Coaxial cable Rangeful HF400-RPSM-NMH-30 30 m, full copper, 50 Ω

Rangeful HF400-RPSM-NMH-30 is a 30 m coaxial RF cable with full copper conductors and a nominal 50 Ω impedance, intended for reliable signal transmission in antenna, radio and test equipment connections. The cable combines a solid copper center conductor and copper shielding to reduce attenuation and maintain consistent performance across short to medium cable runs. It is fitted with an RPSM (RP-SMA) male connector on one end and an NMH (N female) connector on the other to enable direct mating with a variety of devices and antennas.

Advantages

The cable’s full-copper construction provides stable conductivity and mechanical flexibility for installation and routine maintenance. Its 50 Ω characteristic impedance supports common RF systems and measurement setups, while the specific connector pairing simplifies connections between SMA-based equipment and N-type installations. The 30 m length covers medium-distance runs without the need for repeaters in many applications, and the cable’s shielding and dielectric design reduce signal loss and interference over that distance.

Suitable for

• Connecting antennas to transceivers and routers
• Linking radio equipment and receivers
• Testbench and measurement setups with 50 Ω systems
• Temporary or permanent cabling in installations requiring an RPSM-to-NMH connection

Key specifications

• Cable length: 30 m
• Characteristic impedance: 50 Ω
• Conductor material: full (solid) copper center conductor and copper shielding
• Connector types: RP-SMA (male) to N-type (female)
• Intended frequency range: RF applications (suitable for common VHF/UHF and lower microwave ranges where specified)
• Typical use: short-to-medium range signal transmission with low attenuation

How to use

Inspect connectors for physical damage and ensure mating surfaces are clean before making connections. Route the cable to avoid sharp bends, tight coils or crushing that could deform the dielectric or shielding and increase loss. Hand-tighten the N-type connector using the correct torque recommended for N connectors, and secure the RP-SMA connection by screwing until finger-tight; avoid over-tightening which can damage threads. For measurement setups, verify system impedance matching and use proper termination to minimize reflections.

Usage recommendations

Store and install the cable in environments protected from prolonged moisture exposure and high mechanical stress. For outdoor runs, use additional weatherproofing at connector joints and maintain bend radii greater than the cable’s specified minimum to preserve RF performance.
