Grounding Switch

Grounding Switch

 

a double-throw switch used for direct grounding of an outside antenna.

In one position the grounding switch connects the antenna to the radio equipment (the transmitter or the broadcast receiver); in the other position it connects the antenna to a grounding device, thus protecting the radio equipment from the dangerous effects of any strong atmospheric electrical charges, such as lightning, that may occur nearby.
