Additional Details:

The SA4020-30 typically features SMA connectors. It's crucial to verify the specific frequency range, surge handling capacity, insertion loss, and VSWR (Voltage Standing Wave Ratio) in the product datasheet. Grounding is a critical aspect of surge arrester installation and the quality of the grounding connection can significantly impact its performance. Proper installation according to the manufacturer’s guidelines is required for optimal surge protection.
