Coaxial cable Rangeful HF400-RPTNCM-NM-25 N male to RP-TNC male, 25 m, UltraFlex

Coaxial cable Rangeful HF400-RPTNCM-NM-25 N male to RP-TNC male, 25 m, UltraFlex is a 25‑meter RF interconnect designed for flexible, low-loss transmission between devices with N male and RP‑TNC male interfaces. The UltraFlex construction provides easier routing in confined or complex installations while maintaining the electrical characteristics required for antenna, radio, repeater and test bench connections. The cable is intended for use where a dependable, long cable run and compatible connectors are required for outdoor or indoor RF systems.

Advantages

The UltraFlex dielectric and braid construction reduce bending stiffness, enabling tighter radii and simpler deployment without significantly affecting signal integrity. The combination of a standard N male connector and an RP‑TNC male connector ensures compatibility between common base stations, antennas, transceivers and test equipment. The 25 m length offers extended reach for field installations, testing setups or equipment racks where direct proximity is not available.

Suitable for

• Connecting antennas to radios or repeaters where one side requires N male and the other requires RP‑TNC male
• Temporary or permanent field installations that need a flexible long cable run
• Laboratory or test bench setups for RF measurements and device interoperability checks
• Mobile communication setups and base station extensions with mixed connector types

Key specifications

• Cable type: RG/ultra-flex RF coaxial construction
• Length: 25 metres
• Connector 1: N male
• Connector 2: RP‑TNC male
• Impedance: 50 ohm characteristic impedance
• Typical application frequency range: HF/VHF/UHF and selected microwave bands (dependent on system requirements)
• Mechanical flexibility: UltraFlex-rated for tight bending and frequent handling

How to use

Align the N male and RP‑TNC male connectors with their respective mating ports and secure by hand-tightening; for the N connector, tighten the coupling nut until it is snug and, if necessary, use an appropriate torque wrench to the manufacturer’s recommended torque to avoid over-tightening. Route the 25 m cable avoiding sharp bends, kinks and close proximity to high-power mains cables to minimise interference. Ensure connectors and cable ends are clean and dry before connection, and verify continuity and VSWR with appropriate test equipment if precision performance is required.

Usage recommendations

For longest service life, avoid repeated tight bends near connector ends, protect exposed connectors from moisture with appropriate weatherproof boots or tape for outdoor use, and store the cable coiled without sharp creases. Use 50 ohm equipment and observe connector gender requirements to prevent damage to devices and maintain expected RF performance.
