2.9. Grounding
All metal parts of the ADE shall be grounded to bare metal that is common to the hull of the ship. This is most
commonly accomplished by attaching a ground wire/cable from the upper base plate ground point to a ground stud on
the mounting pedestal/stanchion/mast near the base of the radome. Preservation of the bare metal contact point
should be done to prevent loss of ground due to rust and/or corrosion.
Grounding by exposing bare metal under all mounting bolts of the under-side of the radome base prior to final
tightening does NOT provide adequate grounding of the ADE.
Grounding should be ensured throughout the entire mounting to the hull. While it is presumed the deckhouse is
permanently bonded and grounded to the hull, in cases where the deckhouse and hull are of different materials a
check of an independent ground bonding strap should be made. Masts should be confirmed to be grounded to the
deckhouse or hull.
