Coaxial cable Rangeful HF400 N male to N male, 50 Ω, flexible HF400, length 5 m

Coaxial cable Rangeful HF400 N male to N male, 50 Ω, flexible HF400, length 5 m is a 5-metre RF coaxial cable with N male connectors on both ends and a characteristic impedance of 50 ohms. The cable uses a flexible HF400 construction designed for RF signal transmission where moderate flexibility and low loss are required. It provides N-type threaded terminations that ensure reliable mechanical connection and stable electrical contact for antenna feeds, test setups and radio equipment interconnects.

Advantages

The flexible HF400 construction balances bending radius and shielding effectiveness, enabling easier routing in cramped installations while maintaining consistent impedance. N male to N male connectors offer durable threaded coupling that resists loosening and supports repeatable, low-loss connections. The 50 Ω impedance matches common RF equipment and antennas to minimise reflections and preserve signal integrity over the 5 m length.

Suitable for

• Amateur radio antenna feeds and transceiver connections
• Base station and repeater interconnects
• RF test equipment and laboratory setups
• Temporary and permanent installations requiring flexible routing

Key specifications

• Connector type: N male to N male
• Impedance: 50 Ω
• Cable type: flexible HF400 coaxial
• Length: 5 m
• Typical use: RF signal transmission for VHF/UHF and related bands

How to use

Inspect connectors for cleanliness and tighten N-type threaded couplings by hand and then secure with an appropriate torque wrench if available to ensure reliable contact without over-tightening. Route the cable respecting a modest bending radius to avoid excessive stress on the dielectric and outer conductor; avoid tight kinks. Connect one N male end to the radio, amplifier or test instrument and the other to the antenna or measurement device. For permanent outdoor runs consider additional weatherproofing at the connector junctions.

Usage recommendations

For optimal RF performance, keep runs as short as practical and avoid sharp bends. Periodically check connector tightness and corrosion, especially in outdoor or humid environments. Use compatible 50 Ω equipment and, where appropriate, apply low-loss sealing methods at outdoor connectors to prevent moisture ingress.
