Introduction
Shielded cable
The installation infrastructure (towers and masts), as well as antennas and
the router itself must be properly grounded, and lightning arrestors must
be installed on all external antenna cables (near the antennas or on the
antennas themselves) to prevent equipment damage and human injury.
Note that lightning arrestors will not have any effect if not grounded.
Use 1 AWG (7mm in diameter) wire with corrosion-resistant connectors
for grounding. Be sure to check that the grounding infrastructure you use
is indeed functional (as opposed to decorative-only grounding present on
some sites). For smaller devices you can use thinner wire.
1.1. Only shielded and outdoor usage Ethernet cables should be used,
magnetic shield should be grounded via shielded RJ-45 connector or
via additional wire that is soldered to RJ45 or ground wire.
2.2. Grounding wire should be connected to RouterBOARD (to the
mounting point where board is fastened to the outdoor box), this wire
is connected to bottom of the tower and connection to the tower is
according to the standards. Antenna grounding wire is connected near
RouterBOARD Outdoor case, this wire could be connected to the same
RouterBOARD grounding wire.
3.3. Ethernet port ligthing protectors are not recommended, as most of
them are not intended to use for PoE (they are shortening PoE supply).
If protectors are used, they could be placed at the outdoor case, where
RouterBOARD and grounding pads are connected.
