Grounding for Indoor/Outdoor Units
ODU Grounding
RADWIN Ligtning Protection System uses a Shielded CAT-5e cable to inter-
connect the Outdoor (ODU) and Indoor (IDU) units.
However, this shielding does not provide a good lightning discharge path,
since it can not tolerate the high Lightning Current surges.
To provide an alternate Lightning Discharge path, the ODU and antenna
grounding posts should be connected to ground point by a 10 AWG short
copper wire.
The device should be permanently connected to ground.
IDU Grounding
The IDU’s grounding post should be connected to the internal ground point,
using a grounding wire of at least 10 AWG. The grounding wire should be
connected to a grounding rod or the building grounding system.
The device should be permanently connected to ground.
