Coaxial cable Rangeful HF400-RPSM-NMH-3 — 3 m, full copper, 50 Ω

Coaxial cable Rangeful HF400-RPSM-NMH-3 — 3 m, full copper, 50 Ω is a 3-meter RF connection cable with a solid copper center conductor and 50 ohm characteristic impedance. Designed for signal paths between antennas and RF equipment, this coaxial cable provides stable impedance and reduced insertion loss compared to many mixed-metal alternatives. The cable assembly includes matched connectors for reliable electrical contact and mechanical stability in field and bench environments.

Advantages

The full copper conductor offers higher electrical conductivity and improved signal transfer, while the 50 Ω impedance assures compatibility with common radio and RF systems. The 3 m length balances reach and manageable handling for base station setups and temporary test configurations. The cable's construction emphasizes consistent impedance along its length and mechanical robustness to support repeated connections and moderate flexing without significant degradation of performance.

Suitable for

• Connecting antennas to transceivers in amateur radio stations
• Linking RF test equipment and signal generators in lab setups
• Base station RF feedlines for short runs
• Temporary field installations and portable radio setups

Key specifications

• Cable length: 3 m
• Characteristic impedance: 50 Ω
• Center conductor material: solid copper (full copper)
• Designed for RF signal transmission with low insertion loss
• Connector compatibility: suitable for standard 50 Ω RF connectors

How to use

Connect one end of the coaxial cable to the RF output or antenna port on your radio, transceiver, or test instrument and the other end to the antenna or feed point. Ensure connectors are correctly mated and tightened to maintain good electrical contact; avoid over-tightening which could damage connector threads. Route the cable to minimize sharp bends and crushing; allow gentle curves with a radius larger than the cable diameter to preserve impedance and reduce stress on the conductor and shield.

Usage recommendations

For best long-term performance, inspect connectors periodically for signs of corrosion or loose contact and replace any damaged cable assemblies. Use the cable for runs within the specified 3 m length, avoid exposing it to prolonged moisture or direct sunlight without additional protective measures, and keep connectors clean and dry when storing or transporting.
