Do not locate the antenna underneath high power lines. If this cannot be avoided,
ensure the antenna is placed at least twice as far from the power line as the power
line is high (to avoid danger to personnel or multipath effects).

Earth Ground Location Guidelines
The roof ring ground system, a Central Office grounding plate, and building
structural steel are examples of valid earth ground points. If the mounting plate
cannot be bolted to a valid earth ground, or if the mounting plate is to be installed in
a nonmetallic junction box, bolt the mounting plate to a point within 4.6 m of the valid
earth ground.
Note: Figure 2-3 illustrates a sample installation. Not all parts are
available from Symmetricom.
