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:

SRM9000AC (150-174MHz).
Mobile Antenna:
