Coaxial Cable Rangeful HF400-BNCM-NM-30 — BNC Male to N Male, 30 m, LMR400 UF / HF400 equivalent

Rangeful HF400-BNCM-NM-30 is a 30-meter flexible coaxial cable assembly with a BNC male connector at one end and an N male connector at the other. Constructed to be equivalent to LMR400 UF / HF400, this cable is intended for RF signal transmission, antenna feeds and interconnection of radio, telecom and test equipment. Its construction balances low insertion loss with mechanical flexibility to assist routing in indoor racks, cabinets and outdoor runs where a durable yet pliable coax is required.

Advantages

The cable offers low-loss RF performance across typical VHF/UHF and microwave bands for LMR400-class coax, combined with a flexible dielectric and outer jacket that simplify installation around bends and through conduit. Factory-attached BNC male and N male connectors provide standard, widely compatible interfaces for test instruments, transceivers, routers and antennas. The 30 m length reduces the need for additional adapters or in-line joints in many installations.

Suitable for

• Connecting antennas to transceivers and base stations where BNC and N connector interfaces are used
• RF test setups and laboratory equipment requiring standard BNC-to-N adaptions
• Indoor and sheltered outdoor routing that benefits from a flexible LMR400-equivalent cable
• Telecom patching and temporary outdoor deployments where a mid-range length (30 m) is appropriate

When it may not be suitable

This cable is specified as an LMR400 UF / HF400 equivalent and is intended for general RF use; it may not meet specific manufacturer warranty or certified-installation requirements that mandate original factory-branded or certified coax. For extreme low-loss demands at very high microwave frequencies or for runs significantly longer than 30 m, a larger-diameter low-loss cable may be preferable to minimise attenuation.

Key specifications

• Length: 30 m
• Connector A: BNC male
• Connector B: N male
• Cable type: LMR400 UF / HF400 equivalent flexible coax
• Typical use: RF signal transmission and antenna feedlines
• Construction: foam dielectric, shielded coaxial design with flexible outer jacket

How to use

Inspect connectors for dust and damage prior to connection. Thread the N male connector onto the mating female thread until hand-tight, then use a torque wrench to the appropriate torque recommended by the mating connector manufacturer if required. Push the BNC male onto the female BNC and twist the coupling nut until it snaps into place. Route the cable avoiding sharp bends and mechanical pinch points; maintain recommended bend radius for LMR400-style coax to preserve electrical performance. If the cable is used outdoors, secure it with UV-resistant ties and provide weatherproofing at connector interfaces if exposed to the elements.

What to consider before purchase

• Verify connector compatibility (BNC male to N male) with your equipment ports
• Confirm that 30 m length and LMR400-equivalent attenuation meet your link budget requirements
• Assess environmental exposure: require additional sealing or conduit for long-term outdoor use
• Check whether a certified or branded coax is required for warranty or regulatory compliance

Usage recommendations

For best performance, avoid coiling the cable tightly and maintain a bend radius no smaller than the manufacturer’s recommendation for LMR400-class cable. When making permanent outdoor installations, use appropriate weatherproofing at N and BNC terminations and support the cable at regular intervals to prevent strain on connectors.
