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.
17.2.1. 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).
