Procedure 9 Mounting the GPS antenna
1
Ensure that the mounting position
•
has an unobstructed view of the sky to 20º above the horizon.
•
is not the highest object at the site. (The GPS antenna does not need to be
particularly high on a site, which would give it more exposure to lightning. It
just needs to have an unobstructed view of the sky.)
•
is not further than 100 feet (30.4 meters) of cable from the CMM.
2
Select a pole that has an outside diameter of 1.25 to 1.5 inches (3 to 4 cm) to which
the GPS antenna bracket can be mounted.
3
Place the U-bolts (provided) around the pole as shown in
.
4
Slide the GPS antenna bracket onto the U-bolts.
5
Slide the ring washers (provided) onto the U-bolts.

Slide the lock washers (provided) onto the U-bolts.
