DVRS Antenna Installation

Any DVRS Model requires the use of two antennas – one connected to the MSU and
one connected to the DVR. For a list of approved DVR Antennas, please refer to
Appendix 12.
IMPORTANT
To assure optimum performance and compliance with RF Energy Safety
standards, these antenna installation guidelines 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.
The MSU and DVR Antennas must be installed in such way as not to cause interference.
All DVRS models require 30dB minimum Antenna Isolation between the DVR and
MSU Antennas.
It is recommended that the DVRS antennas are installed as follows: one antenna
mounted in the center area of the roof, the other antenna mounted on the trunk lid.
Before installing an antenna on the trunk lid:
 Ensure the distance from the antenna to the front surface of the rear back seat is
greater then the minimum distance specified in the "Product and RF Safety" Booklet
for the specific DVRS model and frequency band.
 Ensure the trunk lid is grounded by connecting grounding straps between the
trunk lid and the vehicle chassis.
To ensure compliance with RF Energy Safety standards, the antenna locations, gain and
maximum Transmit Power (for both the Mobile radio and the DVR) must be as specified
in the "Product and RF Safety" Booklet shipped with the DVR.
NOTE
The DVRS antenna ports (both DVR and XTL sides) are mini UHF male and require
antennas with matching mini UHF female terminations.
