Coaxial cable N male to N female Rangeful HF400 7 m, full copper, 50 Ω

This is a 7 m Rangeful HF400 coaxial cable with N male to N female connectors, constructed from full copper and rated at 50 Ω. The cable is designed for RF signal transmission with a fixed length and standard N-type connectors to provide a stable mechanical and electrical connection between antennas, transceivers, and test instruments. The full-copper conductor and shielding deliver consistent signal conductivity and help reduce insertion loss across typical VHF/UHF frequency ranges.

Advantages

The Rangeful HF400 cable combines a full-copper center conductor with a copper shield to ensure good conductivity and shielding effectiveness. Standard N male to N female terminations provide secure threaded coupling and compatibility with professional RF equipment. The 7 m length offers flexibility for routing between radios and antennas without excessive signal loss common to longer, lower-quality cables. The cable is rated at 50 Ω, matching common radio and test equipment impedance to minimize reflections.

Suitable for

• Antenna feedlines for VHF/UHF transceivers
• Connections between radio equipment and external antennas
• Laboratory and field test setups requiring stable 50 Ω cabling
• Short to medium run installations where fixed-length, threaded N connectors are preferred

Key specifications

• Cable type: HF400 coaxial
• Length: 7 meters
• Connectors: N male (one end) to N female (other end)
• Conductor and shield material: full copper
• Characteristic impedance: 50 Ω
• Typical use: RF signal transmission for VHF/UHF bands

How to use

Connect the N male end to the corresponding female connector on the antenna or feeder and the N female end to the radio, transceiver, or test instrument, ensuring threaded couplings are hand-tightened and then secured with appropriate torque if specified by the connected equipment. Avoid sharp bends near the connectors and route the cable to minimize exposure to mechanical stress, crushing, or repeated flexing. For installations exposed to the elements, protect connections with appropriate weatherproofing components.

Usage recommendations

Match the 50 Ω impedance of this cable with equipment rated for 50 Ω to reduce VSWR and signal reflections. Keep cable runs as short as practical for the application to limit insertion loss, and inspect connectors periodically for corrosion or loosening, especially in outdoor environments.
