrical performance. Connect the BNC male to the corresponding BNC jack and the N male to the N-type jack, ensuring threads on the N connector are hand-tightened and, if required, secured with a torque wrench to manufacturer torque specifications for N-type. For outdoor installations, use appropriate weatherproofing on the N connector and any exposed BNC connections to prevent moisture ingress and corrosion.

What to consider before purchase

• Verify that BNC male and N male connectors match your equipment ports without needing adapters
• Confirm that 40 m cable length and LMR400-class attenuation meet your link budget and signal loss requirements
• Check routing constraints and whether the cable's flexibility is sufficient for installation paths
• Plan for outdoor sealing or additional protective conduit if the cable will be exposed to weather

Usage recommendations

For best RF performance, keep cable runs as short as practical, avoid sharp bends, use proper connector torque on N-type joints, and apply suitable weatherproofing for any outdoor connectors. Test signal levels after installation to confirm losses are within acceptable limits for the application.
