Coaxial cable Rangeful HF400-RPSM-NM-3 — Full copper, 50 Ω, 3 m

Coaxial cable Rangeful HF400-RPSM-NM-3 is a 3-meter, 50 Ω full-copper RF cable engineered for signal transfer between antennas, radios and related equipment. The cable uses full copper conductors to provide consistent conductivity and aims to minimise transmission loss over short runs. The RPSM to NM connector pairing allows connection to common antenna and radio ports used in amateur radio, routers and test setups. The construction is intended for both indoor and outdoor installations where a flexible, durable coaxial lead is required.

Advantages

The full copper conductors offer improved electrical conductivity compared with plated alternatives, which helps reduce insertion loss across the 3 m length. The 50 Ω impedance is suitable for RF systems and matching with typical antenna and radio equipment. The RPSM to NM connector combination provides a secure mechanical and electrical connection for many standard external antenna and transceiver interfaces. The cable’s jacket and assembly are designed to withstand routine indoor use and common outdoor mounting situations.

Suitable for

• Connecting amateur radio transceivers to external antennas
• Linking routers or access points with external antennas
• Temporary or permanent test bench RF measurements and setups
• Short outdoor antenna runs where a 3 m length is appropriate

Key specifications

• Cable length: 3 m
• Nominal impedance: 50 Ω
• Conductor material: full copper
• Connector types: RPSM (one end) to NM (other end)
• Application: RF signal transmission for antennas, radios and networking devices

How to use

Confirm compatibility of the RPSM and NM connectors with your antenna and radio or networking device before installation. Route the cable to avoid sharp bends and prolonged compression; maintain a gentle bend radius to preserve conductor and shielding integrity. Secure connections by hand-tightening connectors as designed and avoid over-tightening. For outdoor runs, position the cable to minimise prolonged UV exposure and mechanical abrasion where possible.

Usage recommendations

Use this 3 m, 50 Ω full-copper coaxial cable for short RF interconnections where low loss and standard connector compatibility are required. For longer runs or installations exposed to extreme weather, consider evaluating cable routing, additional protection or a cable type specifically rated for prolonged outdoor exposure.
