1. Connect the ground wire (of
adequate gauge for the length) to a
burnished ground point on, or near,
the mounting surface. This
burnished grounding point must be
electrically common with the hull.
Bi-metal coupling plate may be
required to get good electrical
coupling to the hull of the ship.
Protective coating should be
applied to prevent the grounding
point, and ground wire, from rusting
or corroding.
NOTE: Minimum
gauge should not be
smaller than
10 AWG
, even for a short cable
run.
2. Route the ground cable/strap up
through the radome base with the
coax and power cables.
3. Route the ground strap/cable
through one of the Roxtec®
Multidiameter® blocks with the
other power and coax cables.
4. Connect the grounding strap/cable
to the burnished ground point on
the upper base plate.
3.5. Removing the Shipping/Stow Restraints PRIOR to Power-Up
The order the restraints are removed is not critical.
CAUTION: There are three shipping/stow restraints on this antenna pedestal
that
MUST be removed, before energizing the antenna, for normal operation.
3.5.1. Removing the AZ Shipping/Stow Restraint
1. The AZ shipping/stow restraint is formed by a
pin bolt that is lowered into a channel in a
stowage block on the upper plate of the
pedestal (as shown).
2. To un-stow the antenna, remove the pin bolt
from the LOCK position.
