How to use

Align the SMA connector with the mating coaxial receptacle and gently engage the threaded coupling until hand-tight. Do not overtighten; use only finger force or a torque wrench set to the recommended torque for SMA connectors if precise tightening is required. Ensure cable and connector cleanliness before connection to maintain signal integrity.

Recommendations

Store the connector in its polybag until installation to protect threads and contact surfaces. When used in sensitive RF systems, verify connector condition and impedance matching to minimise reflections and signal loss.
