Vehicle Antenna Installation Guide
INTRODUCTION
When installing any TETRA antenna to a vehicle, it is the responsibility of the installer to
ensure that the location of the antenna is considered not only for best RF performance but
more importantly in order to minimize the potential for RF exposure to third parties.
To minimise the potential risk of RF exposure to third parties, antennas should ideally be
fitted to locations on the vehicle that ensures that the distance between the radiating
antenna and third parties is at least 20cm, or if greater, the minimum safe distance required
to meet the General Exposure limit for that antenna fitted.
If this General Exposure distance cannot be met then the radiating antenna must be
placed in a location that ensures the Occupation limit cannot be exceeded.
A list of minimum distances for Sepura supplied TETRA antennas are shown in table 1
below. The outline drawing below shows one example of how third parties may come into
proximity of the installed antenna.
Fitted antenna
Should it not be possible to maintain the minimum safe distance between third parties and
the radiating antenna, then action must be taken by the installer to reduce the potential for
exposure at the specified minimum distance such that the Occupational Exposure limits are
not exceeded.
