Antenna Configuration
Two (2) antennas are mounted and installed on the roof of the vehicle using specific
measurements for distance.
To mount and install the antennas, perform the following steps:
Step 1 Install antennas (see Figure 16).
Observe correct separation between antennas (refer to Table 10: Mobile Antenna
Distance Matrix). This table provides midpoint distance calculations and minimum and
Near-Field Exclusion Zone (NFEZ) for proper diversity reception.

The NFEZ distance is an absolute minimum. The greater the distance between the
antennas to any other surfaces will result in improved performance.
Step 2 Cut a mounting hole in the roof of the vehicle using an electric drill or hole saw.
The antenna-mounting hole provides ground connection to the antenna. Ensure that a
metal-to-metal connection between the antenna shields exists.
