How to Properly Crimp and Maintain SMA Connectors
Proper installation and maintenance are vital to preserve SMA connector performance:
Crimping: Use the correct stripping dimensions and ratcheted crimp tools to avoid insertion loss or damage.
Torque: Apply the recommended torque — 0.3 to 0.6 Nm for brass, 0.8 to 1.1 Nm for stainless steel — using a torque wrench to ensure a secure connection.
Cleaning: Inspect and clean mating surfaces with compressed air or gas duster before connecting to maintain low VSWR.
Avoid Cross-Mating: Do not mate standard SMA connectors with RP-SMA or Type F connectors without adapters to prevent damage.
