Proprietary and Confidential
Itron recommends using a handheld GPS unit to verify that your GPS antenna mounting
location can receive a signal from at least three satellites.
If you are using a GPRS WAN backhaul, Itron recommends testing the GPRS antenna at
your desired installation to ensure that GPRS service is available at that location.
For more information, see GPS and WAN Coverage on page 8.
Caution The GPS antenna must be oriented vertically when installed, and it must
have an unobstructed view of the sky to properly receive a GPS signal.
The GPS/WAN antenna system is shown below.
