Mobile Radio Operation and EME Exposure Mobile Antenna Installation
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.
Table 1: Radiated Power and Distance
Radiated Power of | Minimum Distance |
From Transmitting | |
Mobile | Antenna |
|
|
7 to 15 Watts | 30.5 cm(1 Foot) |
|
|
16 to 50 Watts | 61 cm (2 Feet) |
|
|
More than 50 Watts | 91.5 cm (3 Feet) |
|

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.
