Amosphere NPM Installation Procedures (WCS)
Install the GPS Antennas
This procedure describes how to install two Zyfer GPS antennas on top of 1-
inch-diameter, hollow pipes using the supplied hardware. Consult your E1
package for any site-specific GPS antenna installation requirements.
The NPM uses two GPS antennas for redundancy purposes—they do not affect
each other’s operation and they can be installed in close proximity to each other.
Figure 4.20 shows the Zyfer GPS antenna assembly.
