1. Provide a grounding strap/cable (of
adequate gauge for the length) to
provide a good ground drain for the
antenna pedestal. This cable/strap
must also be insulated where it may
be exposed to weather.
NOTE: Minimum gauge should not be
smaller than
10 AWG
, even for a short cable
run.
2. Route the ground cable/strap into
the radome with the coax and
power cables.
3. Connect grounding strap/cable to
the burnished ground point on the
upper base plate.
4. Route the ground strap/cable
through one of the Roxtec®
Multidiameter® blocks with the
other power and coax cables.
5. Connect the other end of the
grounding strap/cable to a
burnished ground point on, or near,
the mounting surface. Bi-metal
coupling plate may be required to
get good electrical coupling.
Protective coating should be
applied to prevent the grounding
point from rusting or corroding.
3.5. Removing the Shipping/Stow Restraints PRIOR to Power-Up
The order in which 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).
