Coaxial cable Rangeful RP-SMA male to N male HF400 10 m 50 Ω full copper flexible

Rangeful HF400 coaxial cable with RP-SMA male to N male connectors is a 10 m, 50 Ω flexible RF cable designed for reliable signal transmission between radios, antennas and RF equipment. Built with full copper inner and outer conductors and a flexible dielectric, the cable offers consistent electrical performance and reduced insertion loss for use in ham radio, test setups, base stations and other RF installations where a durable, low-loss cable is required.

Advantages

The full copper conductors ensure good conductivity and improved shielding compared to plated alternatives, supporting stable transmission across RF frequencies. The flexible HF400 construction allows easy routing through equipment racks and tight spaces while maintaining mechanical strength. Corrosion-resistant connectors and solid assembly provide consistent mating and long-term reliability in indoor and sheltered outdoor environments. The 50 Ω characteristic impedance matches common RF devices to minimize reflections and standing wave ratio (SWR) issues.

Suitable for

• Connecting ham radio transceivers to antennas
• Linking signal generators, spectrum analyzers and measurement equipment
• Base station and repeater RF runs in sheltered installations
• Temporary or semi-permanent test setups and bench connections

Key specifications

• Length: 10 m
• Characteristic impedance: 50 Ω
• Inner conductor material: full copper
• Outer conductor/shield: full copper braid/foil
• Connector A: RP-SMA male
• Connector B: N male
• Cable type: HF400 (flexible)
• Application: RF signal transmission

How to use

Attach the RP-SMA male connector to the corresponding RP-SMA female port on the radio or adapter, ensuring the connector engages and is tightened to hand-tight plus a small wrench turn if required. Connect the N male connector to the antenna feedline or test instrument by threading the N connector onto the mating N female and securing it firmly. Route the cable to avoid sharp bends, crushing or kinking; maintain bend radii recommended for flexible HF400 cable to prevent performance degradation. Inspect connectors for cleanliness and proper mating before each critical measurement or transmission.

Usage recommendations

For best performance, minimize cable length where possible and avoid coiling the cable tightly. Use proper torque on connector interfaces to prevent damage and ensure low-loss contacts. Store the cable coiled loosely and protect connector ends with caps when not in use. For outdoor installations, place the cable in sheltered locations or use additional weatherproofing at connector joints to reduce exposure to moisture and corrosion.
