ATTENTION!
The MOBEXCOM DVE is intended for use in occupational / controlled conditions, where users have
full knowledge of their exposure and can exercise control over their exposure to meet FCC limits. This
radio is NOT authorized for general population, consumer, or any other use.
ANTENNA INSTALLATION
IMPORTANT
The maximum allowed gain of the λ/4 omni-directional antenna for the Mobexcom DVE is Unity (0dBd).
IMPORTANT
To assure optimum performance and compliance with RF Energy Safety standards, these antenna
installation guidelines and instructions are limited to metal-body vehicles with appropriate ground planes
and take into account the potential exposure of back seat passengers and bystanders outside the
vehicle.
Selecting an Antenna Site/Location on a Metal Body Vehicle
External installation
Check the requirements of the antenna supplier and install the vehicle antenna external to a metal body
vehicle in accordance with those requirements.
Roof top
For optimum performance and compliance with RF Energy Safety standards, mount the mobile radio antenna
in the center area of the roof.
Trunk lid
For optimum performance and compliance with RF Energy Safety standards, mount the DVE antenna in the
center area of the trunk.
Before installing an antenna on the trunk lid:
 Ensure that the distance from the antenna location on the trunk lid will be at least 66 cm (26 inches) from the
front surface of the rear seat-back to assure compliance with RF Energy Safety standards.
 Ensure that the trunk lid is grounded by connecting grounding straps between the trunk lid and the vehicle
chassis.
 Ensure that the antenna cable can be easily routed to the radio. Route the antenna cable as far away as
possible from any vehicle electronic control units and associated wiring.
 Check the antenna location for any electrical interference.
NOTE:
Any two metal pieces rubbing against each other (such as seat springs, shift levers, trunk and hood lids,
exhaust pipes etc.) in close proximity to the antenna can cause severe receiver interference.
