■
For structural members between 4 and 10 inches in diameter, use a sliding scale of 2 to 5
feet. (For example, a 24-inch standoff at 4-inch diameter to a 60-inch standoff at 10-inch
member diameter.)
■
Inform Itron about any conditions that may impact the collector or repeater performance.
Grounding the Antenna System
To minimize the potential for a lightning event, it is essential that remote/external antenna
systems be properly grounded. Proper grounding prevents the accumulation of static charges on
the antenna system, and also provides a direct discharge to ground for any acquired charges.
All grounding materials and procedures must meet or exceed local codes. Use coaxial grounding
kits recommended by the coaxial cable manufacturer.
Warning! Under no circumstances should the antenna grounding wires be run inside
a building. Always install ground bars and grounding material on the building'sexterior.
Grounding an Antenna System
1. Mount a copper ground bar near the antenna. This is the top ground bar.
2. Mount a second copper ground bar near the collector or repeater. This is the bottom ground
bar.
3. Connect the two ground bars with a #6 gauge green jacketed stranded wire or a #2 solid
copper wire.
4. Ground the antenna mount and the top coaxial ground kit to the top ground bar.
5. Ground the bottom coaxial ground kit and the lightning arrestor to the bottom ground bar.
6. Connect the bottom ground bar to one or more earth ground rods.
7. All ground wires should be connected straight to ground, with no right angle turns or sharp
bends in the wires.
8. Install ground leads on coaxial grounding kits without loops or bends.
9. Install grounding kits in the proper orientation per the manufacturer's specifications.
For more information about grounding and bonding, see Grounding Specifications on page 103.
915 MHz Antenna
The 915 MHz antenna transmits and receives data messages from endpoints and repeaters in
the network.
