Alfa ALR62NF RF Coaxial Surge Protector, N-Female / N-Female, 0–6 GHz, 50Ω, 10 kA

The ALFA Network ALR62NF is a professional RF coaxial lightning and surge protector for connections operating across a 0–6 GHz frequency range. It uses N Female connectors on both sides, allowing it to sit directly within a compatible coaxial path without changing connector gender. Its 50 Ω impedance matches the stated RF system impedance, while a VSWR below 1.5 and 0.2 dB insertion loss describe how the protector behaves when added to the signal line. These values matter because the protective component becomes part of the RF transmission path and therefore must be selected with the connection’s electrical characteristics in mind. The protector is housed in a nickel-plated brass body.

Protection characteristics include a 90 V DC breakdown voltage and a maximum withstanding current of 10 kA under an 8/20 µs test condition. Together, these figures define the documented voltage threshold and surge-current capability of the device for the intended coaxial installation. The ALR62NF is rated for 50 W and specifies 10,000 MΩ insulation, while electrode capacitance is no more than 1.5 pF. These electrical parameters complement the RF characteristics by defining how the protector is designed to operate within the coaxial connection while providing lightning and surge protection. With its 0–6 GHz coverage, 50 Ω impedance, N Female interfaces, and documented surge ratings, the ALR62NF is a dedicated protective component for compatible RF coaxial systems.
