Vehicle Installation Instructions:
The antenna(s) used for the SDM600 series of mobile two-way radios must be installed to provide a
separation distance of at least 90cm (35.5 inches) from all persons for SDM600AC (150-174MHz), and
75cm (29.5 inches) for SDM600TU and SDM600UW (406.1-512MHz). 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 should be at least 130cm (51 inches).
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 Tables 1a), 2a) and 3a). 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.
