Mobile Radio Operation and EME Exposure
To assure optimal radio performance and that
human exposure to radio frequency electromagnetic
energy is within the guidelines referenced earlier in
this document, transmit only when people inside
and outside the vehicle are at least the minimum
distance away from a properly installed, externally
mounted antenna.
Table 1 lists the minimum distance for several
different ranges of radiated power.
Mobile Antenna Installation
Install the vehicle antenna external to the vehicle
and in accordance with:
•
The requirements of the antenna manufacturer/
supplier
•
Instructions in the Radio Installation Manual
Control Station Operation
When radio equipment is used to operate as a
control station, it is important that the antenna
be installed outside the building and away from
places where people may be in close proximity.
Refer to Table 1 for rated power and minimum
distant values for transmitting antennas.
