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.
Installing the AL-1 Lightning Arrestor
1. Connect the antenna to the AL-1 input, as shown in Figure 2-15.
2. Connect the AL-1 ground connector to the building’s safety ground.
3. Connect the antenna from the AL-1 output to the antenna input in the modem.
