Vehicle Installation Instructions:
The antenna(s) used for the SRM9000series of mobile two-way radios must be
installed to provide a separation distance of at least 75cm from all persons for
SRM9000UW (440-512MHz) and 90cm for SRM9000AC (150-174MHz). The
gain of the antenna(s) may not be greater than 0dBd (2.14dBi).
If the required separation distance extends beyond the physical boundary of
the vehicle, the antenna must be installed on the center of the roof ONLY and
must be installed in a vehicle having the following characteristics in order to
prevent bystanders from being exposed to levels exceeding the limits set for
General Population/ Uncontrolled exposure environment:
• All passengers must be sitting under a solid metal roof
• The rooftop width must be at least 150cm (59 inches) for
SRM9000UW (440-512MHz), or 180cm (71 inches) for
SRM9000AC (150-174MHz).
Mobile Antenna:
• Install the antenna at the center of the roof or the center of the trunk
deck, taking into account the bystander exposure conditions of
backseat passengers and recommended minimum lateral distances in
Table 1a) and 2a). These mobile antenna installation guidelines are
limited to metal body motor vehicles or vehicles with appropriate
ground planes.
• The antenna installation must additionally be in accordance with:
a.) The requirements of the antenna manufacturer/supplier
b.) Instructions in the Radio Installation Manual, including minimum
antenna cable lengths.
c.) The installation information of how to install the antenna to
