Coaxial Cable Rangeful BNC Male to N Male 25m — LMR400 UF / UltraFlex equivalent

Rangeful BNC Male to N Male 25m flexible coaxial cable is a high-flex performance RF lead designed for antenna and test connections. Specified as an LMR400 UF / UltraFlex equivalent, this 25-metre assembly combines low insertion loss with repeated flex resistance, making it suitable for installations where a robust, flexible feedline is needed between transceivers, base stations and antennas.

Advantages

This coaxial cable offers a balance of low attenuation and mechanical flexibility. Its LMR400 UF / UltraFlex-equivalent construction provides consistent characteristic impedance and shielding effectiveness while allowing tighter bends and movement than standard solid-jacket LMR400. Pre-fitted BNC male and N male connectors enable quick mating with common amateur radio transceivers, test instruments and antenna systems, reducing installation time and handling stress on connector joints.

Suitable for

• Amateur radio transceiver to antenna feedlines
• Base station and fixed station RF connections
• Test bench connections between signal generators, spectrum analysers and DUTs
• Semi-mobile installations where cable routing requires repeated bending

When it may not be suitable

This cable is specified as an UltraFlex-equivalent and provides improved flexibility compared with standard LMR400, but it is still larger and less flexible than smaller-diameter coax types. It may not be the best choice for tight-space routing inside very compact enclosures or where the absolute minimum weight and diameter are required.

Key specifications

• Cable length: 25 metres
• Connector type: BNC male on one end, N male on the other
• Cable category: LMR400 UF / UltraFlex equivalent construction
• Characteristic impedance: 50 ohm
• Application: RF, antenna feedline, test connections

How to use

Route the cable between the radio or test instrument and the antenna or measurement device taking care to avoid sharp kinks. Connect the BNC male connector to the corresponding BNC female jack on your equipment and secure the N male connector to the N female on the antenna or feedthrough by hand-turning the coupling nut until firm; use a properly sized torque wrench only if specified by the connected equipment to avoid over-tightening. Maintain gentle bend radii near connectors and secure the cable along its run to prevent movement and strain during operation.

What to consider before purchase

• Ensure 50 ohm compatibility with your equipment and antennas
• Confirm that BNC male and N male terminations match your connection points
• Consider run length and height to evaluate RF loss for your operating frequencies
• Check required bend radius and routing space for a 25 m length and LMR400-diameter cable

Usage recommendations

For best performance, keep cable runs as short as practical, avoid tight bends and secure the cable to prevent movement. Periodically inspect connectors for corrosion or loose fittings, especially in outdoor installations, and use appropriate weatherproofing on exposed connections.
