Grounding cable and screws
Grounding cable should be with >1 mm
2
copper conductor with insulation, preferable
green/yellow coded for easy ground recognition. Cable should be joined to grounding connector
by crimp connection (pictured). Grounding should be terminated to a grounding rail or other
reliable grounding source with shortest possible cable length to avoid ground loops and
elevated resistances in cables. If longer cable is needed, cable thickness should be increased
accordingly.
Two different screw types are included in the installation kit. Screw type A is M3 countersunk
screw and is used to attach the installation plate to the modem housing.
Screw type B is used for grounding connector attachment.

Grounding the antenna
Grounding the antenna is recommended when antenna is located outside on a mast or long
pole where it is prone to lightning strikes or other high energy disturbances.
Grounding is best to locate as near as possible to the expected disturbance to occur, in practise
at the point where the antenna is fixed to a structure. Wiring the antenna ground and/or cable
shield should be done to a ground rail or other reliable common ground with shortest possible
cable length to avoid high resistance ground loops. If grounding cable is needed to be longer
thicker cable should be used accordingly. Copper cable is preferred for highest conductivity.
It is not recommended to use the mast only as a grounding conductor as its conductivity
can’t
be always guaranteed.
