17.1.3. Installing the CL Shipping/Stow Restraint
1. The CL shipping/stow restraint is formed by
a red locking bar with adjustable bumpers at
each end of the bar. This mechanism is
placed under the cross-level beam to lock it
in place (at level).
2. If not already removed, remove an
adjustable bumper by removing the bottom
nut from one end of the locking bar.
3. If not already loosened, loosen the top nut
up toward the rubber bumper.
4. Insert vacant end of the locking bar through
the opening under the cross-level beam.
5. Insert the adjustable bumper into the vacant
hole on the end of the locking bar.
6. To restrain the cross-level axis of the
antenna use a 7/16“ open end wrench to
tighten the nut on the top side of the
locking bar until the rubber bumper is
forced up against the bottom of the cross-
level beam.
7. Verify that the antenna does NOT rotate
(tilt left & right from level).
8. Re-install and tighten the bottom nut on the
underside of the locking bar.
17.2. 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.
