Grounding Requirement
Good grounding is the basis of reliability and stability of devices. Good grounding are the
most important guarantee of lightning arresting and interference rejection.
Coaxial cable’s outer conductor and isolation layer should keep proper electric
conducting with the metal housing of device.
Grounding conductor must adopt copper conductor in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.
It is prohibited to use any other device as part of grounding electric circuit
The area of the conduction between grounding wire and device’s frame should be no less
than 25mm
