Special Antennas Installation Considerations
General Antenna Installation Safety Considerations
The antennas must be installed in a location that will ensure a distance of
at least 8” (20 cm) between any of them and any bystander.
If your vehicle is equipped with PSNB (Public Safety Narrow Band) equipment,
special attention must be taken when installing the antennas. A minimum distance
of 78” (198 cm) must be kept in order to ensure coexistence between all systems.
Main Antenna
The antenna must be installed on a flat metal surface (minimum size 24” (61 cm) x 24” (61 cm)).
The main antenna must be installed on the vehicle’s roof, preferably in the center front side
of it. Make sure that the vehicle roof material is metal. If not, use a 2 ft x 2 ft metal ground
plane and mount the antenna in its center. For best performance, a minimum distance of
36” (91.44 cm) must be kept between this antenna and any other antenna.
