AL-1 Lightning Arrestor

The AL-1 Lightning Arrestor is used to protect transmitters and receivers from transients originating from lightning or EMP. The AL-1 is gas tube-based and is not radioactive. The gas discharge tube can sustain several transients if the time period between transients is sufficient to allow the tube to cool down.

See page 106 for further information.

2.Connect the AL-1 ground connector to the building’s safety ground.
