Mobile Radio / DVR Antenna separation
To ensure interference-free performance when both the Mobile Radio and the DVR are active at
the same time, the two antennas must be mounted in such way as to provide 30dB minimum
antenna isolation.
Fixed DVRS Site Antennas
Mobile radio equipment is sometimes installed at a fixed location and operated as a control station
or as a fixed unit. In such cases the antenna installation must comply with the following
requirements in order to assure optimal performance and make sure human exposure to radio
frequency electromagnetic energy is within the guidelines set forth in the above standards.
• The antennas must be mounted outside the building.
• Mount the antennas on a tower if at all possible.
• If the antennas are to be mounted on a building then it must be mounted on the roof.
• As with all fixed site antenna installations, it is the responsibility of the licensee to manage the
site in accordance with applicable regulatory requirements and may require additional compliance
actions such as site survey measurements, signage, and site access restrictions in order to
ensure that exposure limits are not exceeded.
Temporary-Fixed Site
Futurecom requires the P25 Transportable DVRS (TDVRS) operator to ensure FCC/ISED
Requirements for Radio Frequency Exposure are met. It is the responsibility of the Licensee to
ensure that the appropriate separation distances between the antennas and bystanders are
established and followed to meet the FCC/ISED Maximum Permissible Exposure (MPE)
Requirements in any particular Temporary-Fixed location. In situations where a site assessment is
not practical, it is recommended that the antennas be located at least 9 feet (2.74m) from
bystanders. This should ensure MPE compliance in any Temporary-Fixed application and is
likely to be a much greater separation distance than is necessary in most cases. Failure to
observe the MPE distance exclusion area around the antenna may expose persons within this
area to RF energy above the FCC/ISED exposure limits for bystanders (general population).
