Antenna Configuration

Two (2) antennae are mounted and installed on the roof of the vehicle using specific
measurements for distance.
To mount and install the antennae, perform the following steps:
Step 1 Install antennae (see the figure below).

Observe correct separation between antennae (refer to Table 7: Mobile Antenna
Distance Matrix). This table provides midpoint distance calculations and minimum and
Near-Field Exclusion Zone (NFEZ) for proper diversity reception.
a
The NFEZ distance is an absolute minimum. The greater the distance between the
antennae 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.
