Coaxial cable N male to N female Rangeful HF400 3 m, 50 Ω, full copper

Rangeful HF400 3 m coaxial cable with N male to N female connectors is a 50 Ω RF cable designed for reliable signal transfer between antenna systems, test instruments and RF equipment. The cable uses a full copper center conductor and N-type threaded connectors to ensure consistent impedance and low insertion loss across typical VHF/UHF frequency ranges. The 3-meter length provides convenient reach while maintaining mechanical flexibility for installations and temporary test setups.

Advantages

The full copper conductor minimizes DC resistance and contributes to low attenuation, while the HF400 cable construction offers controlled characteristic impedance for stable performance. N-type connectors provide robust mechanical and electrical mating with good shielding against external interference. The threaded connection reduces the risk of accidental disconnects and maintains repeatable contact quality during frequent reconnections.

Suitable for

• Connecting antennas to transceivers and repeaters
• Linking RF test equipment, spectrum analyzers and signal generators
• Temporary and permanent installations in VHF/UHF systems
• Laboratory setups and field measurements requiring a 50 Ω interface

Key specifications

• Impedance: 50 Ω
• Length: 3 m
• Connector A: N male (threaded)
• Connector B: N female (threaded)
• Center conductor material: full copper
• Cable type: HF400-class coaxial
• Typical use: RF and antenna connections

How to use

Before connection, inspect both connector interfaces for dirt or damage and ensure equipment is powered down to prevent signal or DC exposure. Align the N male and N female connectors, engage the threads by hand and tighten until finger-tight; use a torque wrench if specific torque values are required by your equipment. Route the cable to avoid sharp bends and strain on the connectors; maintain bend radius recommended for HF400-style coaxial cable and secure with straps or clamps as needed. For test measurements, maintain consistent connection practice to ensure repeatable results.

Usage recommendations

Store the cable coiled without kinks and keep connectors protected with caps when not in use. Avoid excessive bending near connector ends and minimize exposure to moisture and corrosive environments to preserve connector integrity and electrical performance.
