Earthing and Lightning Protection
WARNING:
Lightning can easily damage electronic equipment.
To avoid this risk, install primary lightning protection devices on any interfaces that
are reticulated in the local cable network.
You should also install a coaxial surge suppressor on the radio antenna port.
Feeder Earthing
Earth the antenna tower, feeders and lightning protection devices in accordance with the appropriate local
and national standards. The diagram below shows the minimum requirements.
Use grounding kits as specified or supplied by the coaxial cable manufacturer to properly ground or bond
the cable outer.
Radio Earthing
The Aprisa SRi has an earth connection point on the top left of the enclosure. M4 8mm pan pozi machine
screws and M4 lock washers are supplied fitted to the radio. These screws can be used to earth the enclosure
to a protection earth.
