3. Insert the 7623 3/4 IPS aluminum pipe into the GPS antenna (see FIGURE
4-5).
4. Mount the 7623 3/4 IPS aluminum pipe to a crossarm via a CM220 mount
or NU-RAIL fitting. FIGURE 4-5 and FIGURE 4-6 show the GPS
antenna mounted to a crossarm using a CM220 mount. The ideal location
for the GPS antenna is above everything, with the shortest cable possible.
Refer to Section 7.4, GPS Antenna, for additional information about the
GPS antenna.
The GPS antenna will not receive a GPS signal through
steel roofs or steel walls. Concrete might also be a
problem. Heavy foliage, snow, and ice will attenuate the
GPS signal. CAUTION
