1. Installation for short cable length and short mast close to the gateway:
This is the simplest case and best option if the
gateway is not far from the antenna, typically the RF
cable length outdoors should be 2 meters or less,
although cable length indoors may be larger.
In this case the lightning arrestor can be attached
directly to the antenna and properly grounded.
2. Installation for medium/long RF cable and short mast:
This setup where gateway is far from the antenna
requires longer outdoor cable. Typically the RF cable
length outdoors being more than 2-3 meters is
considered enough to configure the way depicted in
the figure.
In this case attaching the Lightning Arrestor directly to
the antenna is not best practice, because energy
captured by the cable is not grounded and protected
correctly.
The lightning arrestor should be close to the gateway,
absorbing energy and diverting it to ground.
